Thank you for posting this. My 125psi/25 gallon compressor hasn't worked properly for several years. Initially it fills, but won't recycle without blowing the breaker. Upon inspection I found the same broken plastic on an inner cover. My model is slightly different from yours. The switch is just held in place by a properly fit cover. The upper screw hole on the cover had broken so it fit crooked. I notice your switch is held by two screws. Mine had the holes but no screws. A couple of long screws, toothed washers and nuts secures that firmly in place. I tapped the case and used a flat washer with a long screw that now holds the cover on properly. Also, I discovered inside the cover one of the two position terminals had broken off the cover. A 1/8" pop rivet with backing washer put that back in place. It might have been touching one of the other 2 terminals causing a short. Now it works again perfectly restarting with 80 psi in the tank and not popping a 15 amp breaker. I'm glad it wasn't the capacitors. The run cap is easy to find, but the 3 wire start cap is not. Thanks again.
*This does exactly what I was wanting **MyBest.Tools** Price was fantastic, lower than Harbor Freight-and it included hose and attachments, and IT IS MADE IN AMERICA, unlike Harbor Freight*
Found this while searching for a cover/part replacement, as the plastic finally became so brittle I couldn't CA glue it anymore. Thanks for the creative repair idea.
I called 4 repair shops this morning and all said to just buy a new one because repairing mine would be too expensive. I was about to go buy a new one and seen your video. I just tried this exact fix and it worked like a champ! You just saved me several hundred dollars! Thank you!
Like so many others. THANKS for posting this. Saved me $350+ for a new compressor. As I constantly tell my friends, TH-cam is your friend. Even for those over 60 like myself.
I've got a vertical that loves to trip the breaker. You described a Craftsman POS perfectly. This one is my 2nd one and I turned my 1st POS with a pump issue into a great sand blasting rig. When running a construction project there is no time to wait on a fix so I bought the 2nd POS. Now that I have some time and thank you for the video I will troubleshoot this machine and see if I can find as elegant of a solution as you did. The duct tape really gave me a chuckle as I remembered the Red Green show. If the ladies don't find you handsome they had better find you handy!!!
THANK YOU THANK YOU THANK YOU!!! I was losing sleep over this and was dreading the thought of having to buy a new compressor. 😩 I was thinking it could be the starting capacitor but lo and behold I stumbled across this video. This was the EXACT problem I was having...seems to be a common problem with these compressors. 10 minutes later I've got a quick and easy fix and it's back up and running. Rather than making a bracket, I just used a longer threaded screw with some larger washers to hold the cover in place. Seems rock solid! Thank you again for shedding some light on this problem and recording this video. 🙏🏼
I picked a like new vertical air compressor 33 gallon that I think has the same issue. The seller wanted a higher voltage compressor in his garage so I lucked out. He did save the parts (that will eventually fail again) on the cover so I thank you for your wonderful video.
Great info. My 150 quite a week ago just before going out of town. This afternoon I started looking into the problem. I went to Wi-Fi for tips. After watching your u tube, I went back out and pulled the cooling shroud. Lo and behold the damn thing was broken just where yours was. Thank you for this tip and repair.
*Construction seemed sturdier than other units I considered **MyBest.Tools** Noise level was reasonable. Good pressure and cfm capacity for a small reasonably light compressor.*
My compressor had been sitting for a few years. I thought it was the capacitors but that was not the fix so I put it away. I'm restoring a sailboat and needed bigger air, I came across this video, went right to the shed, dusted off the old compressor, did this fix in about 10 minutes and WALA! Good as new. Knowledge is power so I thank you sir for taking the time to make and post this fix.
This worked on my craftsman 33 gal. Great video. Thank you for your contribution to the working class. Did exactly what you did. My cover was also loose. 🙋♂️✌️🇺🇲
Thank you for saving me a lot of time and money trying fix/replace my compressor!! I have the Craftsman 25 gal upright model 919 which is about 25 years old. I was having the same problem except mine quit working all at once and was sparking, smoking, making a grinding noise, and tripping the breaker after a few seconds. I was able to fix my compressor by replacing the top housing mount screw with a 2 1/2 inch screw and a washer. The bottom screw was fine, housing not even cracked. Compressor is running like a champ!🙂
You da man!!! You got my compressor fixed after it sat for 2 years, a guy sold it to me for 100.00 knowing it had this issue, he plugged it in and it came on and he shut it off after 30 seconds my guess knowing the issue, well jokes on him now thanks to you brother!
Craftsman compressor not working told wife gonna try to fix it she said check out you tube first luckily I found your video it was exactly the same issue. My craftsman 33 gal. Compressor was designed just a little different the plastic assembly extended higher on end of motor. But fixed it in a similar manner. Thank you very much you saved us money thank you thank you
Fantastic! You fixed another compressor out here in Virginia! This was the exact failure point and your concise description got me up and running in minimum time. Thanks!!!
Wow, you just saved my husband from buying a 2hole new air compressor. He has the vertical machine and the same issue came about with his. We saw your video and by god, your repair and diagnostics worked like a charm. We both thank you so much for this video.
I was having exact problem you describe. Same 33 gallon tank, but mine is upright tank. Sure enough, back engine cover loose on mine. Secured it tight, and it started right up. Excellent video on what is obviously a common problem with these Craftsman air compressors. Thanks.
A THOUSAND THANK YOU's!!!! I was having the same issue.. Really bogged slow start then blows circuit breaker.. I was just shopping for Start capacitors due to seeing other videos and I decided to you tube one more time for this issue and I found your video.. It just so happens that I was missing the bottom screw holding that Black motor cap on and it was sticking out.. I found a matching screw and went for startup and BAMM!! Shes up and running!!! I cant believe it...👍
Thanks for the information! I got a free 30 gallon from my neighbor because he had the same issue. I ended up 3D printing a replacement cover, extending the mount for the switch 2mm too make a better connection (read online that even from factory that switch sits a little too far back), and making the mounting points thicker to prevent them from braking again. It’s working like brand new now! Hell it looks brand new.. dude barely used it.
@@peloneretana5924 I have the file still, so if it’s the same I could probably make you one. Shoot me your email to my pm. Maybe you can send a pic of your cover so I can see if it’s the same.
Smartest approach for this superior modification I’ve have ever seen! Thanks for sharing your knowledge and for providing us DIYers an inexpensive creative alternative. Following your repair got my compressor back up and running…the fix cost me “zero cents” nothing. If you want to count rummaging though my sorted parts recycle bins still wouldn’t come close to the price of a repairman or replacing it with a new one. Thanks again you’re my RockStar! Cheers 🍻
This absolutely worked. I replaced the power cord, check valve and pressure switch and still nothing. I was just getting ready to use it for target practice before watching this. You are the man!
I wanted to thank you very much for this video. My motor end shroud has a small crack on the top but it was still seated fine. After replacing both the start and run capacitors, I was still tripping the breaker regularly on startup and when the compressor tried to repressurise at 120psi. Knowing the motor end shroud was seated properly, I turned my focus to the contactor assembly for the pressure switch that you mentioned. I sprayed some Deoxit D5 that I typically use for guitar and amplifier potentiometers on the contacts of the pressure switch and it not only started fine after that, but it also restarted as intended at 120psi. Not sure if this is a common problem or not but it certainly seems to have resolved my issue of regularly tripping breakers with this compressor.
@@je1279 I replaced the start capacitor but I couldn’t find the one with the right dimensions. It was close but my end cover is like the one in the video, tabs broken. Thanks for the reply.
Thank you so much for this video. I had the same exact problem with the same exact motor. Your video saved me from buying another compressor. I repaired my compressor just like you did yours. Everything is fantastic. Great Video. Thank you so much. My compressor is a Porter-Cable.
I was looking online pricing a new motor & come across ur video. The housing around the screw at the top was broken on mine causing the motor to hum. I didn’t get as fancy as u did but used some of that metal strapping with all the holes in it. Worked perfect. Thank u for the video. I owe u a beer.
Vid is solid frikken gold thank you. My free ‘side of the road’ $550 craftsman 30 gal is now fixed. Unfortunately I threw the shrouds away not knowing they were for more than just keeping fingers away from moving parts. Crap.
Had this exact problem with my 2004 made Craftsman model 919.168700. It got progressively worse for over a year and I couldn't figure it out. Tried different circuits, I knew the breaker wasn't the issue, nor was it anything in my garage wiring. Once I took the cover off (that was the toughest part...why these a-hole engineers use the dumbest type of screws in the dumbest places is beyond me)... I immediately saw the rear portion dislodged as you said, plastic pieces broken from nearly 15 years of wear and tear. I thought it was the capacitors for certain, but I saw that little pressure switch, and something told me to figure out what the heck that did. God bless TH-cam, it's saved me so much time and aggravation over the years. I used racing tape and replaced those worthless communist star screws with simple Phillips machine screws and boom! She runs like a clock once again. Thank you good sir!
Thank you! I recently bought the same air compressor in a very used condition. Worked at first but then was tripping the breaker without making a sound. I was ready to put the thing on the curb with a "free" sign when I came across your video showing the exact same condition. I was able to use JB Weld to glue the screw hole back on the top of that plastic piece and and fix a crack on the bottom. Problem solved!
I had the same issue today. I opened it and notice the lid was also broken just like you're video. I'm definitely going to use you're idea to make it a permanent fix. Thank you
Thanks for the video, I really appreciate it. Mine is the vertical version of yours and I think it is basically the same motor. The start capacitor busted and i put a new one in that was little bigger around and it did the same thing it was doing before which is just exactly what yours was doing. I think it was because i couldn't get the cover back on flush and mine has the screw tabs broken off also. Both my capacitors checked good so Im going to try what you have done. I didn't know how that switch worked behind the cover so thanks for the explanation. I put a new piston ring and head plate on it because one of the reed valves was broken and it ran fine for a while. Going to try this tomorrow. Thanks again.
Wow, thanks for that. My compressor has the exact same problem. Kept popping the circuit breaker could not figure it out. I was about ready. Throw it away.
Great fix idea thanks. I have the same problem with the vertical version 25 gal 5.5 hp. My dad bought this for me back in the '70's so I'd kind of like to keep it running.
I wanted to thank you! I just did my new cylinder and piston ring, well in the process I must have bumped the compositor. Started tripping n I was about to toss it (defeated) but luckily I found your video
pfun41...man....thank you for this video....i was thinking capacitor until or switch until i watched this. same issue....cheap plastic piece broke off that holds capacitor assembly snug....worked its way out....eventually wouldnt start. simply reassembled the capacitor assembly that i started taking apart...held it snug to the motor...boom...started. now to work on the repair. thanks again.
I had a similar problem. I would switch on the compressor and it only kinda half started, kinda like a car with a dying battery. I watched this video and opened it up, but all was good. I called my electrician and he said he thought it was a power company issue. I have overhead service and he said to call the electric co and have them come out to check for a corroded neutral at the pole since the neutral is usually not insulated. They came out and cleaned all three wires at the pole, but the problem persisted. I called them again and they cleaned the three wires at the house and that solved the problem. It was an Edison problem. So keep that in mind if you have this problem, or a similar issue with high power draw tools or appliances.
Thank you same issue on my craftsman model nbr 919.165070. The top and bottom plastic holds disintegrated over time and the compressor will not start and throws the breaker. Hold the cover on tightly and it starts perfectly. Brilliant! And the screws are star shaped torx - t20 seems to be the correct fit to remove the two covers.
@pfun41 - Like many other viewers leaving comments - I too was thinking I had a bad start capacitor. I have a craftsman compressor with a plastic cover holding the switch like yours and my cover broke as well. I used a strap like in your video. I would have never thought the broken plastic was the culprit but once I strapped it, and tried it, it works perfectly. Thanks to your video I saved money by not buying a new start capacitor, and saved time waiting for shipping of a new capacitor only to realize that was never my problem in the first place. Thanks for the heads-up!
Thanks for the video. Tried pressure switch, unloader valve, etc. Found out it was the plastic housing. Put a similar bracket in place to hold the housing and it now works fine. Thanks
OMG, thank you thank you thank you!!!!!! your video lead me to solving my compressor's issue that I've had for several years. While I could not make a bracket like yours some duct tape seems to have gotten it working for now.
Thank you, i have the same exact compressor and i was having this same problem, thank you again for explaining this and you saved me a lot of time. Excellent video
Thanks for the video! My plastic case broke and I’ve been trying to glue it. After seeing your video I like your idea! I also tried finding parts with no luck!!
Nice vid, I was hoping this was my problem...My Craftsman in this style is about 27 years old and built like a tank . The cover is metal and can't break. So back to square one.
When I get home it's on. Same thing going on with my upright unit. I bet that's it. Capacitors show good and I know the bottom part of the housing is broke but I have the piece and the screws. Maybe a little jb weld and it'll run again. Thanks.
Buddy you are the greatest and thanks for your video,I have a devilbliss air compressor that came with this same motor,I changed the both capacitors it worked a first run came back on,I was going to throw it away thanks man 👊🏽.I do straightening and painting and its a 30 gl works perfect for the job.THANKS AGAIN and I love your idea as mines dry rot also same place
I got one gave to me this week that won't start. I noticed the top cover bolt was broke out like that one, although it is a little different. I'll be checking this out tomorrow. Thanks for the heads up. If it works, I'll be sure and let you know.
This is better engineering than GE's. Think of it, my new MAC5200 Makita has to be teared apart to access the capacitors.... but this one won't separate from its motor cover all by itself ! Nice little compressor, though, easy to fix.
Can u tell me how the wires hook up to each capacitor? From motor & from cover. Looks like 2reds & brown to the run cap. & the 2 blacks to the start cap.? If u can help I'd appreciate it. Thx.
I have a very good question for you. Please help!! My older Sears Craftsman 220v 5 HP will not turn on unless the red reset button is pressed in and held in place. Any idea what this might be? Thank you David
In the manual it says to determine capacitor kit look on label under rear shroud. cant find this label but I am excited to see if my compressor works after I try putting the cover on like in your video TIA
Any way you can add the model numbers of your capacitors - i know one is 52A105185P1 which is the Mallory - trying to get the GE capacitor model number.
My compressor starts working and builds pressure up to 150psi but sometimes during work it will not start and won't keep tank charged. Sometimes it turns on only for a few seconds then goes quiet. Sometimes I hears something that it wants to start like air going somewhere through the pipe for about 2 second and then quiets and stays like that. Fails to keep up pressure in tank when I use it. Pressure goes low as 50psi but compressor doesn't start. Then I had to open drain valve to release remaining air pressure in the tank. Disconnect it from AC power for few minutes and it starts working again build up to 150psi again. I don't hear any air leaks. What could be wrong? How to fix it?
Thanks for the post.... Little different version but same exact issue on mine. Top mounting screw plastic on housing is busted. A little epoxy n we'll see.....
I opened mine to find that the cover was also broken. I suppose it was a design flaw of this GE motor after seeing how many other people had the exact same problem. Once I bolted it down, it attempted to run (even spinning for 3 seconds) before tripping the breaker. I suspect the Run Capacitor is bad because the Start Capacitor manages to get it running, then when the centrifugal switch kicks in, the Run Capacitor cannot maintain the load and trips the breaker.
Turns out both of my capacitors were good. It’s still tripping my breaker. Looks like I have a short circuit between the hot and the neutral. Any ideas what I should try?
I re-watched your video and noticed that my wires were crossed. Soon as I swapped the colors to match the ones on your capacitors, it started working. Thanks for this video! Just fixed my compressor!
Does anyone have any thoughts as to what could be causing the same startup/ trip breaker symptoms but with the cover not being broken? I tried replacing the start capacitor, it runs for a few seconds, and then shuts down.
Funny, they made two different types for that model then, you got Horizontal and I have the Vertical one from '04. The compressor has suited my needs over the years and has never been a problem, until about 2.5 weeks ago... The breaker threw when I was testing it out, the motor acted like it wanted to start, but then the breaker... So I took that whole back plastic cover to a shop and had the Capacitors checked. Well sure enough one wasn't working at full capacity. I replaced it, only problem is the new one is larger, so its mounted on top of the motor. The plastic shroud fits right over top like before. She's back up and running just like before! Here I posted the video I took after the Repair! th-cam.com/video/08TdvPnlJnE/w-d-xo.html
Does ur part have the number to it that is the issue I’m having I noticed it has a part number but it’s to hard to see the numbers. What would that cover be called
@@pfun41 I pick up another compressor it’s Devilbiss was talking to the guy and he recommended taking it to an electrician. Did ur compressor catch fire u said ? Enjoy ur Tuesday
Thanks for the video. I have the same one. I have to put a new run capacitor in mine but i dont have a wiring diagram. do you have any pictures of your? Thanks Craig.
Hey you just fixed my compressor. Been tripping breakers on and off for years. My motor is not exactly like yours but uses the same principle with the plastic having to be tight to the motor or the caps dont work right. I think I can rig something up similar to yours. Thanks
I have a Stanley 2 gallon tank air compressor. I went to use it real quick to air up my tire on my 2015 impala. The impala is a hole other problem. But the air compressor won't turn on when I plug it in. It worked fine not even 48 hours ago. Does anyone have any ideas for me on how to fix it. Cause I can't afford a new compressor.
i have an air copmressor of atlas copco company. i was working good but yesterday i changed fuel filter & engine oil filter and engine oil also after that when i try to star it is not working...it is giving a fualt(starter speed too low)..and RPM goes to 145 and go down slowly to 116 and triped...any solution please???
Theoretically an HVAC style starting circuit or even a hard start should work. But If the mechanicals for the existing starter circuit are intact it's easier to just repair this one than try to convert it.

Found the same problem on a horizontal model from 1996. Now functioning great again. Thanks for the tip!
I got the vertical model and got the same problem. Now I fix it after watching your video. Thank you so much.. You safe my money.
Thank you so much I have a upright one was having same issue. I epoxy the plastic and it worked for little bit failed again. This is a great idea.
Thank you! I recently bought the same air compressor in a very used condition. Worked at first but then was tripping the breaker without making a sound. I was ready to put the thing on the curb with a "free" sign when I came across your video showing the exact same condition. I was able to use JB Weld to glue the screw hole back on the top of that plastic piece and and fix a crack on the bottom. Problem solved!
I had the same issue today. I opened it and notice the lid was also broken just like you're video. I'm definitely going to use you're idea to make it a permanent fix. Thank you
Thanks for the video, I really appreciate it. Mine is the vertical version of yours and I think it is basically the same motor. The start capacitor busted and i put a new one in that was little bigger around and it did the same thing it was doing before which is just exactly what yours was doing. I think it was because i couldn't get the cover back on flush and mine has the screw tabs broken off also. Both my capacitors checked good so Im going to try what you have done. I didn't know how that switch worked behind the cover so thanks for the explanation. I put a new piston ring and head plate on it because one of the reed valves was broken and it ran fine for a while. Going to try this tomorrow. Thanks again.
Wow, thanks for that. My compressor has the exact same problem. Kept popping the circuit breaker could not figure it out. I was about ready. Throw it away.
Great fix idea thanks. I have the same problem with the vertical version 25 gal 5.5 hp. My dad bought this for me back in the '70's so I'd kind of like to keep it running.
I wanted to thank you! I just did my new cylinder and piston ring, well in the process I must have bumped the compositor. Started tripping n I was about to toss it (defeated) but luckily I found your video
Damn! Almost threw mine away. Thanks for this video, it was exactly what you were explaining.
pfun41...man....thank you for this video....i was thinking capacitor until or switch until i watched this. same issue....cheap plastic piece broke off that holds capacitor assembly snug....worked its way out....eventually wouldnt start. simply reassembled the capacitor assembly that i started taking apart...held it snug to the motor...boom...started. now to work on the repair. thanks again.
Thank you! I've been running into the same problem with mine. I'll be using this for mine. Been searching all over for that piece!
I had a similar problem. I would switch on the compressor and it only kinda half started, kinda like a car with a dying battery. I watched this video and opened it up, but all was good. I called my electrician and he said he thought it was a power company issue. I have overhead service and he said to call the electric co and have them come out to check for a corroded neutral at the pole since the neutral is usually not insulated. They came out and cleaned all three wires at the pole, but the problem persisted. I called them again and they cleaned the three wires at the house and that solved the problem. It was an Edison problem. So keep that in mind if you have this problem, or a similar issue with high power draw tools or appliances.
Thank you same issue on my craftsman model nbr 919.165070. The top and bottom plastic holds disintegrated over time and the compressor will not start and throws the breaker. Hold the cover on tightly and it starts perfectly. Brilliant! And the screws are star shaped torx - t20 seems to be the correct fit to remove the two covers.
@pfun41 - Like many other viewers leaving comments - I too was thinking I had a bad start capacitor. I have a craftsman compressor with a plastic cover holding the switch like yours and my cover broke as well. I used a strap like in your video. I would have never thought the broken plastic was the culprit but once I strapped it, and tried it, it works perfectly. Thanks to your video I saved money by not buying a new start capacitor, and saved time waiting for shipping of a new capacitor only to realize that was never my problem in the first place. Thanks for the heads-up!
Thanx, great video, by coincidence I have a 33 gal and a 25 gallon with the same symptoms and same basic design. I can't wait to dig into them.
Thanks for the video. Tried pressure switch, unloader valve, etc. Found out it was the plastic housing. Put a similar bracket in place to hold the housing and it now works fine. Thanks
OMG, thank you thank you thank you!!!!!! your video lead me to solving my compressor's issue that I've had for several years. While I could not make a bracket like yours some duct tape seems to have gotten it working for now.
Thank you, i have the same exact compressor and i was having this same problem, thank you again for explaining this and you saved me a lot of time. Excellent video
This was a huge help saved me tons of time Thank you
Yup time and money! I can keep my compressor and don't have to buy a new one!
Thanks for the video, my back cover was also broke and I was able to fix it with your video. Thanks!!
I suspect this is exactly the problem with mine. Thanks!
Thanks for the video! My plastic case broke and I’ve been trying to glue it. After seeing your video I like your idea! I also tried finding parts with no luck!!
Awesome video I believe that's what I wrong with mine. Thanks for sharing
Thank you for sharing. That was the exact problem with mine. It works again!
You totally save my compressor exactly what happened to it, thank you for the video👍 And I was gonna buy a new one😄
Nice vid, I was hoping this was my problem...My Craftsman in this style is about 27 years old and built like a tank . The cover is metal and can't break. So back to square one.
Hey thanks for the video. It helped me fixed my compressor today. Same problem.
When I get home it's on. Same thing going on with my upright unit. I bet that's it. Capacitors show good and I know the bottom part of the housing is broke but I have the piece and the screws. Maybe a little jb weld and it'll run again. Thanks.
This is the exact same problem with my air compressor! Thnx!!!
Buddy you are the greatest and thanks for your video,I have a devilbliss air compressor that came with this same motor,I changed the both capacitors it worked a first run came back on,I was going to throw it away thanks man 👊🏽.I do straightening and painting and its a 30 gl works perfect for the job.THANKS AGAIN and I love your idea as mines dry rot also same place
Men , you save me some good money . Thanks
I got one gave to me this week that won't start. I noticed the top cover bolt was broke out like that one, although it is a little different. I'll be checking this out tomorrow. Thanks for the heads up. If it works, I'll be sure and let you know.
This is better engineering than GE's.
Think of it, my new MAC5200 Makita has to be teared apart to access the capacitors.... but this one won't separate from its motor cover all by itself !
Nice little compressor, though, easy to fix.
Can u tell me how the wires hook up to each capacitor? From motor & from cover. Looks like 2reds & brown to the run cap. & the 2 blacks to the start cap.?
If u can help I'd appreciate it.
Thx.
I have a very good question for you. Please help!! My older Sears Craftsman 220v 5 HP will not turn on unless the red reset button is pressed in and held in place. Any idea what this might be?
Thank you David
In the manual it says to determine capacitor kit look on label under rear shroud. cant find this label but I am excited to see if my compressor works after I try putting the cover on like in your video TIA
IT WORKS !!! I was so excited heck I'm still excited today. Thank you Very Much for posting this video
Your orange ground wire is tore from the terminal on the start capacitor
This was almost the light at end of tunnel until I saw it was a train lol mine has similar symptoms but the cover was intact
Any way you can add the model numbers of your capacitors - i know one is 52A105185P1 which is the Mallory - trying to get the GE capacitor model number.
Duuuuuude. This fixed it. Thank you!!!
My compressor starts working and builds pressure up to 150psi but sometimes during work it will not start and won't keep tank charged. Sometimes it turns on only for a few seconds then goes quiet. Sometimes I hears something that it wants to start like air going somewhere through the pipe for about 2 second and then quiets and stays like that. Fails to keep up pressure in tank when I use it. Pressure goes low as 50psi but compressor doesn't start. Then I had to open drain valve to release remaining air pressure in the tank. Disconnect it from AC power for few minutes and it starts working again build up to 150psi again. I don't hear any air leaks. What could be wrong? How to fix it?
Thanks for the post.... Little different version but same exact issue on mine. Top mounting screw plastic on housing is busted. A little epoxy n we'll see.....
Heads up dealing with a problem with my 27 gallon craftsman but the compressor is identical to the 4.5 gallon porter cable air compressor.
I know this is an old video, but how does that centrifugal switch come off that shaft? Mine is broken and I need to replace it
I opened mine to find that the cover was also broken. I suppose it was a design flaw of this GE motor after seeing how many other people had the exact same problem. Once I bolted it down, it attempted to run (even spinning for 3 seconds) before tripping the breaker. I suspect the Run Capacitor is bad because the Start Capacitor manages to get it running, then when the centrifugal switch kicks in, the Run Capacitor cannot maintain the load and trips the breaker.
Turns out both of my capacitors were good. It’s still tripping my breaker. Looks like I have a short circuit between the hot and the neutral. Any ideas what I should try?
I re-watched your video and noticed that my wires were crossed. Soon as I swapped the colors to match the ones on your capacitors, it started working. Thanks for this video! Just fixed my compressor!
Does anyone have any thoughts as to what could be causing the same startup/ trip breaker symptoms but with the cover not being broken? I tried replacing the start capacitor, it runs for a few seconds, and then shuts down.
thats what my craftsman does . I will look for this issue.
Looking for the capacitors
Do you have pictures of the wiring have problems with mine getting it to turn on
I do not unfortunately.
Need info on125 psi, 1 HP, 3 gallon
Funny, they made two different types for that model then, you got Horizontal and I have the Vertical one from '04. The compressor has suited my needs over the years and has never been a problem, until about 2.5 weeks ago... The breaker threw when I was testing it out, the motor acted like it wanted to start, but then the breaker... So I took that whole back plastic cover to a shop and had the Capacitors checked. Well sure enough one wasn't working at full capacity. I replaced it, only problem is the new one is larger, so its mounted on top of the motor. The plastic shroud fits right over top like before. She's back up and running just like before! Here I posted the video I took after the Repair! th-cam.com/video/08TdvPnlJnE/w-d-xo.html
Can anyone tell me how the capacitor is wired in the red and brown side? Does it matter how they are hooked up or what prongs they go on??
It's AC so polarity doesn't matter.
Does ur part have the number to it that is the issue I’m having I noticed it has a part number but it’s to hard to see the numbers. What would that cover be called
They don't sell this part to my knowledge. And it's buried in the compressor housing in a shed now.
@@pfun41 I pick up another compressor it’s Devilbiss was talking to the guy and he recommended taking it to an electrician. Did ur compressor catch fire u said ? Enjoy ur Tuesday
@@peloneretana5924 No but the bearings recently locked up and fried the surge protector.
Thanks for the video. I have the same one. I have to put a new run capacitor in mine but i dont have a wiring diagram. do you have any pictures of your? Thanks Craig.
There's only 2 wires, hard to mess it up.
Hey you just fixed my compressor. Been tripping breakers on and off for years. My motor is not exactly like yours but uses the same principle with the plastic having to be tight to the motor or the caps dont work right. I think I can rig something up similar to yours. Thanks
Can you purchase the centrifugal switch ? I had the same issue as you had however the switch is bad.
I couldn't find any internal parts for this motor. It was a unique design ordered from GE by Craftsman for this compressor.
I know this is an old video but....I had same problem with my craftsman compressor,I used JB weld to reattach parts.so far still holding
I have a Stanley 2 gallon tank air compressor. I went to use it real quick to air up my tire on my 2015 impala. The impala is a hole other problem. But the air compressor won't turn on when I plug it in. It worked fine not even 48 hours ago. Does anyone have any ideas for me on how to fix it. Cause I can't afford a new compressor.
Ima try this I have the exact same one
i have an air copmressor of atlas copco company. i was working good but yesterday i changed fuel filter & engine oil filter and engine oil also after that when i try to star it is not working...it is giving a fualt(starter speed too low)..and RPM goes to 145 and go down slowly to 116 and triped...any solution please???
Sounds like something sticking in the compressor or the unloader stopped working.
Same thing I did, what about a generic startup thermistor type, and not use centrifugal, anyone know of??
Theoretically an HVAC style starting circuit or even a hard start should work. But If the mechanicals for the existing starter circuit are intact it's easier to just repair this one than try to convert it.
Same thing just happened to mine but even when I put the cover on it doesn't start
Could be a bad start capacitor, burned winding or centrifugal actuator.
where can I find the run capacitor for this compressor ? looking high and low

Hey did you ever find a compactor
Thank you!
