There may be a problem with the cavity temperature thermistor or the associated wiring. Maytag recommends a one-minute power reset first.
Model compatibility: Maytag reuses codes across series and model years, so F3C may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
What this code means
F3C
There may be a problem with the cavity temperature thermistor or the associated wiring.
The code on screen
Your microwave displays F3C when there may be a problem with the cavity temperature thermistor or the associated wiring, as the Maytag text puts it. Maytag documents it for over-the-range microwaves.
The manual’s reset
Maytag’s reset starts by powering the unit down at the breaker(s), for one (1) minute. Power up again by turning on the circuit breaker(s). Monitor the display for one (1) minute and note whether the error remains absent. Finally, verify microwave operation.
If the display still reads F3C, assistance from a qualified technician may be needed.
Codes easily mixed up with F3C
- F3H: humidity thermistor
- F3H1: humidity sensor
- F3T1: user interface thermistor
- F2Q1: user interface (touchpad) or wiring
