Maytag Dryer Error Code F3 E1
Exhaust thermistor open
Common Causes
- 1Exhaust thermistor failed
- 2Wiring to thermistor damaged
- 3Connector corroded
A shorted thermistor can allow overheating beyond safe limits. If clothes come out extremely hot or you smell burning, stop using the dryer immediately.
Step-by-Step Troubleshooting
- 1
Locate the exhaust thermistor mounted on the blower housing or exhaust duct inside the dryer
- 2
Disconnect leads and measure resistance: approximately 10,000 ohms at room temperature (72F)
- 3
Apply a heat gun briefly — resistance should decrease smoothly. No change means failed sensor
- 4
Check the wiring from thermistor to main control board for breaks or loose pins
- 5
Clean the exhaust duct and lint screen — restricted airflow causes thermistor overheating
Pro Diagnostic Tip
The AccuDry sensor system uses the exhaust thermistor to modulate heat. A failed thermistor causes the dryer to either overheat (if shorted) or run with no heat (if open). Always check the vent system first — a restricted vent cooks thermistors. Sacramento homes with long vent runs (>15 ft) see this frequently.
You Might Also Notice
