GE Dryer Error Code E3 — Inlet Thermistor Shorted
What this means
The E3 error code on GE dryers indicates that the inlet thermistor — the sensor that measures the temperature of heated air entering the drum — has developed a short circuit. The control board receives an abnormally low resistance reading and cannot regulate heat properly. This is most commonly caused by a failed thermistor, damaged wiring, or a loose connector at the thermistor plug.
Step-by-step fix
5 stepsReset the dryer
Unplug the dryer from the wall outlet and wait 30 seconds. Plug it back in and start a cycle to see if the error clears. A temporary electrical glitch can sometimes produce a false E3 code.
If the code returns immediately after a reset, the thermistor or its wiring is almost certainly the problem.
Locate the inlet thermistor
Unplug the dryer. Remove the top panel and front panel to access the interior. The inlet thermistor is mounted on the side of the inlet air duct inside the dryer, near where heated air enters the drum.
Take a photo of the wire connections before disconnecting anything so you can reassemble correctly.
Test the thermistor with a multimeter
Disconnect the thermistor wire harness. Set your multimeter to resistance (ohms). At room temperature, a working GE dryer thermistor should read approximately 10,000 ohms (10K). A reading of 0 ohms or very low resistance confirms a short circuit.
The resistance should decrease as the sensor warms up. If it reads near zero at room temperature, it is shorted and needs replacement.
Inspect the wiring harness
Before replacing the thermistor, check the wires leading to it for damage, pinching, or bare spots that could cause a short. Also check the connector plug for corrosion or bent pins. Replace the harness if damaged.
A wire pinched against a metal edge can intermittently short, causing the E3 code to come and go.
Replace the inlet thermistor
If the thermistor reads shorted, remove the mounting clip, disconnect the old sensor, and install the new one. Reconnect the wire harness, reassemble the dryer, and run a test cycle to confirm the error is cleared.
Make sure the new thermistor is seated firmly in its mount. A loose sensor can give inaccurate readings.
When to call a professional
If the thermistor and wiring both test good but the E3 code persists, the main control board may have a faulty input circuit. Board-level diagnosis should be handled by a qualified technician.
