GE Washer Error Code 306

Error code 306 on a GE washer indicates a Compressor Motor Inverter Fault. The compressor motor inverter board has detected an internal fault condition and reported it to the main control board. This stops normal washer operation until the fault is diagnosed and resolved. The issue may involve supply voltage, the inverter board itself, or the compressor motor and its wiring.

No, you should not continue using the washer while code 306 is active. The fault indicates a problem with the compressor motor inverter board, and operating the machine in this condition could worsen the damage or create a safety hazard. Disconnect the washer from power until the fault is properly diagnosed and repaired.

A reset may temporarily clear the code, but if the underlying fault condition still exists, the code will return when the washer attempts to operate again. Resetting without diagnosing and correcting the cause is not a permanent solution. The inverter board fault must be resolved by addressing the supply voltage, wiring, or the defective component before the washer will operate reliably.

Some basic checks, such as verifying the electrical supply voltage and inspecting connector CN8 for loose or corroded connections, can be performed by a knowledgeable DIYer. However, working with 102 to 132 VAC components carries a shock hazard, and replacing an inverter board or diagnosing motor windings typically requires electrical testing experience and proper safety precautions. If you are not comfortable working with AC voltage, a qualified technician should handle the repair.

Repair costs depend on the root cause. If only a connector or wiring repair is needed, costs are typically lower, often in the range of $75 to $150 for a service call and labor. If the compressor motor inverter board needs replacement, parts and labor combined can range from $200 to $450 or more depending on the specific model and local labor rates. A compressor motor replacement would be at the higher end of that range.
