Arcoaire Central air conditioner circuit breaker keeps tripping
An Arcoaire central air conditioner that keeps tripping the breaker may have a shorted condenser fan motor, the most likely cause. If the outdoor fan motor will not turn freely or its windings test short to ground, it should be replaced. The outdoor fan motor itself can cause the same problem. Next, check the furnace or air handler blower motor and blower wheel for seized bearings, a short, or a burnt smell. Less commonly, a shorted compressor in the outdoor condensing unit, a damaged control board, or a broken or loose wire harness can cause the central air tripping breaker, AC breaker won't reset, or air conditioner circuit breaker keeps tripping symptom. Do not repeatedly reset the breaker. Turn off power at the disconnect box and circuit breaker before inspecting visible wiring, and hire a qualified HVAC technician for 240V testing or repairs inside the electrical panel. Compressor work may also involve the sealed refrigerant system and requires EPA 608 certification. Enter your Arcoaire model number to find the exact condenser fan motor, blower motor, compressor, control board, or wire harness replacement part for your specific central air conditioner.
01 - Arcoaire Central Air Conditioner Condenser Fan Motor
If the outdoor condensing unit's breaker or fuses keep tripping the condenser fan motor may be to blame. To determine if the condenser fan motor is shorted, use a multimeter to test the motor windings for a short to ground. If the condenser fan motor will not turn freely or the windings are shorted, replace the condenser fan motor.

03 - Arcoaire Central Air Conditioner Blower Motor
Since the furnace or air handler's blower motor is the component that circulates the air through the home's venting, a defective blower motor may result in the circuit breaker tripping. You can try disconnecting the motor from the control board and see if the breaker still trips. You can also use a multimeter to test the blower motor for an electrical short, or see if there are any burnt smells coming from the motor. You can also try turning the blower wheel by hand. If the wheel does not turn freely, it's likely the motor bearings have seized. If the motor doesn't turn freely or is shorted the blower motor will need to b...

04 - Arcoaire Central Air Conditioner Compressor
The compressor is located in the outdoor condensing unit and gets power through a service panel box next to the unit. If the compressor is shorted the fuses in the service panel box or the main breaker box may trip. You can test the compressor for shorts by using a multimeter. If the compressor windings are shorted the compressor itself or the whole unit will need to be replaced.
Less Common
05 - Arcoaire Central Air Conditioner Control Board
The control board regulates the power supply to all of the components of the furnace or air handler. If the control board shorts out it can trip the circuit breaker. A shorted control board will usually have burn marks or smell burnt and will need to be replaced.
Less Common
06 - Arcoaire Central Air Conditioner Wire Harness
A wire harness sends power and low voltage signals between the electrical components and the control board. If a wire harness becomes damaged, it can short out causing the circuit breaker to trip. Check the appropriate wire harnesses for breaks or loose connections. A damaged wire harness will need to be replaced.
