Every air conditioner has a motor called a compressor. The compressor provides the cooling capacity for the air conditioner. If the compressor or its electrical controls are defective the compressor may try to start, fail, and create an electrical overload. If the unit does create an overload, every compressor circuit is also equipped with an overload safety switch. The safety switch is designed to protect the compressor from burning out. The safety switch will cut the power to the compressor for a certain length of time and then reset itself. When it resets it will allow the electricity to flow to the compressor once again. If the compressor then starts, the unit should function normally. If the compressor doesn't start when the overload resets, the overload will again cut the electricity to the compressor. This cycle will continue indefinitely. (Always allow three to five minutes before restarting the compressor.) If this situation is occurring, unplug the air conditioner and get help from a qualified repair technician. This problem is often fatal to the air conditioner because the cost of repair often exceeds the price of a new air conditioner.

Grunaire unit trips breaker immediately when we try to reset it.

very likely a defective compressor. while there are other things that could cause the tripping, 90% of time it will be the compressor. generally, it will not be cost effective to repair the system if it is.

When compressor kicks in the circuit breaker trips and shuts off juice to outlet; when run in "fan" mode the circuit breaker does not trip. Am I doing something wrong? It was running at this...

This appears to be a direct short internally to the compressor . you neede a ohm meter to test it .. not certain how old the unit is but if its a window unit and over 6 years old I would buy a new one. But it does no0t sound good. In the future when a unit trips the breaker and you reset it and it trips right away its best not to trip it again as it contaminate the inside of thye system and is very difficult to clean and expensive as well . those are my thoughts. It could be the outside fan but the way you decribe it tripping right away my money is on the compressor

Our Friedrich Floating Air system keeps throwing the breaker. Worked fine for 5 years, now can't get it to stay on.

Check compressor is taking correct amps, if high amps due to capacitor weak, replace it. And also check for any short circuit in wiring.That is also the reason for breaker tripping.
Remove power. Check compressor terminals after removing wiring, When your ohms read something between any terminal and grounding, it's understood that compressor grounded. Replace it.
If windings reading should be : SR should read the total of CS and CR (C=COMMON, S=STARTING,R=RUNNING). If the total is higher or lower, the compressor winding is weak. That time it takes higher amps and breaker get tripped.
Hope helpful?

I have a ckl36-1h. I have had it for 6 years. The compressor will not turn on. Any suggestions?

1. Check the breaker to see if it has been tripped.
2. Check fuses on the outside disconnect switch.
3. Check contactor switch inside electrical panel on outside unit to make sure it is getting a call for cooling, you will hear a humming sound if it is working.
4. Capacitor is bad. Check with a multi-meter that read micro farads. Remove wires from the Herm terminal and place leads on bare terminals. Mfds should read within 5mfds of what capacitor is rated.

Anything else would require trouble-shooting the compressor which can get extensive. Also if you have tripped a breaker or blew a fuse, the compressor could have shorted out. In case of a short, do not keep trying to replace fuses or resetting the breaker. Hope this points you in the right direction!

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.

Keeps blowing the breaker... only 6 months old

This compressor is small however like other brands in this size range draw 13 - 15 amps. Thats quite a bit of power. The compressor has a thermal breaker that will begin to trip if compressor is hot. I am assuming that the breaker that is tripping is the one on the compessor. I have seen many hitachi breakers fail. Easy to replace with generic 20 amp, cost about $10. Before you replace anything, check amp draw with meter, if within specs try to determine what is causing heat.
cycling too many times per hour (check manual for recommended)
low power due to weak circuit or extension cord
using generator for powering compressor (not recommended)
using low quality oil (use synthetic if hot climate)
air leaking from intank checkvalve back to pump
If no reason to overheat then replace breaker on compressor to 20 amp but watch for overheating. Good luck

Air conditioner trips circuit only in the evening?

first off, it's illegal to release freon into the atmosphere. the epa could charge you $32,500, so keep it under your hat. second, if it's getting too cold where the evaporator coils are icing up, it's too lille freon, not too much. as for the breaker tripping, your compressor might be wearing out. if it's pulling too much current, the motor is failing and the compressor needs replacing. and do not do it yourself unless you're certified by the epa to move freon and have the proper equipment to recollect the used freon.

Air conditionin gunit keeps tripping breaker. A/C is carrier 5 years old compressor?

Sounds like you have a grounded compresser with a direct short.To know for sure you can disconnect the compresser and then flip the breaker and see if it still trips.If it still does check the motor,but this is most likley the compresser sorry.Carrier does have a 5 yr warranty so hurry and call someone it could still be in warranty!

AC Kicking OFF Breaker

Sounds like you have a problem with your compressor. If the beaker trips the second the compressor tries to come on hen it is shorted. If it takes a couple of seconds, then your compressor is locked up.

Breaker keeps tripping

If the breaker itself is more than 15 years old, replace it. If it continues to switch off, check the amp draw of both the inside and outside unit.
