[@fernandoescobar692]

Thank you, it may sound funny but I encountered this problem today and I didn't know what the problem was, I'm a technicians helper, the technician didn't troubleshoot the way you did he just said that the compressor was the problem, but didn't give me further explanation, so thank you now I know how to test the compressor and the possible problems, really appreciate it.

[@CarlosAyala-zv4fu]

Thank you for clear explanation. My ac tech came out and could not get his multimeter to work to check the compressor. He tested it just as you did. By disconnecting the harness. I was thinking he may be scamming me and over fixing the problem. You put that to rest. Thank you.

A second comment. My daughter's system was tripping her breaker. A major AC repair company in town told her she needed a complete new system. Reason he gave was very vague. Something about a leak in the system causing rust in the Freon lines????? I told my daughter get a second opinion. This co. had just installed that system about ten years ago. Someone she knew from the office she worked in came and looked the system over. Turned out, there was a Freon leak. He fixed the leak, recharged the system, charged her 700.00 just for the gas cost. The co. wanted 14.000.00 to replace the entire system. Needles to say, that air conditioning company will never see another job from me, my family, or any of my friends.

[@WordofAdviceTV]

Oh wow. Yeah, that is quite the difference in estimates! 700 to fix and recharge is a very good price. Usually it would go over 1000 easy. Glad to hear it all worked out so well! Thank you for sharing! Stay cool :)

Wonderful infomation from the video and comments! I now know that because my condenser froze up, that's why the breaker kept tripping. Thank you so much everyone for your help!

[@averyalexander2303]

Great video! It's also possible to have a wiring problem in the house that trips the breaker, that happened to me. When I installed my mini split last year I needed to install a dedicated circuit, so I ran 10 gauge Romex from the electrical panel to the disconnect box. The breaker tripped the second I turned it on. After realizing that it still tripped the breaker with the disconnect out, I realized that the new Romex I used was defective, one of the hots was shorted to ground and was tripping the breaker. No external damage to the cable. Weird. This could also happen if someone accidentally damages wiring in the walls or attic by stepping on it or hitting it with a screw or nail.

[@jimiclemente1]

hey man, thank you for doing such a great job and making complete sense ... my fau was working but things weren't cooling down... went out side compressor/fan not turning...reset breaker and compressor buzzing but no fan spin.....gave the fan a push...it spun but very solwly...so i shut off..... removed cover and discharged/removed capacitor (mounting strap was covering voltage/cap specs) my cap is 60 and 7.5 uf i could only find a 60 and 5 uf) local hvac parts houses would not sell to me without license... replaced capacitor, used tinfoil to shim the stap so it would be tight around cap..and everything is working great..... im going to order the right cap from you (60 and 7.5) and keep the 60 and 5 uf as spare... . first real hot week in socal desert so techs were swamped..90 degrees inside by noon..so you saved me on this one.. your a great teacher.... best wishes to you

[@PaulPhoenix2010]

One word of advice, if your condenser is tripping your breaker remember to ALWAYS restore power from the breaker. If you take out the pull out switch/disconnect, then reset the breaker and then put back the pull out switch you risk sparking and burning the contacts in the pull out switch if there is a short in the condenser. Then you may need to also change the disconnect box on top of fixing the condenser. I am used to cutting power/restoring power to the condenser using the pull out switch so I learned that lesson the hard way.

[@TheRealDegen100]

Man all the lessons that I’ve learned the hard way.

Same arcing and damage occurs to the circuit breaker when you close it on a shorted circuit. Best to locate and clear the fault using your meter, before you energize the circuit at all. Circuit breakers are designed to clear overloads and faults, not as a tool for locating them.

Hey thank you for this excellent video. My a/c has started tripping the breaker and I just had an HVAC tech come out.

[@Honeyman76]

What would have been cool was if you had demonstrated the amp draw before cleaning the coil vs the coil caked in dirt and fluff. I wasn't aware until watching your video that amp draw would increase with a dirty coil. I knew it effected the condensers ability to remove heat from the refrigerant, but not how it effects the electrical aspect. Thanks for sharing!

[@shoaibchaudhry964]

My AC breaker kept tripping. Found out the capacitor was bad... replaced it and working like a charm.

[@guidodan1]

Happened to me too. Breaker tripping was secondary to the bad capacitor. Unit would try to start, but with a bad capacitor, the load would surge and breaker would trip. Changing the capacitor fixed it up. Jay has other amazing videos that cover capacitor replacement in detail.

[@wrobelmike]

👍 Thanks, bro! AC tripped is breaker then my main, I thought it was toast for sure. Following your lead I checked for catastrophic failure first (seemed easiest) and I had a burnt out spade connector that worked loose and sparked itself into a grave - right on the compressor. I didn't know where to start but you saved me an emergency elec-chicken call.

[@angelalburquerque7457]

Thank you for this great video. When the air filter is plugged, the tripped breaker will be the one for the indoor unit since the indoor fan will draw higher amperage . You were showing the reasons for tripped breaker in the condensing unit. Am’I correct or wrong ?. I will appreciate your comment .

[@WordofAdviceTV]

Yes you are right. A very dirty furnace filter would trip the furnace breaker but if that breaker trips, then the outside unit wont work as well. I said it wrong in the video, I thank you for correcting me :) Although, the dirty filter itself would not trip a breaker as that would actually lower the amp draw, it might cause something else to trip it though. I probably should have left the furnace filter out of this lol

[@dannycalk8051]

They are two different breakers!!

[@carlmccoy662]

Loose connections will also trip the breaker. Check them all. Especially the low voltage from the air handler to the condenser, if that is loose the contactor will start and stop the compressor with no delay. The connectors on the run cap and contactor sometimes are too loose, even brand new units. If they pull off easily, they are too loose. Squeeze them(just a little) with pliers so they will grip the tabs on the contactor and run cap.

[@michaelcostello6991]

Great advice. Thanks

[@milotorres6894]

Ditto on that response Mike.

[@hareshpatel6052]

Good Advice. Add one more thing. Check the wire at the breaker if it is Aluminum. If it is Aluminum, it may have oxide layer causing contact resistance heating. You have to disconnect the wire and sand with emery cloth keeping the wire strands covered in no-ox lube. Uncovered aluminum oxidizes instantly. Reconnect the wire and make sure it is a tight connection.

[@bhampton1969]

How do you check the low voltage from the air handler? Is that wiring checked in the a/c unit or at the air handler?

[@carlmccoy662]

@@bhampton1969 Check the wires that are connected to your contactor in the condensing unit. Make sure they are making good connection and the contactor is opening and closing with out chatter.

[@grahamholmes9737]

Wow thank you soo much. I was so afraid to even touch my outside unit... But i am a handy car guy. Your video helped me to look and see that mice or chipmunks have chewed wires causing a short to the compressor.

[@bobmederos270]

I watched your video and it’s very educational and informative. I believe I have a short in the compressor. Whenever I turn on the unit a spark flies out of the compressor Junction box, tripping the breaker, I’ve replaced the wire twice which burned out, so my analysis concluded that the compressor wiring must be shorted out. My question, my unit is 18 years old ,good men, should I replace the compressor? Or should I replace the entire unit? Mind you, I’m in New Jersey and a complete new unit is roughly $2300. Don’t know how much a new compressor will run for with labor.

[@WordofAdviceTV]

Typically if a unit is over 15 years old, it is not worth replacing the compressor. And if it's an R22 system, you may not even be able to find a new compressor for it since that refrigerant is getting phased out. If you have a multi-meter, I have a video on how to check the compressor if you want to double check it. (I don't remember if I go over that in this video) kzbin.info/www/bejne/ZpKkm2OfprVsa6M

[@Howie875]

Missed a couple of things. One of the major causes of "hard starting" is a bad run capacitor. This will not allow the compressor to start and it will draw "locked rotor power "which can kick the breaker .Same with the fan motor. A permanent split capacitor fan motor with a bad capacitor will run slowly or not at all, increasing the head pressure and amp draw. Another thing is short cycling, which is not allowing the pressure to equalize by having the compressor off for at least 5 minutes. Real common in the mercury stat days before electronic stats became popular with their built in time delays .Another one is loose wiring at the AC breaker in the breaker panel. A loose wire creates heat, and a breaker will falsely interpret this as excess amperage and kick the breaker. I have never heard of a dirty filter kicking a breaker. Normally this will freeze up a unit with ice but will drop the amp draw . Could be possible under these conditions to flood liquid back to the compressor and slug it (trying to compress a liquid instead of a gas) but this will generally mechanically destroy the compressor and is rare. Also this unit that you are using as an example already has a start relay and a start capacitor installed by the factory. This does the same thing as a hard start and you cant have both of them hooked up at the same time.

[@gideonlord-adem]

Good job. We'll explained.

[@grizzlywon]

And start and Run Capacitors going bad is way more common than this!!! In my heat, they go bad about every 3 years!

[@alfredcasasola]

I could be wrong but I thought that having an under charge unit should not trip the breaker but trip the overload in the compressor since it's overheating due to high superheat. Great video by the way!

[@cryptkhakithetoddfather212]

Undercharge drops amps so yes you are correct

[@davidhawken4638]

Enjoyed the video, one thing to be careful of though. If you disconnect the wires from the condenser fan and allow the system to run (say your issue is the breaker trips after a few minutes rather than instantly like with most shorts) you will over heat the condenser coil and compressor. If you try this step I would only allow the system to run for a very short time that way.

[@lovetrump1088]

Great reminder for the..uh...well forget that! Good one as although you would HOPE everyone would realize they can only test without the fan running only quickly like you said, I am sure many have let it all run with no fan....."I don't need that running too do I, nah!" Someone should have thanked you by now!🤣🤣

[@JeremyColombo]

Thank you for this video. Had already replaced my capacitors and the contactor. Breaker has been tripping. Fan has also not always been running though I can hear the compressor humming. Added the rapid start and waiting to see if that helps. Hoping not to have to replace the fan, though it seems to run smooth. Maybe it is getting overheated. Going to clean the condenser coils also.

[@JeremyColombo]

I ended up changing the fan motor on the condenser and ruined the fan blades trying to remove. Had to get a new fan too along with the hub. Then I put the fan blades on upside down. Cooling well now and not as well when the blades were the wrong way. They should mark them somehow.

[@waltschannel7465]

I just got useful tips from this video. I wasn't working on a large unit, but rather a portable unit. The principle is the same. Turned out breaker (20A!) Was tripping due to compressor not being cooled adequately. I added a fan blowing on the out side of the housing, near the compressor That brought the total current under 10 amps, even after several hours continuous use. I have a feeling the thermal switch at the top of the compressor is not working.

Checked the air handler and that was running fine, went out side and noticed the fan wasn't spinning. Went into the garage checked the breaker box and saw the breaker was tripped. Went to reset it, I hear a buzz and the breaker trips, Tried it again and same thing. So shut off the breaker, pulled the main power patch out by the a/c unit. I removed the a/c access panel, noticed the capacitor was not mushroomed out, looked at the contactor switch, nothing looked or smelled burnt. Wiring looked ok with no bare wiring exposed. Don't know if it's a bad contactor, capacitor or compressor. The unit is 2013 4 ton Rheem. Have an a/c guy coming out tomorrow.

I don't know if I understand the question.. So the breaker is intermittently tripping? Runs for various lengths of time? If it's intermittent then those usually take some digging into to figure out.. Could be a bad run or start capacitor, could be a loose/burnt wire somewhere, a defective delay board, etc..

I suppose it's possible but I have never seen that happen before. The thermostat is on the 24v circuit and the circuit breaker is for the 240v circuit..

Thank you for your nice video. Here is my situation. Hope you give me a good advise The breaker was always tripping. I opened the AC unit and found the incoming grand line was disconnected. I reconnected it and turned on the braker. No tripping and I heard a roaring sound from compressor for 30 seconds and stopped since the braker was tripped. Then, I disconnected 3 wires to the compressor from contactor & capacitor, then turned on again. No tripping and no sound. Next, I turned on the thermostat. I saw the small spark from contactor and the braker was tripped. Finally, I tried to disconnect the cable on compressor side after removed the top fan but in vain , too tight. I scratched the top paint and connected to 3 wires one by one by volt meter as you did. All are not contacted. (may not be accurate) The compressor may be good. I don't understand 1.Why the compressor is started when braker is on although the thermostat is off. 2.Why the braker is tripped when the thermostat is on after disconnected the compressor. Do you think that the problem is the fan or capacitor?

Then when the temp rose, when it tried to kick on, the handler blew, and the condenser motor spun momentarily, but then tripped the breaker. For the next couple of days, I could get it to come on initially, but same problem. Today, it won't even give me a one-time cool. So ... I unplugged the wires to the compressor, called for cool, and the breaker did NOT trip. Does that 100 percent automatically mean that it's a bad compressor? I'm a bit surprised it failed the way it did. The capacitors aren't bulged or leaking, but I thought I read they can cause a breaker to trip. Can they? Please advise prior to me hiring an HVAC guy who I know will automatically tell me I need a new compresser, then reason that I should get a whole new system.

It does not happen very often but it is possible for a bad capacitor to trip a breaker. If you have a multi-meter, you could check the capacitor and the compressor to know for sure.. If you don't have a meter, then I think replacing the capacitor is worth a shot. Although unfortunately a bad compressor is more likely.

@@WordofAdviceTV Thanks. Please note I did test the compressor by testing for continuity at the leads. They all showed numbers other than "OL." So doesn't that mean it's good/not grounded out?

Good video... Can a capacitor cause intermittent breaker pops? You mentioned a hard start kit but not a capacitor? Thanks

[@WordofAdviceTV]

Some people say it can but as for me, I don't remember ever coming across a run capacitor that was causing the breaker to trip.. I would suspect other things before that.

@@WordofAdviceTV Thanks for your reply. In the past few months the beaker has popped a few times several weeks apart. In the last 2 days it has popped 3 times. 3 and a half year old unit. Filter and compressor coils are clean. I'm going to read breaker temp with my ir gun today and inspect inside wiring area of compressor unit to see if something reveals itself.

@Scott Norman Good luck! Those intermittent problems can be hard to catch. I would check voltages too. If you have a meter. It's possible that you are experiencing a "brown-out" in your area and that can be messing with the unit.

my contactor was buzzing loud like one of those EM door locks. was told something could get behind and block it. blew it out and never really fixed it but my heat was working so i let it go. eventually it started to trip the breaker. ordered a new contactor and installed it. everything was fine and i wired straight from the old contactor to the new as not to get anything ixed up. i was careful not to let anything touch. it ran for maybe 10 minutes and then all the same symptoms as the breaker tripping came back. it shut off, no power to the thermostat etc... but the breaker is not tripped. outdoors or indoors. but no power to the unit. i looked for a reset button and couldn't find one. all fuses seem to be fine. any idea what my problem is. i'm freezing and broke so getting someone to come look isn't an option at the moment

I have an AC at work at the breaker kept tripping assumed it was a compressor replaced a compressor and it still trips didn't trip right away after a day or two it started tripping right when it came on I know it's a compressor because I disconnected it and everything was fine running but when I connect the compressor the new compressor it trips why?
