Quick answer

What F3T2 means on a Whirlpool over-the-range microwave and how to try a power reset.

Model note: Whirlpool reuses codes across series and model years, so F3T2 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Whirlpool

What this code may mean.

A plain-language reading of the code — always confirm against your model’s documentation.

There may be a problem with the Convection Thermistor or the associated wiring.

F3T2 is the microwave’s way of pointing at the Convection Thermistor or the associated wiring. The guidance is for over-the-range microwaves.

Quick power reset

  1. Take power away with the breaker off, or the plug pulled, for one (1) minute.
  2. Power up the unit again by switching on the breaker.
  3. Let the microwave sit powered for one (1) minute and look for the code again.
  4. See that the microwave runs properly.

Once the reset has failed to clear F3T2, bring in a qualified technician.

Other codes to compare

  • F3T1 – another code about the user interface thermistor.
  • F3T3 deals with the hood temperature thermistor; easy to mix up with this one.
  • F4E9 is worth comparing, since it concerns the Smart Pop control.
