Question about Goodman CLQ36AR49 Air Conditioner

2 Answers

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?

The air handler (which is on a separate breaker) runs, but the heat pump does not. Something is causing the breaker to trip. As far as I know things were working fine when the heater was running. I am going to try the heater again to see if the heat pump breaker trips.

Could be bad compressor could be shorted causing breaker to trip. or could just be a capacitor or even a fan motor. try changing capacitor do you know how to use volt ohm meter and amp meter if so i can offer more help

    Thanks for your response. I do know how to use a volt-ohm-amp meter. I disconnected the fan from the capacitor, and the breaker still tripped. I disconnected the compressor, and the breaker still tripped. When the fan and compressor were disconnected from the capacitor the breaker didn't trip. There is some sort of relay on the controller board that supplies the voltage to the fan and compressor via the cap and a terminal block. The relay is functionally in two parts: LVDR and HVDR. I believe that stands for low-voltage and high-voltage driver(?) relay(?). I did replace the cap, but the results were the same. Thanks for your help.

    I forgot to add that the breaker trips when the heat is on as well.

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.

SOURCE: AC breaker trips after 10 minutes

Whats the amp breaker? Is this for the inside unit or the outside condenser? If the inside and gas heat you have a bad fan motor, If its an electric furnace , the same, but if its the outside unit, the fan could be going bad, locking up and the compressor still runs and pulls high ampsand tripps breaker or the compressor is just pulling too many amps due to plugged coils with dirt , grass or weeds blocking airflow.(koolbreezes74401@yahoo.com)

SOURCE: tripping breaker

There is a short circuit in the fan motor or compressor most likely. Disconnect the common wire to the compressor and try again. If the fan comes on and the breaker does not trip you have a bad compressor or a bad wire touching somewhere. Also,check the capacitor. Is it bulgded out or a burned wire? Could be a bad capacitor.

either bad motor ....or.... if you are lucky a bad run capacitor. you will need some sort of capacitor checker and multimeter to diagnose it further.

The air handler does not come on


Check to see if breaker to unit has tripped.If it has you may have a bad motor. You may have a bad control transformer in the air handler,not sending 24 volts to tstat.

My 5 ton Goodman Heat Pump won't go into heat or ac mode. Fan won't turn on. No noise from compressor. System is 1 1/2 yeras old.


Easy: Turn the "fan" switch to on at the thermostat and see if the blower starts. If no start, check breaker at breaker box. Check service disconnect at or near the air handler. With the breaker and/or service disconnect OFF check the 3 or 5 amp fuse inside the top cover in the air handler.
Not so easy: (You must know what you are doing for this part or let an HVAC Tech do it for you) Open thermostat and firmly jump the Y and R terminals to see if you get the compressor to start for no more than 30 seconds. (don't do it more than once.) Jump the G and R terminals to see if you get the blower to start. If so, u have a bad thermostat. If not, check the transformer inside the same cover in air handler for proper voltage. (24V. Make sure you also get 220 on the opposite side of the transformer)
If the blower comes on, but the heat pump doesnt start, open the side cover of the heat pump, with the thermostat on cool, and the temp. setting as low as possible for at least 10 minutes see if the contactor is pulled in. If so, check the capacitor and see if it's blown out. Be super careful these systems operate with 220v and the amperes are enough to kill you if you make a simple mistake.

Amana Heat Pump Tripping Breaker


My guess I would say, you either have a wire that is short to ground or if the contacter pulls in, then I would say the compresser is short to ground.There also could be some capacitors that could be short.

40 amp breaker at panel to air handler trips when you turn the heat on but not when the air is turned on


You could have one of two problems.

One , heaters could be shorted out causing the breaker to trip from and overdraw of current.

Two, your breaker could be weak and tripping prematurely.

Heat pump trips circuit breaker


I seem to have the same problem. But when I reset the breakers, they won't stay in the on position. They go back to the off position. What gives? It is 95F inside the house.
