- Here's the basic explanation and example of how to replace and wire in a new pressure switch on an air compressor. I hope this is easier than watching a 20 minute video! I found it pretty basic and self-explanatory to do this, I hope that you do as well!
SMASH THAT LIKE BUTTON.

*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.*
Yes
I bought a used 60gal that had a broken off pressure switch that the guy had already just un-wired and thrown in the trash… so I had no reference and my Amazon unit had no labels or instructions. Replicated what yours looked like and got her running perfectly again! Thanks for such a clear and concise video with no crazy edits or stupid music. Well done my dude! 🤘🏻😎🤘🏻
That's great to hear! Thank you for that feedback, I appreciate it.
Straight to it! No cheesey background music and highschool gossip. I like your style!
Thanks man! I appreciate the feedback 🇺🇸🤘
you're tha goat ! i appreciate the information .
Thank you thank you! 🇺🇸🤘
Thanks for making it short and sweet and giving a good angle to pause the video at to refer back when you do it
Thank you for the kind words! I’m glad the video could help.
I'd rather leave it plugged in for the suspense and excitement.
That’d be a shocking surprise!

Great video. Short and sweet. Right to the point. Thank you Jimmy
Thanks Paul! I hope it was helpful.
Yes, now that someone who's competent has shown me what to look for n at, I can better troubleshoot my compressor issue. Thank you. Its been 2 weeks since I cant get the compressor to shut off when in use.
Sounds like it’s time for a new switch. Your diaphragm is likely toast. Best of luck! 🤘
Thank you. Very helpful and direct. One place I read said it took 45 min. To change so I thought it was very complicated. Your video showed me that it isn’t.
Thank you so much for the kind feedback. That’s exactly what my goal was for his video. I’m glad it could be a help to you. Thanks for watching 🤘
By the way the photography is excellent. I’m subscribing so please do more stuff.
@@Magnabee97 Thank you! I absolutely will, and I’m always open to suggestions.
Oh it’s going to take you every bit of the 45 minutes and then some.
Thank you!!! It was perfect and love the last line about being good to one another!!!
Gotta do it. Goodness makes the world go round 🇺🇸🤘 Thank you for watching.
I like to take a picture before disassembly. Sometimes there is a detail I need to look at later. Good video.
Robert Nicholson That’s a fantastic thing to do - I always take photos during the process.
Good idea!
Great short video!! And here comes the but. I wanted to see how the wires went through the new grommet.
Good point. If I could re-shoot it, I would have included that. Thank you for the positive criticism! 🇺🇸🤘
You are a good teacher
Thank you for the compliment. I hope this helps!
This will be a useful video for a long time.
I sure hope so!
did not show pressure adj, and don't say, comes adjusted...because if it does not come adj, i need to know what turn settings to do.
Great job ...thats what I was looking for I needed an explanation on the wiring on the switch
Glad this could help! Thank you f our watching 🤘🇺🇸
LOVE THIS VIDEO EXPLAINING COMPARE THE WIRING OF EACH SWITCH. I COULD NOT FIGURE IT.OUT
I’m glad it could help! 🇺🇸🤘
Well done! I like the short format
Thank you sir!
Thanks for the video just bought an air compressor for 80 bucks and needed one of these switches bought an oem one because I was kinda skeptical about these cheaper ones hopefully this compressor should last me for a long wile
I’m glad to have helped! Best of luck with your new machine 🇺🇸🤘
That was great. No wasted words!
That’s the goal! Thank you for watching 🤘🏻🇺🇸
Thanks for simplifying this.
I’m glad it was helpful! Best of luck with your project.
Jimmy's I like it right to the point simple and easy keep them coming.
Thanks man, I appreciate it. That's exactly what I was aiming for.
thank you for the really clear video on this replacement process; very easy to understand; please continue bringing clear and useful videos,' I for one need them; PJP
You are very welcome! Thank you for watching 🇺🇸🤘
Nice video mate , very simple and easy to follow ! Now how would i take the existing wiring and mount an external switch for the air compressor silencer box I’m building? I’ve got the extension air dump valve line sorted , and the airline connectors , but want to do this part safely. I could always fabricate something that locks on to the stop start button using a pull rod (either way I’m going to have to drill a hole) but would prefer a big red emergency stop button . If I use the current switch it will have no means of an earth , and I don’t want to expose the housing where it normally sits. Interested in hearing your thoughts ?!
Thanks mate 😊
It sounds like you’re on a good track my man. I usually don’t do modifications like that - I’m more of a resto-mod kind of guy. I like to keep it simple; clean and re-tap the threads, new regulator & fittings and new drain valve. That’s my jam. Best of luck to you with your project! Thank you for watching 🇺🇸🤘
Simple and useful. Thanks
Thank you sir! 🇺🇸🤘
Excelente Producto
Thank you! 🇺🇸🤘
Remember line is from your breaker box or wall receptacle and load is the wiring going to a motor in this case or other device that uses the electricity. Think of power lines and that is where line comes from and your device creates a load so it is referred to as the load.
Great advice!
Great video
Thank you Tim! 🇺🇸🤘
Thank you!
Thank you for watching 🇺🇸
Hey thanks for the video I just bought this as well used but I have no idea how to use it can you show a video explaining how to adjust the air tool regulator because mine doesn't even turn on but the tank does
Hello! I sold that machine shortly after this video was done - it was a flip project. If you’re having issues - try to find a manual online. Regulators typically increase pressure when turned clockwise, and decrease counter clockwise. I know that’s not much help. Best of luck to you! 🇺🇸🤘
Thank you Jimmy.....................
I hope it helped. Thank you for watching! 🤘🏻🇺🇸
Great simple video, my compressor kids on then off then on then off. You think it’s the pressure switch?
100%. Your pressure switch has a diaphragm that lifts up when the tank reaches cutoff/cut in pressures. It then pushes/releases a metal contact that turns the pump on and off. Yours is shot. Easy fix!
@@jimmysgarage9068 replaced pressure switch. Still does the same thing on then off on then off. You think the mother is shot?? I’d a Coleman powermate 27 Gallon. Can’t find and parts anywhere for it.
@@WWard1962 I haven’t personally worked on a Coleman machine. The pressure switch controls the on/off due to pressure in the tank pressing on the diaphragm. So either you have a bad/wrong (new) switch.
Have you emptied the tank of moisture? Make sure that it’s always emptied of water/condensation. You may have a blockage in the fitting connected to the pressure switch due to rust?
Hard to really say without helping you tear into it.
@@jimmysgarage9068 thanks again. Bough the same switch you used. I will keep trouble shooting. Hate to trash the compressor.
Thanks for keeping it short. I waist way to much time filtering though the useless info.
Hey YOU'RE A SEABEE! I WAS A UTILITIESMAN
Hey UT! Former CM2 here. Hoorah Bees 🇺🇸🤘
Awesome
Thanks dude
Thank you for watching 🇺🇸🤘
Love it
Thank you

I have a 20 gallon air compressor which is 120v....can I turn it into 220v from switching over the wire???
Only if the motor is rated for 220.
On this episode of Jimmy's garage...Jimmy is under pressure to fix another old compressor. He tries to simplify the instructions for his huge fan-base so they don't experience shocking results. Stay tuned to see if the subscriber base swells or fries.
You are a maestro of words.
My white is on the left and black on the right. Green is the same? Why is it different?
I’d have to see your specific machine.
i should have watched before i worked on it, i was trying to fix the switch, where do you get the replacement switch
I got mine on eBay. Less than $20.
Which wires are power and nuetral (black and white)? My switch is labeled N/P. Also, on the motor end connections, which wires go where on the starter solenoid and temp protection switch? I can't find a video on how those are connected.
Black is hot - white is neutral. As far as the motor - try to find a manual online for the specific model/make/brand. Best of luck!
@@jimmysgarage9068 Thanks!
Do all compressors have a pressure switch? I own a light 2 gal Mastercraft compressor that had a cracked manifold… so I decided to try and fix it by doing the following : at the output of the tank, I installed a regulator with gauge, followed by a Y fitting, on one side I have the safety valve, and on the other side, my tool plug. The compressor build up pressure to about 120 PSI (it’s rated at 125 PSI max), and stops by jtself… So there must be some kind of mechanism that tells it to stop? I just tried to reproduce the original manifold assuming the big knob was just a regular air regulator…
Short answer - yes. If they didn't have a way to regulate max tank pressure, the motors would run until they wear out. Also, the max PSI of a machine isn't always reflective of the tank, but of the motor's capability of continually building pressure in said tank.
You'll notice with some air compressor brands, they'll have a few different sized tanks, but all with the same motor. That's because the motor can only push air into a tank with 135/150/175 PSI until it can't anymore.
I hope that makes sense! Thank you for watching.
What is the function of red lever arm on the switch
On/off
Also question 34 oz of oil I'm told that goes in this but that's over 1,000 ML and a psycho and a sight glass is full and it's only supposed to be two thirds full so how many ounces of oil does this take
Good question. Rule of thumb is the middle of the sight glass. Fill it to that point, run it for a few minutes and then let it rest. If you need to add more - you can. Definitely don’t overfill. 🇺🇸🤘
@@jimmysgarage9068 thank you so much
On my Sears 4 HP 20 gal. compressor ( over 40 years old ) , the markings on the screw terminals are different than the MOTOR / LINE on yours. Both line screw terms are on the side closest the cord inserts Go figure....error or design change ?
Sounds like a different design to me! Always interesting to tear old machines apart to see how they made them.
Sorry what's the point of restoring these ? Aren't horizontal tanks notorious for rust. Which just makes these things more likely to blow up?
If they’re drained properly and the tanks don’t have any signs of internal rust, they can have a good life span.
I have a horizontal 20 gal. tank compressor which is over 35 years old. I have it on a slight angle ( wooden block under the piston end ) giving a slight incline so that any condensation runs toward the tank drain which is on the tank BOTTON towards the handle side. I sometimes open the drain valve just a slight bit so that as the unit runs, the water is blown out the petcock and doesn't collect.
@@jameskrivitsky9715 great idea. i found a tank it's rusted to death.. it's a goner.
Hi Sir, my oil-less air compressor doesnt have a small airline tube. All of the replacement switches i saw on the web has. Should I decide to use those, will it still work even if I dont have the airline?
I’d try to find an exact match to yours.
I like short, but I need to know what the red thread tape is called?
Not sure what you mean…
@@jimmysgarage9068 Short is how I like instructional videos. There was red tape on the brass fitting of the new pressure switch, most likely a heat resistant tefon. Sorry for the confusion.
You forgot the most important step if you don't want to die. Empty the tank of pressure before you remove the switch. Whew
Great point! 🤘
How it goes is a second video ?
I sold that machine shortly after finishing the restoration. I can assure you that It worked perfectly. Thank you for watching 🤘
Actually you pointed to the wrong locations of motor/line on your new one. Just saying
380 volt ?
Not quite!
Are you sure about the white and Black. Because Neutral(white) is on the left side in any receptacle? Trace your power line from the plug. With the ground down you'll find that the White is on the left. It will run regsrdlessly. Could be the reason the other switch was defective. That was not a factory wiring job. I am pretty sure You copied a mistake. Please be care when giving instructions with so much confidence. Some could get hurt. Maybe better to say “I think and disqualify yourself as an expert. Other than that great job
👍
No volume
Must be something wrong on your end.
Or… you can just order the correct switch for the machine… that way everything IS the same.
That too! Thanks for watching 🤘🇺🇸
It's depends on if they even make the original part. I inherited a Campbell Hausfield that's leaking from the pressure switch. Probably made in the 90's.
You can no longer get the original switch even from the manufacturer. They sell a replacement part for it but it's as different from the original as the one in the video is.
Definitely make sure the pressure rating is correct for your compressor. It seems like lots of new compressors are rated higher than my compressor.
not smashing like button, because you did not show how to adjust the pressure screws on new switch
Understood. I can make a video on that if it helps! Thank you for watching 🇺🇸🤘🏻
