GE Dryer Error Code Outlet Thermistor

The Outlet Thermistor error on a GE dryer indicates that the outlet thermistor is returning a reading outside of the expected temperature range. The outlet thermistor is a temperature-sensing component positioned at the air exhaust point of the dryer drum, and it communicates temperature data to the inverter board. When that signal falls outside the acceptable parameters, the control system flags the fault and automatically limits heater output to 60% of maximum power as a protective measure to prevent overheating or unsafe operating conditions.

The inverter board depends on accurate thermistor data to regulate the heating cycle efficiently. If the thermistor sends a reading that is too high, too low, or erratic, the board cannot trust the thermal feedback loop and compensates by reducing heat output. This limitation will result in longer drying times and potentially incomplete drying cycles. The root cause is most often found in the wiring path between the thermistor and the inverter board, where loose connectors, damaged wiring, or corrosion can introduce resistance or signal interruption.

Diagnosis should begin at the wiring connections between the outlet thermistor and the inverter board, as poor electrical contact is the most frequent trigger for this fault. If the connections are secure and undamaged, the thermistor itself should be tested for proper resistance values at a known temperature to determine if the sensor has failed. A failed thermistor or a fault on the inverter board input circuit are the next most likely culprits if wiring is ruled out.
