F3T3 explained
Maytag ties F3T3 to the hood temperature thermistor and its wiring. It appears on microwaves mounted over the range.
Reset
Switch the breaker off and keep it off for a full minute. Turn it back on to power up the unit. Watch for a minute to see that no code returns, then verify that the microwave operates.
After the reset
If F3T3 is displayed again, the next step is a technician visit.
Codes in the same group
F3T4 covers the magnetron temperature thermistor, F3T2 the convection thermistor, and F3H1 the humidity sensor.
San Francisco service for Maytag microwaves
San Francisco and Bay Area households can book Maytag microwave repair by calling (415) 649-2156. It speeds things up to have F3T3, the model number and your reset result ready.
Model compatibility: Maytag reuses codes across series and model years, so F3T3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
