Whirlpool Washer Error Code 322

Error code 322 means the compressor motor inverter board has reported a fault. The inverter board controls power delivery to the compressor motor, which is part of the drying system. The code appears when the board detects a problem it cannot continue operating through. Diagnosis starts with checking line voltage at connector CN8 on the inverter board.

A reset may temporarily clear the code, but it will return if the underlying fault is not repaired. If the inverter board is detecting a real problem with its power supply or the compressor motor, the fault will reappear during the next cycle. Always diagnose the root cause before relying on a reset.

Repair costs vary depending on the root cause. If the issue is simply a loose connection or a voltage supply problem, costs may be limited to a service call fee, typically in the range of $75 to $150. Replacing a compressor motor inverter board generally runs between $150 and $400 including parts and labor, while compressor motor replacement can cost significantly more.

Some causes of this fault, such as a loose connector at CN8 or a tripped circuit breaker causing low voltage, can be addressed without professional help. However, testing voltage at internal connectors like CN8 requires a multimeter and comfort working around live circuits. Replacing the inverter board or compressor motor is best handled by a qualified technician.

It is not recommended to continue using the washer while this fault is active. The compressor motor inverter board has detected a fault condition, and running the machine could cause further damage to the inverter board, the compressor motor, or related components. Address the fault before resuming normal use.
