GE Washer Error Code 80

Error code 80 on a GE washer indicates a Humidity/Temperature Board Failure. The code appears when the control detects a communication failure with the humidity sensor board, or when the board sends humidity data outside the 0 to 100 percent RH range or temperature data outside the 0°F to 248°F range. Diagnosis starts with running service mode test 27 and inspecting the board wiring and connectors.

Error code 80 does not indicate a water leak or an electrical hazard, but the washer may not operate normally while this fault is active. The machine flags this code because it cannot verify humidity and temperature conditions during the cycle. It is best to have the fault diagnosed and resolved before running the washer through full cycles.

Repair costs depend on what component is at fault. If the fix is simply reseating a loose connector, there may be no parts cost beyond a service call fee, which typically runs in the range of $75 to $150. If the humidity/temperature board requires replacement, parts and labor combined can range from $150 to $350 depending on the specific model and local labor rates. A main control board replacement, if needed, would be at the higher end of that range.

A knowledgeable DIYer can check and reseat the wiring harness connectors leading to the humidity/temperature board, which sometimes resolves the fault if a connector has simply worked loose. However, accessing the humidity board and running service mode test 27 requires comfort working inside the washer cabinet. If the board itself has failed, replacing it is a moderate repair that involves disconnecting the harness and swapping the board.

A reset may temporarily clear the code, but if the underlying issue with the humidity/temperature board or its wiring is still present, the code will return during the next cycle. Clearing the fault without addressing the root cause does not fix the problem. A proper repair requires diagnosing whether the fault is in the wiring, connectors, or the board itself.
