Whirlpool Dryer F3 E3 — What It Means & How to Fix It
Also shown as F3E3 on some models.
F3 E3 relates to the inlet thermistor, which reads the temperature of air entering the drum; cycle power for a minute, test with a timed dry, and call service if the code returns.
What this code means
Whirlpool labels F3 E3 "Inlet Thermistor". This sensor sits on the heated-air side of the dryer. Whirlpool lists the power reset and a timed dry cycle as the only steps.
Not every dryer has an inlet thermistor; Whirlpool gives only the component name.
