GE Dryer Error Code E2

The E2 code on a GE dryer means the outlet thermistor has registered a short circuit condition. Specifically, the voltage signal from the thermistor dropped to 0.2 volts or below and stayed there for 5 continuous minutes. The dryer shuts down to prevent operation without reliable temperature feedback. The fault points to either a failed thermistor, damaged wiring, or a faulty connector in the sensor circuit.

Start by unplugging the dryer and locating the outlet thermistor, which is positioned at the exhaust outlet. Disconnect the thermistor and use a multimeter to measure its resistance. If the reading is near zero or shows a dead short, the thermistor should be replaced. If the thermistor reads normally, inspect the wiring harness and connectors for damage, corrosion, or loose connections and repair or replace as needed.

If only the outlet thermistor needs to be replaced, parts typically cost between $10 and $40 depending on the specific model, and the repair is relatively straightforward for someone comfortable working with appliances. If a professional technician is needed, total repair costs including labor generally range from $75 to $200. Costs can be higher if the control board or a larger section of wiring harness is involved.

Resetting the dryer by unplugging it or cutting power may temporarily clear the displayed code, but the E2 fault will return as soon as the control board detects the same low-voltage condition from the thermistor circuit. A reset does not address the underlying short. The wiring, connectors, and thermistor resistance should be tested and any defective components replaced before expecting the code to clear permanently.

It is not recommended to continue operating the dryer with an active E2 fault. The outlet thermistor provides the control board with critical temperature data used to manage heat levels safely. With a shorted thermistor circuit, the dryer cannot accurately monitor exhaust temperatures, which could lead to overheating or a fire hazard. The dryer should remain unplugged until the fault is diagnosed and repaired.
