Check your wiring between the contactor and compressor for a short to ground, or check the compressor windings for short to ground.
With the Tstat off, the contactor should be open so the only way for the compressor to be trying to do anything is if the 110 volts from the unbroken side are traveling through the compressor to ground. Since 110v is not enough to run it, the overload is kicking it out, cooling off, and repeating the cycle. When you kick on the Tstat, the contactor is supplying voltage directly to ground without going through the resistence of the compressor windings and kicking the breaker.
Post back and let me know what you find.

SOURCE: my ac circuit breaker keep tripping

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.

Possible low voltage condition would cause that kind of a problem. To small a cord without the ability to carry and maintain the voltage would cause a voltage drop. I would test the voltage supply and make sure it is within 10% of that required for your A/C to operate properly.

Clicking sound is the contactor engaging to start the outside unit. Check for a burnt off wire at the contactor. For some reason you are not getting power to the outside unit. If you find a burnt off wire shut off all power to it then remake the connection at the point of the circuit break.

SOURCE: tripping circuit breaker

Replace the start/run capacitor and try it again. If that does not correct the problem you have a bad compressor.

Goodman CKl30 1d how can I tell if the outside box has tripped off?


look for red reset button.look where low voltage wiring comes in to unit.listen for buzz or hum from outdoor unit when thermostat is calling for heat.if heard,could be high voltage fuse or tripped breaker in panel next to unit.if not cautious electrocution can occur.suggest local service company for diagnosis.

USE EXTREME CAUTION WHEN EXAMINING high voltage wiring.









HIGH VOLTAGE SUPPLY. Open high voltage control box and turn off power by pulling dissconnect or switching off breaker.

Breaker tripping to a/c unit, unplug the fuse in the outside box to the unit and the breaker doesn't trip


You have a high voltage short (most likely) or the breaker is bad.
Turn power off to outside unit and remove service panel.
Look for any arcing or burned wires. Look down in the unit as well for these signs.
If you have eliminated the breaker as the problem and do not see any of the above signs, then the fan motor or the compressor is going to be the problem. More than likely the compressor. This will require replacing the compressor to repair the problem.
Hope this helps.

MY OUTDOOR A/C WENT OFF! BUT THE ONE INTHE INSIDE STILL WORKS ,BUT IT IS STILL HOT. WHAT IS THE PROMBLEM???


In most cases the outside unit is on a seperate breaker than the inside unit. Check your breaker box to see if any of the 220 volt breakers are tripped out. There may also be fuses or a breaker at the unit outside.

Where is the fuse box?


Does the indoor unit run?

It sounds like you're looking in the right place. Check your power panel for a tripped circuit breaker (maybe more than one) or if the home is older, it may have fuses. It's possible that the outdoor disconnect also has fuses but that's not as likely. You can check around the outdoor unit and see if you smell anything burnt.

You can aso turn off the unit at the thermostat, wait a few minutes and see if the unit starts back up, but check the items listed above first.

The a/c unit outside doesnt come on but the fan inside of the house is blowing, the unit is not cooling the house. I have a goodman unit.


Hi, this is a split system Goodman. With the j36 in the model number, that tells me it is a 3 1/2 ton unit. If the outdoor condensing unit is off and doing nothing at all, no fan on top running, no compressor or anything, it sounds as though you have lost power to it. The high voltage to the outdoor unit is seperate from the indoor unit. When it is not running, you have only warm air from the indoor unit. Before I have you do anything, go out to the unit. Take a water hose being careful not to bend the fins on the coil, and wash just the coil very good. If its dirty, it can cause the pressures in the system to rise very high and blow a fuse or trip a breaker. When you are done washing it, you should have a electrical box mounted on the wall that feeds power to this unit. First, find your main breaker box to your home. It should be where the meter is. Find it and it will have several different breakers in it. They may or may not be marked. Look for a double - pole 30 to 40 amp breaker that should say a/c, if it was marked. If not, look and touch them, it will be 2 breakers together and feel if they are tripped. If so, turn it off with a hard motion. Then, back on the same way. Watch to see if it holds and does not trip on you. If its ok, go to the outdoor unit. Make sure the thermostat is on auto/cool and turned way down for it to come on. If it was a breaker and its running, more then likely the dirt from coil caused it to over amp and trip. Now, if there is power and breaker is on but still not on, open the box at the unit. It may have a pull out type plug, or breakers. If it has a breaker, turn it off and on like the other. If it doesn't, behind a plastic panel you will have 2- fuses. Turn off power at main box breaker, and remove both fuses. They are cheap, so go get 2 at a hardware store and replace them. You can have them ohmed out to see if one was bad. After installing the new ones and you turn it on, and all is good, that was your problem. May sure you have power to this outside unit. If it was a blown fuse or tripped breaker and this continues to happen, you may have a internal compressor or condenser fan motor problem. Try the things I have said first. This may be the only problem you have. I do this for a living, 33 years and a licensed contractor. Please keep me posted and I will continue to help you if you need me. Let me know after you check everything.
Sincerely,
Shastalaker7 :)

The circuit breaker trips every time I turn the thermostat to on. The system hasn't been on in a few months, and when I turned it on today, it wasn't pushing cold air out. I saw that the circuit breaker...


You need to start with a basic inspection in the outside unit. For the breaker to trip immediately like that indicates a dead short. With the breaker OFF look at the internal wiring between the contactor relay and the compressor. You are looking for signs that the insulation may have been chewed by a rodent, or a wire is off of a terminal and in contact where it shouldn't be. If the wiring looks good, terminals pass tug test etc. you may have a shorted capacitor. Make sure to check the wiring for the fan too. You can disconnect the com lead for the compressor and fan one at a time to isolate the defective component if needed. Work safe! turn the breaker on for the test, and off again before you put your hand or tools back in.

I have outdoor Goodman compressing unit, model #cple24-1c. The breaker tripped and I was told to take out the connector located in the box by the unit and reset the breaker. The breaker did not trip again....


No, the electrical whip should be able to handle all weather, moisture, and even immersion. The only reason to replace a whip is if it has suffered some kind of physical damage. I recomend keeping an eye on it and if it trips again, have a pro come check out the system because something is not right inside the unit.
