One of the best video and instructions on the subject. Very clear and delivery is near perfect. you are a good teacher. God bless you for transferring the knowledge to people who need it. This provides detailed instructions and confidence to home owners to trouble shot and fix their AC problems with out being taken advantage by not so honest repair people or sales personnel that usually push for replacing the unit prematurely. Thank you for your service.
@@electronicsNmore Sure, will do. Again, knowing is one thing, but being able to communicate with others is a different story. You have been blessed with that gift. Being a Yoga teacher, I can recognize a dedicated teacher when I see one.
Your video is one of the best DIY I ever seen - use of screen shots, closeups, extra resources. Plus you explain things in a fashion that I can understand and I am not an electrician. Thank you!
This is one of the best videos I've seen on this topic. Not many other videos are going to mention banging on the compressor with a rubber mallet and the hard-start kit. Very comprehensive. The only thing you didn't mention is that turning the fan with your screwdriver like that will sometimes get the fan started in a pinch.
I have gone to an AC class in the community college but the information I got in 3 months is not as productive as what I've seen. It's very informative, clear, and cut to the chase. Thank you very much.

Stumbled upon your video while searching for AC troubleshooting tips. Your instructions are quite comprehensive and with enough details to allow even the beginners such as myself start learning how to troubleshoot AC problems. Unfortunately, because I don't have the right tools or know how, my skill levels stopped at changing the capacitors of the outdoor unit that still won't start :( will be calling a service professional and most likely shedding some $$. I still find your video very instructional at understading what each component does. Thank You !

I was 99% percent certain that there was an issue with my condenser fan because the fan was hot to the touch but it wasn’t spinning. Thank you for this vid
A hot condenser fan motor that's not spinning is either a bad capacitor, faulty bearing causing the fan to stick, or a bad winding in the fan motor. Thanks for watching!
This is a really good video of how to. I used your steps to troubleshoot the AC issue I was having... somehow, i had turned off the power to the AC why attending to water leakage in the attic few days back. So after watching your video on two or three occasions, I troubleshooted on the unit using the steps and it led me to the AC power source that I never knew of it function in the attic. No repair, no parts needed just put back the switch on! This event also given me the opportunity of cleaning the evaporator section which has been causing terrible odour coming from the AC for a while now. That saves us a lot, we almost resulted to calling professional to fix the issues. Thanks a lot Just to add though, all units are not the same, my thermostat is OLD, it is electro-mechanical using mercury for contact switch and the attic AC uses Gas for heating; the outside compressor uses a booster capacitor alongd with one small main capacitor looking rusty, and the power source from the wall to the unit is connected with no fuse in place. This is how we got the house, knew nothing about AC connection before now. Good tutor, thanks.

Excellent tutorial for learning basic home units. If you have some engineering training from college,, this video shows the important practical ways to diagnose and repair a system. Perfect amount of troubleshooting without all the more technical aspects of electrical engineering or thermodynamics of a cooling system.Thank you for the work done on explaining things simply but thoroughly.
Thank you VERY much for the donation to support my channel. I could count the donations I received from this video on one hand. Sadly most people expect others to produce videos like this for them(saving them big bucks), but they rarely give back. Most people are cheap.
Well as a woman i am learning.. The air conditioner was on cool but blowing warm air .i went outside and felt the air coming out of the fan it was cool..not warm.. Then checked batteries in thermostat..put in new ones..turned it to off..waited a few mins turned on and it started blowing out cool air inside the house..went outside and the fan was blowing out hot air as you said it should ..thanks as now it is cooling off inside.. Now i may purchase a new thermostat.. As i called my air cind. Service for a check up and everything was fine in May.. ?? But right now it is cool!! Thank you for the info
Hands down the best troubleshooting video I've seen. You did a great job at going through the troubleshooting tree but unfortunately you stopped right before my issue. Compressor and fan running but no cold air. I was hoping you'd cover the reversing value and manifold set.
@@electronicsNmore yes, I have a heat pump. Trane XR15. I wish I had seen your video before I started looking at it. I would have saved a lot of time. Very clear and concise. I appreciate your effort (paypal'd). I'm a EE so I just looked at the circuit diagrams and traced it out. I've seen other people mention the reversing value sticking but haven't had time to look at diagnosing that but I would think that if it was stuck the system would be blowing heat which it's not. Just blowing temped air. I also don't think it's the value because I never use the heat pump. Gas is cheaper. I wasn't sure if there is anything else I can look at. I was thinking of buying a manifold set but I don't know the pressures and if refrigerant is the issue I couldn't buy it because I don't have a license but it's still gnawing at me because I like solving problems.
That was very kind of you to send that Paypal donation, it's much appreciated. Is the compressor working? Do any of the refrigerant lines feel cool or cold to the touch? Any show condensation on them? With the system powered off, and after waiting a few minutes for the pressure to equalize in the lines, you can try applying 24V-27VAC directly to the reversing valve to see if you hear the solenoid make a click sound. It's possible that your solenoid uses a higher voltage than 24-27vac. You should buy a manifold gauge set at Harbor Freight, they're good to have and can help you diagnose problems. It sounds like you have low refrigerant. If you have more questions, just ask. Thanks!
@@electronicsNmore thanks, I just typed up a long list of everything I tested in which I determined the compressor was not running. I went back to the unit to check one thing and saw the issue. A very obvious issue (I'm glad I removed the fan housing). One of the legs to the compressor was not routed through its hole, instead it was between the sheet metal and fan housing. The sheet metal had cut through the insulation melting a nice hole in the metal. The install was 7 years ago so I doubt going back to the installer would help. What's the recommenced fix? It's 12awg. I just used a butt splice. Trane should have used a grommet.

Very informative! My unit quit working outside I have someone coming Saturday. At least I can understand when they try to repair and whether or not they’re trying to sell me a bunch of lies.
My AC recently stopped working. I watched this and got some good tips. The blower would not come on or the compressor outside. I have a gas air handler. When it quit the refrigerant line froze up. So I checked it for power. Good to go. I took the cover off the compressor outside and pushed in the switch. It came on. So then I went inside and checked the blower motor. I checked to see if it turned. It did. I could hear refrigerant circulating., but it would not come on. When the thermostat was on, I carefully felt the motor. It was warm. So I suspected the capacitor. I took it out which took about 2 minutes. Put a new one in and it cranked right up! One $10 part did the trick. Now I am going to keep a spare capacitor at home.

You are such a great teacher! Thanks so much for clear concise video that walks viewers like me through all the steps from the thermostat to knocking on the compressor with a rubber mallet 🙂. In my case, my blower fan ran, the condenser fan ran, the compressor ran (but louder than usual), but the air blowing out registers in the house was not cool. I noticed at the condenser unit outside the air blowing out on top was not warm, and the suction line was sweating a little, no icing on it. Wonder what else would be the problem with it?
@@electronicsNmore Thank you for the suggestion. Few days before the air coming out of registers was less cool, then the next evening the AC ran all night but no cool air at all. The line pressure may be low as you suspect? And it may have a leak then. But I don’t have gauge to check. Will need to invest in one..

Great video and explanation. My condenser and fan both stopped while the air handler is still running. Yesterday I opened the outdoor unit and visually inspected wiring and capacitors, turned power back on and it worked again. Ran fine for 24 hours and now they both shut off again. Will start with power verification but weird that both are not on.

Very informational! I have very limited electrical skills and no A/C skills but your tutorial helped me fix my A/C.

Always go to thermostat first. turn fan auto switch from auto to fan on . if blower comes on this will tell you that there is 240 volt and 24 volts present at air handler, this will tell you complete blower motor circuit is functional and that transformer ,fan relay board is functional. if you remove front of thermostat and jump out low voltage from red 24 volt hot to yellow cool and do not keep a good contact on terminals you stand a good chance on overloading compressor from multiple starts putting compressor in a bind and causing compressor failures unless there is a time delay at condensing unit. most standard units use compressor time delay from digital thermostat. condenser unit and evaporator coil have same size tubing it is the metering device or expansion valve that changes refrigerant from hot liquid to cold gas then heat from house can be absorbed and removed by condenser fan to outside air. always make sure to clean drain line well and condenser coils while there. also if 24 volt is lost check fan relay board fuse and or fuse on transformer. make sure your attic is very well ventilated this can save customer 25 percent on light bill.and avoid profuse sweating of duct work.
Thanks for the step by step trouble shooting for the complete system with tips on what can and typically be not working at each step with enough theory on how/why it all works.

Absolutely the best a/c troubleshooting video!!! Great job!!! I have a trane xi19.... 2 stage system. The two run capacitors are only for compressors. How does the condenser fan turn on? Direct connection from contactor?
Glad you liked the video! Sadly there are many videos that don't come close to mine, and they have far more views. Too many people watch, but they don't take 1 minute to share the video link. When the contactor closes, the fan turns on. Thanks for watching!
@@electronicsNmore thanks...I for one greatly appreciate the depth of your videos ...will share with others. BTW...Fan does not come on with either stage 1 or 2 compressor contactors...seems to me it must be the control board at the condenser that turns on the fan....what do u think?
Wow. Really fantastic and professional job relating this substantial technical material. You must be sponsored by a TV station or AC manufacturer.

Excellent video.. Personally I would like to see this industry get it's act together with wiring. Nix the wire nuts and provide a terminal strip for low and high voltage as needed inside and out. Sloppy electrical that needs to be cleaned up. Never understood why they do what they do and it can cause issues with poor wire management.
Thanks for the great video! I have one question, what would cause the fan to start then stop after about a minute? That's what mine did and when I immediately tried to spin it after it stopped, it was stuck/ seized. However, when I turned the unit off and tried to spin the fan it spun without resistance. BTW, I just replaced the run capacitor as well.
Corrections: 15:08: When the *float* is in the down position [you'll have continuity]. 21:00: Measure the resistance across the blower motor's *start/run? winding*.
What are you talking about? LOL There are no corrections. I suggest you play the video again. Float DOWN = no water buildup/continuity, Float UP = water buildup/no continuity. As for 21:00, worded just fine.
@@electronicsNmore It says when the switch, not float, is down. Kind of confusing. And at 21:00 it says across the blower motor's capacitor, not windings. I think we've already checked the capacitor and now we're checking the windings, right?
@@electronicsNmore Well, maybe I'm picking nits, but I don't think we really know whether the float switch itself is, physically, up or down, only the actual float. Right?
Thank you thank you thank you! It's 90 degrees at least here and I went all the way to smacking the compressor with the rubber mallet. Walla! She lives!

Awesome! Thanks! My capacitor went out on my outdoor compressor/condenser last summer, twice. The first one I put in was just the closest I could find that day it ended up going out a week later but at that point I have a proper one. Its was stupid of me to do that since it controls the fan but thankfully both times it went out I was sitting at my desk and my condenser is just outside my window so I head it go out. I am just glad I was here, if I wasn't I could have easily burnt up the unit. Or at least I assume I could have. I don't know if this thing has a thermal fuse or anything.

Thanks electronicsNmore! I searched through a ton of videos, I found this to be one of the best, and more comprehensive step-by-step instructions on how to diagnose HVAC issue, especially if you are attempting this for the first time. I am a subscriber now. I do have one diagnosis question, which perhaps you can include in your instruction. If the AC is blowing hot air in the vents, but the return side (pipe) of the Air Handler is very cold, does that imply that the Compressor unit in the Condenser outside is working? Thanks!
Jay Shah If the larger pipe (lower pressure suction line) is covered in frost, and the air handler blower motor is working, then you're low on freon. Make sure the heat isn't on while the system is cooling. Thanks for subscribing. Be sure to rate thumbs up and share.
My AC just crapped out and watching this i realized ill have to fork over the $250/hour to get a pro to look at. Looking at you individually manually diagnosing every single sub system makes me wish these systems were self monitoring, and had an instrument panel on the main unit with green lights for each and every sub system that went red when and if they failed.
excellent video I got 270v on the top terminals, I assume some of the voltage is coming from the capacitor, shouldn't you also have gotten higher than 240?
Thanks Chris! Be sure to check out my extensive video playlists below for many other videos of interest to you, and most importantly share. th-cam.com/users/electronicsnmoreplaylists
thanks for the video! I have a goodman AC unit, 2 years old. It was not blowing cold air. The fan on the unit was on but there was not the familiar buzz of when the compressor is running. I turned everything off, opened the panel. I just wiggled the wires on top of the capacitor. They were not loose but thats all I did. when i turned everything back on, there was not cold air at first, but a few minutes later, cold air was blowing and the outside unit was buzzing with the sound of the compressor. Its been working fine overnight. My question is, should I just change the capacitor anyway or could it be an issue with the compressor itself? how do I figure that out? thanks!

Love this video I'm stumped.my ac isn't running,I had a ac guy out to my home and he said it was the condenser motor an needed a hard start. I changed hard start but then I saw your video. I did your method of pushing in the contactor and it runs while pressed but when I let go it cuts off, I did it twice and the first time the contactor stayed pressed but after a minute it shut off but now it wont stay pressed Could motor be the cause, he says the fan could be over heating.
@@electronicsNmore thanks for the reply, so I last night the ac worked all night but when I turned it on during the day it shut down completely again. I think I jumped the thermostat and still nothing. Thermostat has g,y,w,rh,rc, how would you jump that? I'm get cold air when I press the contactor in still. Fan in the attic is running still so I believe the board is good. Thinking I'll replace the contactor next, which letter do you jump to the rc screw?
Good video. Question: I have a 1.5ton 220 volts split unit AC. After few seconds of turning it on, the clamp meter reads 22 A then rise to reach 37 A for few seconds then it stops and the clamp meter reads zero or 0.1 A. What could be the problem ?

Stumbled upon your video while searching for AC troubleshooting tips. Your instructions are quite comprehensive and with enough details to allow even the beginners such as myself start learning how to troubleshoot AC problems. Unfortunately, because I don't have the right tools or know how, my skill levels stopped at changing the capacitors of the outdoor unit that still won't start :( will be calling a service professional and most likely shedding some $$. I still find your video very instructional at understading what each component does. Thank You !

I was 99% percent certain that there was an issue with my condenser fan because the fan was hot to the touch but it wasn’t spinning. Thank you for this vid
A hot condenser fan motor that's not spinning is either a bad capacitor, faulty bearing causing the fan to stick, or a bad winding in the fan motor. Thanks for watching!
This is a really good video of how to. I used your steps to troubleshoot the AC issue I was having... somehow, i had turned off the power to the AC why attending to water leakage in the attic few days back. So after watching your video on two or three occasions, I troubleshooted on the unit using the steps and it led me to the AC power source that I never knew of it function in the attic. No repair, no parts needed just put back the switch on! This event also given me the opportunity of cleaning the evaporator section which has been causing terrible odour coming from the AC for a while now. That saves us a lot, we almost resulted to calling professional to fix the issues. Thanks a lot
Just to add though, all units are not the same, my thermostat is OLD, it is electro-mechanical using mercury for contact switch and the attic AC uses Gas for heating; the outside compressor uses a booster capacitor alongd with one small main capacitor looking rusty, and the power source from the wall to the unit is connected with no fuse in place. This is how we got the house, knew nothing about AC connection before now. Good tutor, thanks.

Excellent tutorial for learning basic home units. If you have some engineering training from college,, this video shows the important practical ways to diagnose and repair a system. Perfect amount of troubleshooting without all the more technical aspects of electrical engineering or thermodynamics of a cooling system.Thank you for the work done on explaining things simply but thoroughly.
Thanks Ed!
You sir, are an excellent instructor and video producer. Thank you very much. I sent you $20 to show my appreciation. You saved me a whole lot more.
Thank you VERY much for the donation to support my channel. I could count the donations I received from this video on one hand. Sadly most people expect others to produce videos like this for them(saving them big bucks), but they rarely give back. Most people are cheap.
Well as a woman i am learning.. The air conditioner was on cool but blowing warm air .i went outside and felt the air coming out of the fan it was cool..not warm.. Then checked batteries in thermostat..put in new ones..turned it to off..waited a few mins turned on and it started blowing out cool air inside the house..went outside and the fan was blowing out hot air as you said it should ..thanks as now it is cooling off inside.. Now i may purchase a new thermostat.. As i called my air cind. Service for a check up and everything was fine in May.. ?? But right now it is cool!! Thank you for the info
I will sleep on what steps i need to take now..
Its still cooling!! Whew happy it is!!

Hands down the best troubleshooting video I've seen. You did a great job at going through the troubleshooting tree but unfortunately you stopped right before my issue. Compressor and fan running but no cold air. I was hoping you'd cover the reversing value and manifold set.
Thanks Bill! Do you have a heat pump system?
@@electronicsNmore yes, I have a heat pump. Trane XR15. I wish I had seen your video before I started looking at it. I would have saved a lot of time. Very clear and concise. I appreciate your effort (paypal'd). I'm a EE so I just looked at the circuit diagrams and traced it out. I've seen other people mention the reversing value sticking but haven't had time to look at diagnosing that but I would think that if it was stuck the system would be blowing heat which it's not. Just blowing temped air. I also don't think it's the value because I never use the heat pump. Gas is cheaper.
I wasn't sure if there is anything else I can look at. I was thinking of buying a manifold set but I don't know the pressures and if refrigerant is the issue I couldn't buy it because I don't have a license but it's still gnawing at me because I like solving problems.
That was very kind of you to send that Paypal donation, it's much appreciated. Is the compressor working? Do any of the refrigerant lines feel cool or cold to the touch? Any show condensation on them? With the system powered off, and after waiting a few minutes for the pressure to equalize in the lines, you can try applying 24V-27VAC directly to the reversing valve to see if you hear the solenoid make a click sound. It's possible that your solenoid uses a higher voltage than 24-27vac. You should buy a manifold gauge set at Harbor Freight, they're good to have and can help you diagnose problems. It sounds like you have low refrigerant. If you have more questions, just ask. Thanks!
@@electronicsNmore thanks, I just typed up a long list of everything I tested in which I determined the compressor was not running. I went back to the unit to check one thing and saw the issue. A very obvious issue (I'm glad I removed the fan housing). One of the legs to the compressor was not routed through its hole, instead it was between the sheet metal and fan housing. The sheet metal had cut through the insulation melting a nice hole in the metal. The install was 7 years ago so I doubt going back to the installer would help.
What's the recommenced fix? It's 12awg. I just used a butt splice. Trane should have used a grommet.
Thanks. Your explanation helped me fix it myself.

Very informative! My unit quit working outside I have someone coming Saturday. At least I can understand when they try to repair and whether or not they’re trying to sell me a bunch of lies.
Good luck!
My AC recently stopped working. I watched this and got some good tips. The blower would not come on or the compressor outside. I have a gas air handler. When it quit the refrigerant line froze up. So I checked it for power. Good to go. I took the cover off the compressor outside and pushed in the switch. It came on. So then I went inside and checked the blower motor. I checked to see if it turned. It did. I could hear refrigerant circulating., but it would not come on. When the thermostat was on, I carefully felt the motor. It was warm. So I suspected the capacitor. I took it out which took about 2 minutes. Put a new one in and it cranked right up! One $10 part did the trick. Now I am going to keep a spare capacitor at home.

You are such a great teacher! Thanks so much for clear concise video that walks viewers like me through all the steps from the thermostat to knocking on the compressor with a rubber mallet 🙂.
In my case, my blower fan ran, the condenser fan ran, the compressor ran (but louder than usual), but the air blowing out registers in the house was not cool. I noticed at the condenser unit outside the air blowing out on top was not warm, and the suction line was sweating a little, no icing on it. Wonder what else would be the problem with it?
In your case I would need to look at a manifold gauge to observe the pressures.
@@electronicsNmore Thank you for the suggestion. Few days before the air coming out of registers was less cool, then the next evening the AC ran all night but no cool air at all. The line pressure may be low as you suspect? And it may have a leak then. But I don’t have gauge to check. Will need to invest in one..

Great video and explanation. My condenser and fan both stopped while the air handler is still running. Yesterday I opened the outdoor unit and visually inspected wiring and capacitors, turned power back on and it worked again. Ran fine for 24 hours and now they both shut off again. Will start with power verification but weird that both are not on.
When it stops working, you need to make sure the contactor is triggered and that you have 240V. Could be the compressor overheating.

Always go to thermostat first. turn fan auto switch from auto to fan on . if blower comes on this will tell you that there is 240 volt and 24 volts present at air handler, this will tell you
complete blower motor circuit is functional and that transformer ,fan relay board is functional. if you remove front of thermostat and jump out low voltage from red 24 volt hot to yellow cool and do not keep a good contact on terminals you stand a good chance on overloading compressor from multiple starts putting compressor in a bind and causing compressor failures unless there is a time delay at condensing unit. most standard units use compressor time delay from digital thermostat. condenser unit and evaporator coil have same size tubing it is the metering device or expansion valve that changes refrigerant from hot liquid to cold gas then heat from house can be absorbed and removed by condenser fan to outside air. always make sure to clean drain line well and condenser coils while there. also if 24 volt is lost check fan relay board fuse and or fuse on transformer. make sure your attic is very well ventilated this can save customer 25 percent on light bill.and avoid profuse sweating of duct work.

Excellent video.. Personally I would like to see this industry get it's act together with wiring. Nix the wire nuts and provide a terminal strip for low and high voltage as needed inside and out. Sloppy electrical that needs to be cleaned up. Never understood why they do what they do and it can cause issues with poor wire management.
Glad you liked the video. I agree, fortunately some newer units have terminal strips.
Fantastic Video- After watching, within 5 minutes, I found my problem! Thank you!!
Thanks for the great video! I have one question, what would cause the fan to start then stop after about a minute? That's what mine did and when I immediately tried to spin it after it stopped, it was stuck/ seized. However, when I turned the unit off and tried to spin the fan it spun without resistance.
BTW, I just replaced the run capacitor as well.
Faulty fan motor.
@@electronicsNmore I really appreciate you for getting back at me within 24hrs! Thank you 🙏🏻
Corrections:
15:08: When the *float* is in the down position [you'll have continuity].
21:00: Measure the resistance across the blower motor's *start/run? winding*.
What are you talking about? LOL There are no corrections. I suggest you play the video again. Float DOWN = no water buildup/continuity, Float UP = water buildup/no continuity. As for 21:00, worded just fine.
@@electronicsNmore It says when the switch, not float, is down. Kind of confusing. And at 21:00 it says across the blower motor's capacitor, not windings. I think we've already checked the capacitor and now we're checking the windings, right?
@@tmst2199 Float SWITCH
@@electronicsNmore Well, maybe I'm picking nits, but I don't think we really know whether the float switch itself is, physically, up or down, only the actual float. Right?

Awesome! Thanks! My capacitor went out on my outdoor compressor/condenser last summer, twice. The first one I put in was just the closest I could find that day it ended up going out a week later but at that point I have a proper one. Its was stupid of me to do that since it controls the fan but thankfully both times it went out I was sitting at my desk and my condenser is just outside my window so I head it go out. I am just glad I was here, if I wasn't I could have easily burnt up the unit. Or at least I assume I could have. I don't know if this thing has a thermal fuse or anything.

4:00: 28V to thermostat. Connecting red to green turns on blower. Yellow throws in the compressor.
28V is fine.
Thanks electronicsNmore! I searched through a ton of videos, I found this to be one of the best, and more comprehensive step-by-step instructions on how to diagnose HVAC issue, especially if you are attempting this for the first time. I am a subscriber now. I do have one diagnosis question, which perhaps you can include in your instruction. If the AC is blowing hot air in the vents, but the return side (pipe) of the Air Handler is very cold, does that imply that the Compressor unit in the Condenser outside is working? Thanks!
Jay Shah If the larger pipe (lower pressure suction line) is covered in frost, and the air handler blower motor is working, then you're low on freon. Make sure the heat isn't on while the system is cooling. Thanks for subscribing. Be sure to rate thumbs up and share.

My AC just crapped out and watching this i realized ill have to fork over the $250/hour to get a pro to look at. Looking at you individually manually diagnosing every single sub system makes me wish these systems were self monitoring, and had an instrument panel on the main unit with green lights for each and every sub system that went red when and if they failed.
Thanks for watching!
excellent video
I got 270v on the top terminals, I assume some of the voltage is coming from the capacitor, shouldn't you also have gotten higher than 240?
Keith Haworth Check the voltage entering the unit and compare.
entering voltage is 240

thanks for the video! I have a goodman AC unit, 2 years old. It was not blowing cold air. The fan on the unit was on but there was not the familiar buzz of when the compressor is running. I turned everything off, opened the panel. I just wiggled the wires on top of the capacitor. They were not loose but thats all I did. when i turned everything back on, there was not cold air at first, but a few minutes later, cold air was blowing and the outside unit was buzzing with the sound of the compressor. Its been working fine overnight. My question is, should I just change the capacitor anyway or could it be an issue with the compressor itself? how do I figure that out? thanks!
I suggest you inspect all wiring.

I did your method of pushing in the contactor and it runs while pressed but when I let go it cuts off, I did it twice and the first time the contactor stayed pressed but after a minute it shut off but now it wont stay pressed Could motor be the cause, he says the fan could be over heating.
Sounds like a low voltage power supply problem to the outside unit, faulty thermostat, or faulty contactor.
@@electronicsNmore thanks for the reply, so I last night the ac worked all night but when I turned it on during the day it shut down completely again. I think I jumped the thermostat and still nothing. Thermostat has g,y,w,rh,rc, how would you jump that? I'm get cold air when I press the contactor in still. Fan in the attic is running still so I believe the board is good. Thinking I'll replace the contactor next, which letter do you jump to the rc screw?
Thank you for sharing so valuable information.

Question:
I have a 1.5ton 220 volts split unit AC. After few seconds of turning it on, the clamp meter reads 22 A then rise to reach 37 A for few seconds then it stops and the clamp meter reads zero or 0.1 A. What could be the problem ?
If the pressure gauges look OK, then the compressor is at fault.
