Amana Central air conditioner circuit breaker keeps tripping
An Amana central air conditioner keeps tripping the breaker or fuse, the outdoor condenser fan motor is the most likely cause. A seized motor, shorted winding, or motor that does not turn freely can cause the air conditioner circuit breaker to keep tripping. The next most likely cause is the furnace or air handler blower motor, especially if its bearings are seized, it smells burnt, or its windings are shorted. Less commonly, a shorted compressor, control board, or damaged wire harness can cause central air tripping breaker problems. Turn off power at the disconnect box and circuit breaker before inspecting components, and never repeatedly reset a tripped breaker. Testing motors, the compressor, control board, and wiring involves 240V line voltage and should be handled by a qualified HVAC technician unless you are trained and properly equipped. Compressor replacement or any repair that opens the sealed refrigerant system requires EPA 608 certification. If you identify a failed condenser fan motor, blower motor, control board, or wire harness, enter your model number to find the exact replacement part for your Amana central air conditioner.
01 - Amana 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.

02 - Amana Central Air Conditioner 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 outdoor fan motor is shorted, use a multimeter to test the motor windings for a short to ground. If the outdoor fan motor will not turn freely or the windings are shorted, it will need to be replaced.

03 - Amana 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...
Common
04 - Amana 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 - Amana 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 - Amana 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.
