Carrier a/c tripping circuit breaker

This is a fc4bnb054 carrier heat pump. It occasionally trips the breaker on the unit. I have used a meter and checked electrical connections and voltages and the only thing that I found was that I could not get a reading from the output side of the transformer. Could this be the problem or do I need to look somewhere else?

    I am sorry.. It is the breaker on the unit itself that feeds the transformer, heat strips, fan etc.. I pulled the heat strips out and they visually look ok with no breaks or burned spots on them.. thanks fotr the assistance.

    This is an older home and has been working in the past... It is a heat pump and the heat strips are not even in use when this is happening..Could a bad transformer be causing the problem as it is hooked up to the breaker? thanks again for the assistance.. ric

    Which breaker you should have one at the unit on the heat strips and one in the panel for the house?

I believe you are tripping the breaker because you are too close to the capacity of the breaker based upon the distance from the panel to the heat pump. If you are electrically skilled you could check this by measuring the distance and then looking at the standard to see. If this makes little sense to you, you may need to have an electrician check for u. Either way, good luck with it.

Carrier model 38tdb air conditioning unit kicks out the 40 amp breaker. Also moisture under compressor unit outside. What is problem?


What breaker? The breaker for the condenser? Likely have a compressor shorted to ground or drawing locked rotor amps. Easiest way to tell is make sure breaker off, unhook compressor wires from contactor. Turn on breaker and turn on machine. If the breaker does not trip, obviously problem with compressor

Any ideas as to why the panel breaker for my Goodman CPE24-1AB heat pump would immediately trip when the air conditioner is turned on?


Without looking up the specifications for this heat pump, I cannot be certain, but I expect the operation to provide cooling may require more power than when heating. You probably can find the specifications online for this unit. As you probably know, power is measured in watts and is calculated by voltage times current. This also is likely to be 240 volts operation. If you take the specified power on cooling and divide by voltage (240), that will indicate the current in amperage that will be required to start it. Your circuit breaker is set for current and needs to be a higher current than is required. If that is the problem, you can buy circuit breakers at Home Depot or Lowes. You have to remove the front panel of your breaker box and snap out the circuit breaker. To be safe it would be good to turn off the main breaker switch before you open the front panel and remove the circuit breaker for the heat pump. Should your calculation of current required be less than the rating of the circuit breaker, that implies a malfunction of the heat pump in the cooling mode and would require a service call to the local representative of the heat pump manufacturer.

You probably just blew the fuses or tripped the circuit breakers. There may be fuse right beside the unit in a box with a door on it. The fuses will be in a cartridge inside the box. You will need to change them both unless you have a ohm meter to check them. Also check your circuit breakers. The will more than likely be in your main circuit box. It will be two joined together, probably 20a or 30a. Trip them all the way back and then forward and try the unit again.

My unit is tripping the main breaker what should i look at first


With this cold weather, -- it is not likely tripping off because it is too hot!

Are you familiar with the history of this unit?-- Like has it tripped in the past during HOT weather?
This might be a clue, that the circuit is really loaded close to its limit--

This leads to the next possibility: That the breaker is getting weak (They do after many hard starting loads!
Now-- If you can get the system to start and run for just a few seconds-- can you put a Clamp around Amp meter on the wires?-- and read the full load current?
How close is this to the rating of the circuit breaker?
Is the breaker, and the wire size marginal?

Another thing to look for, is loose lug screws at the main fuses, and the Main contactors, and the motor leads--- for loose wires result in overheating, which raises the current, and leads to tripping, too.

How long ago was the condenser cleaned-- this leads to high amp draw too.

But the first thing would be to learn more about the age of the Main Breaker, and what the 'normal' run current is for that system.

Check with your contractor to see if their repair is warrantied. If it is not call someone who carries a warranty and satisfaction guarantee on repairs. It is likely that you got a bad capacitor, however, this typically will not trip a breaker. It's possible that other issue(s) caused the capacitor failure.
How old is this unit?

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

Breaker trips on roof top RV A/C


check your breaker is it hot to the touch?
check the wire tightness at the breaker?
remove the circuit breaker and inspect the terminals on the breaker and in the panel and the breaker itself for signs of overheating and discoloration due to the fact
check the connections at the unit itself
check that you have proper voltage to your unit
find the nameplate and look for FLA full load amp draw
is the breaker properly sized for the unit and is the wire size correct for the breaker?
(Check nameplate on unit)
buy a clamp on amp meter and see if it is under or over the nameplate rating when unit is running
take great care when you venture into electric,if you arent comfortable find someone who is.
you may have a weak breaker if all the above pass?
Replace it

Central air conditioner will not turn on at all.


I understand this to be a heat pump. Check your thermostat settings, and the filters. And make sure a breaker isn't tripped.
