GE Washer Error Code 354

Error code 354 on a GE washer indicates a Compressor Discharge Thermistor Fault for the NTC 1 sensor. This sensor monitors the temperature of refrigerant exiting the compressor in the washer's heat pump system. The code appears when the thermistor's reading falls outside the acceptable range, which can be caused by a failed sensor, a wiring problem, or an actual temperature issue in the heat pump circuit. Running Service Mode test 15 is the recommended first step to evaluate live thermistor data.

A power reset may temporarily clear error code 354, but the code will return if the underlying fault is still present. If the thermistor or its wiring is genuinely faulty, the out-of-range signal will persist and re-trigger the error. A reset is useful for confirming whether the fault is intermittent, but it should not be treated as a fix. Proper diagnosis using Service Mode test 15 is necessary to resolve the condition permanently.

Repair costs for error code 354 depend on the root cause. If the fix involves reseating a loose connector, there may be no parts cost and only a service call fee, typically in the range of $75 to $150. Replacing the discharge thermistor sensor usually adds $20 to $80 in parts. If the control board requires replacement, total costs including labor can range from $250 to $450 or more. Refrigerant or compressor issues represent the most expensive scenario and can exceed $500 depending on the extent of the repair.

Some causes of error code 354 are DIY-accessible, such as inspecting and reseating the thermistor wiring connector or checking for obvious wiring damage. However, accurately diagnosing the fault requires running Service Mode test 15 to read live thermistor data, which requires familiarity with the washer's service mode. If the fault points to the thermistor sensor itself, replacing it is a moderate repair. If the heat pump refrigerant circuit or compressor is involved, a certified technician is needed.

It is not recommended to continue using the washer normally while error code 354 is active. The fault affects the heat pump system's compressor monitoring, and running the machine without accurate discharge temperature data could allow the compressor to operate outside safe thermal limits. The washer may restrict or disable heat pump operation as a protective measure. The fault should be diagnosed and resolved before returning the machine to regular use.
