Amana Air conditioner circuit breaker keeps tripping
If your Amana air conditioner trips the breaker, start with the power cord. Most window units use an LCDI circuit protector that can trip if the cord is damaged or if a short develops inside the unit, and it may shut off before the main breaker does. If the cord checks out, the next likely causes are a shorted condenser fan motor, dual shaft fan motor, or blower motor. A burned-out motor may smell hot or burnt, and you can check the windings with a multimeter. A damaged wire harness can also create a short, especially if you find broken insulation, loose connections, or overheated wiring. Less commonly, a shorted control board can cause an AC breaker to keep tripping, often with visible burn marks or a burnt odor. Whether you are dealing with an Amana window air conditioner that trips the circuit breaker or an air conditioner power cord problem, enter your model number on RepairClinic.com to find the exact replacement part for your specific Amana air conditioner.
01 - Amana Air Conditioner Power Cord
Most window air conditioners have an LCDI circuit protector that will detect a short in the cord or a component in the unit. If the circuit breaker on the cord is damaged or any of the components in the unit are shorted the circuit breaker will trip. The circuit breaker on the cord is usually more sensitive and will trip before the main breaker.

02 - Amana Air Conditioner Condenser Fan Motor
An air conditioner condenser fan motor is the component that spins both the condenser fan blade in the rear of the unit. If the fan motor is burned out or shorted it may trip the circuit breaker. You can use a multimeter to check if the motor windings are shorted. A shorted motor will usually have a burnt smell and will need to be replaced.
Common
03 - Amana Air Conditioner Dual Shaft Fan Motor
An air conditioner dual shaft fan motor is the component that spins both the condenser fan blade in the rear of the unit and the fan blade that forces the cooled air out the front vent. If the fan motor is burned out or shorted it may trip the circuit breaker. You can use a multimeter to check if the motor windings are shorted. A shorted motor will usually have a burnt smell and will need to be replaced.
Common
04 - Amana Air Conditioner Blower Motor
If the blower motor windings are shorted out the breaker will likely trip when power is applied to the motor. You can try disconnecting the motor from the unit to see if the breaker will still trip. You can use a multimeter to check if the motor windings are shorted. A shorted motor will usually have a burnt smell and will need to be replaced.
Common
05 - Amana 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.
Less Common
06 - Amana Air Conditioner Control Board
The control board regulates the power supply to all of the components of the air conditioner. 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.
