Whirlpool Dryer F3 E1 — What It Means & How to Fix It
Also shown as F3E1 on some models.
F3 E1 relates to the dryer's exhaust thermistor, the sensor that reads outgoing air temperature — reset power for one minute and run a timed dry, and call a technician if it returns.
What this code means
Whirlpool labels F3 E1 "Exhaust Thermistor". The thermistor measures the temperature of air leaving the drum so the control can regulate heat. The article lists only the power reset and a timed dry test.
Whirlpool gives only the component name for this code.
