    My AC will run perfectly for 15 to 20 minutes, then it trips the breaker. I can immediately reset the breaker and it will run fine for another 15 to 20 minutes and trip the breaker again. ALL DAY LONG.

If your outside condenser has a locked rotor or short circuit, than the unit WILL trip the breaker - as it should. On the other hand if a breaker is tripped a few times it will have less of a capacity that the rating, (this is designed in it). You will need to determine if the unit is locked (and broken) or the breaker has become too sensitive.

My AC is running properly in the daytime when the input voltage is normal, but in the nighttime if voltage goes low then the breaker goes off (using triple booster V-guard stablizer without the option of low-voltage and high-voltage cut technology (model VIEW- 400)). I think the voltage is running below 100 (not sure). Give me the solution is there any problem in AC/stabilizer/wiring/low-volt current?

Since voltage is dropping it is forced to draw more current to get the required power. And this causes overheating of the wire, which trips ur MCB. It's a safety measure since overheating may even cause fire. In my opinion the solution is increasing the thickness of ur wire from Mains to AC and go for higher current withstanding MCB

Coleman mach rv ac unit tripping breaker


If it trips the circuit breaker as soon as you turn the FAN on, suspect either a bad fan motor or a failed fan motor start capacitor. If you are able to turn the fan on but the circuit breaker trips as soon as the COMPRESSOR starts, it is possible that the compressor is seized.
If, on the other hand, the unit is tripping a GFCI (Ground Fault Circuit Interrupter) breaker or GFCI utility outlet, it is possible that neutral and hot are reversed at the outlet into which the trailer is plugged (happened to me this year at an RV park).

Reset button ac unit


Hello jerrydj1021 - Often when the breaker trips, it is a mainly because there is too much current running on one circuit. Is the unit plug into a GFI outlet? It is not recommended to use GFI outlets or too many appliances plugged into that one circuit. Try plugging the unit into another direct outlet and see if the breaker trips again. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if the unit's status has changed successfully. Thank you.

Amana RCE24C2A trips circuit breaker


tripping the circuit means the unit is has a ground, "means some peeled wire inside is touching its metal case"

Breaker trips on unit. Fuse in house is ok. As soon as AC unit turns on it trips the breaker outside next to unit.


you have a 'direct short' - most likely the compressor or fan motor.
you could isolate it to one or the other by (be sure all power is off) disconnecting one of them and turning the unit back on.
For example if the fan motor is shorted and you disconnect it - the breaker will hold and not trip and the compressor will come on - which will tell you that you need to replace the fan motor.
If you do this and it still trips the breaker then reconnect the fan motor and disconnect the compressor and try that.
If the breaker holds and the fan motor runs then you know the compressor is shorted.
Note: the fan motor can be replaced with not a lot of trouble depending on how mechanically inclined you are - but the compressor will take a qualified serviceperson.

My amana ac unit over heats the circuit breaker and trips it off after running for about 15 minutes. It will not blow the fuses on the outside disconnect next to the unit outside.


What you described 'shouldn't' be happening - "if" the outside fuses and the inside breaker are sized correctly for your air conditioner.

I would make sure that the fuses in your outside disconnect were the proper size (for your AC), and that the inside breaker was of suffienct size to handle the air conditioner, and whatever else might be on the circuit.

Note: You would never want the 'outside fuse size' to be bigger than the inside breaker.

For example: 50 amp fuses in the outside disconnect and a 40 amp inside breaker is a no-no.

Often, for whatever reasons - someone will put larger fuses in the outside disconnect than what is called for.

When this happens the inside breaker is the only safety on the AC.

The problem is - for whatever reason - your inside breaker should not be tripping off.

It's likely that the AC may be on a inside breaker "that also has other things i.e. dryer, electric range or Refrigerator," and therefore any of these components 'including' the air conditioner could be causing the inside breaker to 'trip.'

One way to check this would be to 'un-plug' whatever else you had on the inside breaker - and then run your air conditioner and see if the breaker trips. Let's say you have the refrigerator and the air conditioner on the same inside breaker. You suspect the refrigerator is causing the inside breaker to trip - so you unplug it - and then turn on the air conditioner. "Now" it does not trip the inside breaker and assuming you have the proper fuses in the outside disconnect - you could safely say the air conditioner is ok - but - the refrigerator might be on the blink.

It's also possible that you just have too much on the inside breaker and you need to plug the refrigerator in to another outlet.

Still, if it was me - I think I would really think 'hard' about calling a Service Tech out - and let him/her diagnose the problem.

Hope this helps.

Everytime my central air unit kicks on my circuit breaker trips. It didn't do this last year or even earlier this year


A circuit breaker 'tripping' everytime the AC unit kicks on 'most always' indicates a direct short (somewhere in the condensing unit), although it is possible that the breaker itself is bad - (but not likely).

Usually the cause of this 'short' will be - either the condenser motor in the condensing unit (outside unit) or the compressor - also in the condensing unit.

If you're mechanically inclined - and "very careful" around electricity - there is a fairly simple way to find out which component is causing the short.

Step 1 - Make sure the condensing unit (outside unit) is completely disconnected (electrically) , i.e. pull the fuses/turn off circuit breaker on outside unit and turn off thermostat.

Step 2 - disconnect the condenser motor (this is the outside fan motor). Note: when you disconnect the wires of the condenser motor "be sure" you mark/write their location, and wrap them in electric tape.

Step 3 - start the AC unit. If the breaker trips again you can pretty much rest assured it's the compressor that is shorted.

To prove it (without a doubt) - go to next step.

Step 4 - "be sure circuit breaker and thermostat is turned off" - and - 'reconnect' the condenser motor - and - then disconnect the compressor wires (mark wires and tape them).

Step 5 - Start AC.

If breaker doesn't trip - you know it's the compressor that is shorted.

If breaker 'does' trip again - then it's possible the breaker itself is bad (not likely) or there is a 'short' in the condensing unit's "wiring" somewhere (not likely).

My guess is that either the condenser motor or compressor is shorted.

Hope this helps.

Good Luck!

Possible overcharge or bad breaker. You need to check the amp draw for the unit. If you draw under full load amps and trips breaker breaker is bad.Rus

Is your condensing unit located in a well ventilated area and have an ample space, atleast a foot, from the rooftop flooring? Just make a check that free flowing outside air properly ventilates the condensing unit specially on high ambient temperatures. Hope this would solve your problem

Breaker keeps tripping


If the breaker itself is more than 15 years old, replace it. If it continues to switch off, check the amp draw of both the inside and outside unit.
