Understanding F3T1
Over-the-range Maytag microwaves show F3T1 when the user interface thermistor or its wiring may have a problem. Only that model family is covered by this code.
What to try
Switch off the breaker that powers the microwave.
After one minute, switch it on.
Look at the display for the next minute.
Check the microwave runs.
Still showing the code
If F3T1 comes back, arrange a technician visit so the thermistor and wiring can be examined.
Compare with
F3T2 is the convection thermistor, F3H1 is the humidity sensor and F2Q1 refers to the touchpad.
