F3 E1Maytag Dryer — Maytag Dryer F3 E1 Error Code
Exhaust thermistor open circuit fault (combined fault code format)
F3 E1 is the combined fault code format used on newer Maytag dryer models and carries the same meaning as the standalone E1 code on older models — the exhaust thermistor has failed open circuit. The F3 prefix indicates the fault category (inlet/exhaust temperature circuit), while E1 specifies the failure type (open circuit). It is caused by the same conditions as E1: a failed thermistor element, a broken wire in the harness, or a corroded connector on the blower housing sensor.
Disconnect power and test the thermistor (WP8577274) on the blower housing with a multimeter. An open reading confirms the fault. Also inspect the harness connector for bent or corroded pins before ordering the part — a simple connector reseat resolves some F3 E1 codes without any part replacement. Replace the thermistor if it tests open; the repair takes about 15 minutes with a screwdriver.
