The circuit breaker could be tripping because its old and getting too warm; it could trip because of a short circuit or an overcurrent condition. You need an ammeter so that you can check the current draw on the line.

The ammeter will also assist you to find which component is drawing too much current, or if the problem is a short circuit.

Make sure the coils on the outside unit are clean. If not, hose them out, then reset the breaker and see what happens. If it trips the breaker again, then you've got deeper issues with the unit. Could be expensive (compressor), could be not so expensive (fan motor) or could be less expensive (contactor or wiring)
If you're lucky, the compressor over-amped due to dirty coils, but if cleaning doesn't do it for you, you're in for a service call.

Could this keep the air conditioner running and trip the breaker


Air conditioner may draw high current. It may trip the cirucuit breaker. You may check the current rating of the air conditioner. If it is higher than the circuit breaker rating, it surely will trip. If it is close but lower, it may trip as there may be other appliances connected.

Breaker keeps tripping on outside air conditioner unit


The compressor is probably drawing to many amps. Breaker could be weak also.. Need to check the amp draw on the compressor.

If the breaker is hot when it blows, the compressor is probably going bad.

Trips breaker and will not cool or heat


Disconnect compressor leads and tape them up. Restore power, if the breaker does not trip, than you have a grounded compressor.

If breaker trips again, hook compressor up and disconnect blower, if breaker does not trip you have a
bad blower motor.

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.

My Amana heat pump model PHD60C02F1 Keeps tripping the circuit breaker


Is this kicking the ground fault on the cord or the breaker. If it trips breaker could be bad breaker. If it trips quickly it is a short in the unit. Russ

AIR CONDTIONER TRIPS CURCUITS


Possible loose connections on the wires to the breakers,
or in the unit. loose connections casuse the wire to overamp and trip the breaker.
Also it's possible the breaker it's self is bad.
there ar also other possibilites but the 2 formentioned is the most common cause.
