    What is the model number of your Carrier? I.e Thru the wall / window unit, Split package type or central air? It does make some difference in the troubleshooting procedures.

Hi, if this unit is tripping the breaker when it tries to start, you have a part such as the compressor or a fan motor that is shorted. I would say it is the compressor as it draws more amp's then the other parts and if it has a locked rotor, it can draw as much as 55 to 70 amps depending on the size of the compressor. If you are inclined to check this out your self, it is a process of elimination. You will need to leave the breaker tripped off and disconnect the 3- leads from the compressor and tape the ends up. Now, hit the breaker. If it holds, you will know that the compressor is the faulty part. I bet this is as far as you will need to go. Depending on the condition and age of the unit, you will need to get estimates for a compressor change out or a new condenser. If the compressor is disconnected and the breaker still trips, go to each motor, the blower, and condenser motor and do one at a time to see which one is faulty if the breaker holds when disconnecting.
Please write down how the wires go back and don't forget to rate me on this as I know you will be kind. I will check in on you and keep all of your problems on file to go back to if need be. Keep me posted on what you find.

Dryer trips breaker after only a few mins of operation


Check to power at outlet for 220 volts

Check the breaker for the correct amperage cut off.

If the unit had an obstruction in the air flow, it would not trip the breaker.

Try running the unit with just cool air and see if it trips the breaker.

Odds are, you have a defective breaker.
Also, if the home is newly built, check the panel for loose connections at the breaker.
Or you could try a different power outlet, like the hot water heater.

If the unit continues to trip breakers on other outlets, you may have a short in unit.

Breaker trips on unit. Fuse in house is ok. As soon as AC unit turns on it trips the breaker outside next to unit.


you have a 'direct short' - most likely the compressor or fan motor.
you could isolate it to one or the other by (be sure all power is off) disconnecting one of them and turning the unit back on.
For example if the fan motor is shorted and you disconnect it - the breaker will hold and not trip and the compressor will come on - which will tell you that you need to replace the fan motor.
If you do this and it still trips the breaker then reconnect the fan motor and disconnect the compressor and try that.
If the breaker holds and the fan motor runs then you know the compressor is shorted.
Note: the fan motor can be replaced with not a lot of trouble depending on how mechanically inclined you are - but the compressor will take a qualified serviceperson.

Heat pump breaker tripped now no power to the unit at all


When AC unit trips the breaker it usually means one of four possiblities.

1) the AC unit is causing the breaker to trip, i.e. a shorted fan motor, compressor, or some other electrical component - in which case you will probably need to have a repairman look at it.

2) you've plugged the unit into a outlet that is connected to a breaker which is too small to handle the load the AC unit is putting on it.

3) a defective breaker (not likely but possible)

4) just a 'random' trip and if you reset the breaker it might work fine.

good luck!

Unit comes on and runs for 5 minutes, the circuit trips off


30 is the correct size breaker for this unit. It sounds like there is a grounding issue going on in the system. Or off of the Thermostat. Something is grounding out causing the switch to trip. Are you running #10 wire to breaker and the unit? If not you will need to increase your wire size

Not working


If the circuit breaker tripped,then the unit is trying to work and the remote is certainly telling the unit operate, otherwise it could never trip the breaker if it did not receive a signal from the remote. Your problem may be with the outside unit that te compressor is stalled (having a hard time starting ) and this will cause the breaker to trip. You need a porfessional to diagnose if it is the starter control, or relay, or capacitor, or bad compressor, or bad terminals.

A/C unit turned off- didnt realize we had a mat covering the unit


Hello,
If the breaker had tripped, you'd detect some looseness in the trip switch, even though it may not appear to be tripped. Once you have identified the correct breaker, trip it to OFF and then back to ON. Also check at the unit; it will either have a service disconnect, a fused disconnect or a circuit breaker at the wall. Compressor units have a thermal relay that causes them to shut down on high temperature. Let the unit cool down thoroughly. If this is the issue, and you are standing close enough, you may hear it reset when it cools. Usually, cool down occurs in 30 minutes or less. Try it again, but don't leave it unattended until it has made it through several cycles and you are confident that the unit is back to nornal. If any further issues develop from this incident, shut the unit down, trip the circuit breaker for the unit to off and call a serviceperson.
I hope this gets you going again!

Best regards, W/D

Tripping BreakerS


Same problem as both above. Humidifier trips after maybe 5 minutes. Top of machine is very warm; there's no on/off switch, so plugging in does nothing until the heat dissapates. What's the solution, to just buy a new piece of equipment?
