Luxaire Air conditioner circuit breaker keeps tripping
If your Luxaire air conditioner trips the breaker, do not keep resetting it and hoping it holds. A tripping breaker usually means the unit is detecting a short or an overloaded electrical component. On many window units, the most likely issue is the LCDI power cord or cord-mounted circuit protector, which can trip before the main breaker if the cord or an internal component is shorted. If the power cord checks out, look next at the condenser fan motor, dual shaft fan motor, or blower motor. Shorted motor windings often trip the breaker as soon as power is applied and may leave a burnt smell. Less commonly, a damaged wire harness can short against the cabinet or another component, and a shorted control board may show burn marks or smell scorched. Whether you are dealing with a Luxaire air conditioner power cord problem, a window air conditioner that trips the circuit breaker, or an AC breaker that keeps tripping, enter your model number on RepairClinic.com to find the exact replacement part for your specific Luxaire air conditioner.
01 - Luxaire 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.

Common
02 - Luxaire 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 - Luxaire 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 - Luxaire 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 - Luxaire 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 - Luxaire 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.
