F3T1 refers to the user interface thermistor and its wiring.
Model compatibility: KitchenAid reuses codes across series and model years, so F3T1 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Possible problem with the user interface thermistor or its wiring.
F3T1 at a glance
KitchenAid’s over-the-range microwave page gives F3T1 a brief entry that names the user interface thermistor and its wiring as the suspects.
The F3T codes side by side
The F3T1 to F3T4 series each name a different thermistor, worded as follows on the support pages:
No symptom, cause or owner inspection is described. Only background can be added. Thermistors sense temperature, and the user interface is the control panel area, which is where this one belongs.
Breaker reset steps
Switch the breakers off for a minute.
Switch them on.
Watch the microwave for one more minute.
Make sure it operates normally.
If the code stays
The one suggestion left is to contact service or book an appointment. Should a different code show instead, F2E1 covers the keypad.
What the page does not settle
The source never says how long the code lasts, whether cooking stops, or whether the display and buttons are involved, so no such claim appears here.
Calling about F3T1
Quote the whole code, F3T1 rather than F3, name the microwave and mention the reset. Keep covers on; anything inside is technician territory.
