Whirlpool Dryer Error Code F3 E1 — Exhaust Thermistor Error
What this means
The F3 E1 error means the exhaust thermistor (temperature sensor that monitors outgoing air temperature) is faulty or disconnected. Without accurate temperature readings, the dryer can't regulate heat properly.
Step-by-step fix
3 stepsPower cycle the dryer
Unplug for 2 minutes. A temporary sensor glitch may clear with a reset.
If the error appeared only once, this is likely sufficient.
Check thermistor wiring
Access the exhaust thermistor (usually near the lint trap housing or blower). Verify the connector is firmly attached.
Always unplug the dryer before accessing internal components.
Test thermistor resistance
Disconnect the thermistor and test with a multimeter. At room temperature, it should read approximately 10,000 ohms (10kΩ).
If the reading is wildly off or shows OL (open), the thermistor needs replacement.
When to call a professional
If you don't have a multimeter, a technician can quickly diagnose and replace the thermistor.
