KitchenAid Over-the-Range Microwave Code F3T2: convection thermistor

What F3T2 means

KitchenAid over-the-range microwave hood combinations such as the KMHS120ESS and KMLS311HSS display F3T2 when there may be a problem with the convection thermistor, or its wiring. The thermistor tells the control how hot the convection area is. If that reading fails, the oven may stop convection or all cooking and show F3T2.

Common causes of F3T2

Convection thermistor failed
Wiring to the thermistor loose
Control misreading the thermistor

✓ One safe check you can try

1. Cancel and let the oven cool with the door open. 2. Clear any food residue from the cavity. 3. Leave the unit unplugged for a minute, then reconnect. 4. Try a plain microwave cycle with water. 5. If F3T2 stays, call us.

! Why to stop there

The part is in a hot area of the cabinet
A reading test points to the true cause
You approve the price in writing, and the work carries a 30-day warranty

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F3T2F3T2 questions

Does my microwave have convection?

Only some KitchenAid hood models do. The code is tied to that feature, so check your model and tell us when you call.

Can I still microwave?

Usually, since microwave heating is separate. Try it with a cup of water.

What if I never use convection?

The control still watches the thermistor and may display the code, so the problem needs repair anyway.
