Whirlpool Error Code F3E3
Inlet thermistor
Common Causes
- 1Thermistor failure
A failed inlet thermistor can remove the high-temperature safety limit. If the dryer exterior becomes too hot to touch, disconnect power immediately.
Step-by-Step Troubleshooting
- 1
Locate the inlet thermistor — mounted on the heater housing or air intake plenum
- 2
Disconnect and measure resistance: approximately 50,000 ohms at room temperature for NTC type
- 3
Compare the inlet thermistor reading with the exhaust thermistor — they should be similar at room temp
- 4
Check for heat damage to the wiring near the heater element assembly
- 5
Replace the thermistor if readings are out of specification
Pro Diagnostic Tip
The inlet thermistor monitors incoming air temperature to the drum. On Whirlpool and Maytag dryers, if both F3E1 and F3E3 appear together, suspect a restricted vent system causing overall overheating rather than individual sensor failures. Always inspect the full vent path from the dryer to the exterior wall cap.
