Air conditioner model # 38ckc 42..350 not working, keeps tripping the breakers, had electrician check out and stated it was the fan or the compressor, i bought the house in 2009, was built in 2005, what do u think, should i replace the fan, its turning but blows breaker, and were do i get the part

call an electrician to do an insulation test and a short circuit test
either failure will trip a circuit breaker

tripping circuit breakers indicate shorts in the system or overload from a compressor failure
call in a technician to properly diagnose the problem and get a quote

Sounds like a short to ground problem with either the motor windings shorting to ground or a high voltage wire shorting.

Your condenser is either pulling too many amps and needs to be service by a tech or you have a weak breaker that needs replaced by an electrician.

When you say breaker box clicks and then warm air, are you referring to the actual breaker switch in your power panel, or clicking at your ceiling assembly? When the breaker trips, the air conditioner should shut down completely, is that what happens? The compressor kicking in and out could cause circuit breaker to trip. Did the electrician record incoming voltage supply, and what was it ? 115 volts?

Hi,

Here is a tip that I wrote that will help you ti find out why the circuitbreaker is tripping.

Circuit Breaker Keeps Tripping

High amp draw can be caused by a few different things, so first check that incoming voltage to trailer is sufficient. (115 volts) Not unusual for some parks to install more hydro hook-ups on a feed line, and when all are up and running, your incoming voltage could be decreased. If your o.k. that way, then I'd start looking at the compressor circuit of your ac, in particular, the compressor start-up capacitor. The capacitor basically stores electricity and boosts it to higher voltage for compressor and fan start-ups to reduce current draw that will trip the breaker. Please have a knowledgeable electrician, or RV tech check this for you, as a capacitor can give a real good high voltage (possible fatal) shock, even when power is off to unit. I also suspect that the start relay has shorted (welded) itself due to high amp draw situation, and that is reason it comes on by itself.

The first thing I would check is the outdoor unit coil and see if it is restricted(dirty). If that is the case then you can wash it off with water(make sure you shut the power off to the unit first). If the outdoor coil is restricted and has little air flow thru it ,it can't get rid of the heat from the space and the compressor will draw over amperage and trip the breaker.
The next thing to check is if the outdoor fan is running. If the fan doesn't run it is the same as the restricted coil, it can't get rid of the heat from the coil. Check these things first then we can go from there! Thanks!!

Sounds like u have a defective unit

possible breaker is bad. Have an electrician do an amp test on the compressor which will tell you if the compressor is bad. That is the only way to test the compressor. I would change the breaker first due to the age of the breaker and (if it hasn't been changed out before) due to the amount of time the breaker has ran your a/c system. I f this breaker continues to trip I would have the units compressor checked on amps being pulled from electric service
