GE Washer Error Code 311

Code 311 on a GE washer means the compressor motor inverter board has detected a fault condition. The inverter board controls the compressor motor and has flagged an error that is stopping the machine from running. The first step in diagnosing this code is checking the AC line voltage at connector CN8, pin 4 to pin 1, which should read between 102 and 132 VAC.

No, you should not continue running the washer while code 311 is active. The fault indicates the compressor motor inverter board has detected a problem, and operating the machine in this state could cause further damage to the inverter board or compressor motor. Stop use and diagnose the issue before running another cycle.

Repair costs for code 311 vary depending on the root cause. If the issue is only a loose connector or a wiring fix, costs may be limited to a service call fee, typically in the range of $75 to $150. If the compressor motor inverter board needs replacement, parts alone can range from $100 to $300 or more depending on the model, with total repair costs including labor often falling between $200 and $500.

Some causes of code 311 are DIY-friendly, such as confirming proper line voltage at the outlet or reseating a loose connector at CN8 on the inverter board. However, working near live AC voltage inside a washer carries a serious shock risk, so this work should only be done by someone comfortable with electrical diagnostics. If the inverter board itself has failed, replacing it typically requires disassembling the machine and handling high-voltage components, which is generally better suited for a qualified technician.

A power reset may temporarily clear code 311, but if the underlying cause has not been corrected, the fault will return as soon as the washer attempts to run the compressor again. Resetting is useful as a first step to rule out a one-time glitch, but a persistent code 311 requires proper diagnosis of the line voltage, wiring, and inverter board.
