GE Dryer Error Code Inlet Thermistor

This error means the sensor that monitors incoming air temperature at the dryer's heating inlet is sending a reading outside the expected range. The inverter board cannot use the sensor for precise temperature control and falls back to the mechanical inlet thermostat to cycle the heater. The dryer will still operate, but with less accurate heat regulation. The fault typically points to a wiring issue, a failed thermistor, or a faulty inverter board.

The dryer is designed to continue running in a fallback mode when this fault is detected, using the inlet thermostat to control heat instead of the thermistor. This mode is less precise, so loads may come out over-dried or still damp. Running in this state for extended periods is not ideal and could cause unnecessary wear, so the fault should be diagnosed and corrected as soon as reasonably possible.

If only the wiring connection needs to be reseated or cleaned, there may be no parts cost at all. Replacing an inlet thermistor is typically an inexpensive repair, with parts generally ranging from $15 to $50 depending on the specific model. If the inverter board is the root cause, parts and labor costs will be higher, often ranging from $150 to $350 or more. Getting a diagnostic assessment before committing to a board replacement is strongly recommended.

Many cases can be resolved without professional help by checking and reseating the wiring connections between the thermistor and inverter board. If the connections look secure, testing the thermistor with a multimeter to check for an open circuit or a shorted reading is a practical next step. Replacing a thermistor is generally a straightforward repair that does not require advanced technical skills. If the board itself is at fault, replacement is more involved and may warrant a professional technician.

A reset may temporarily clear the error code, but if the underlying cause, such as a faulty sensor or damaged wiring, has not been addressed, the fault will return once the dryer runs again and the inverter board detects the out-of-range reading. Resetting is useful for confirming whether the fault is intermittent, but it is not a substitute for diagnosing and repairing the root cause.
