What F3T2 means
F3T2 means there may be a problem with the convection thermistor or its associated wiring. Convection cooking relies on that thermistor to hold the temperature of the circulating air, so convection modes are the ones to expect trouble from; reset once, avoid convection until the code is cleared, and have the thermistor and its wiring tested if F3T2 returns.

What the oven does alongside F3T2
- Convection preheat that never completes — The control has no trusted temperature to reach.
- Convection or combination modes stopping with F3T2 — The control halts the mode it cannot regulate.
- Food browning unevenly before the code appeared — A thermistor drifting before it failed outright.
- Other functions still available — The fault is specific to the convection circuit on many models.
What triggers F3T2, most likely first
- The convection thermistor — First: the documentation names it, and it sits in the hot circulating air of every convection cook.
- The connector at the thermistor — Second: heat cycling loosens and browns terminals close to the convection heater.
- The wiring between thermistor and control — Third: insulation aged by heat inside the cabinet, or a lead disturbed in earlier work.
- A one-off misread — Last: a code that clears with a reset and stays away.
Check order for F3T2, and why
- Reset with the power off — A free check for a passing fault.
- Try a short convection preheat — Confirms whether the convection circuit is the one affected.
- Note how long before F3T2 appears — At once points to an open circuit; after heating up points to a connection that opens when hot.
- Have the thermistor and wiring tested — A technician measures the thermistor against the tech sheet chart with the unit opened safely.
Reset and owner-safe checks
- Reset the unit — Unplug it or switch off its breaker for a minute, then restore power.
Tools: breaker panel accessAbout 3 min
- Clean the cavity and fan cover, power off — Wipe grease and spatter from the cavity and the convection fan cover with mild detergent, keeping liquid out of openings.
Tools: soft cloth, mild detergentAbout 10 min
- Run a short convection preheat — Use the convection setting as the manual describes, empty only if the manual allows that for convection, and note whether F3T2 returns.
Tools: owner's manualAbout 15 min
- Record the pattern — Note the mode, the set temperature and how long the unit had run when the code appeared.
Tools: pen and paperAbout 2 min
Before any panel comes off
Safety
Unplug the unit or switch off its breaker before cleaning or removing anything; a capacitor can hold a charge after the power is off. If the unit can microwave, never remove its outer cabinet, because the high-voltage capacitor inside can hold a lethal charge after unplugging, and never run microwave power with the cavity empty. Convection surfaces stay hot after use, so let the unit cool before cleaning it.
When F3T2 needs a technician
Call if F3T2 returns after a reset, if convection preheat never completes, or if browning has been uneven for a while. The thermistor is reached by opening the unit, and the technician tests it and its connector before replacing anything, since connectors close to a heater can suffer heat damage.

Which models this reading covers
This reading of F3T2 applies to Amana units whose control reports the convection thermistor or its wiring with this code, as the table states. Which modes stop and where the thermistor sits depend on the model, and a model-specific page, where one exists, is the better guide. None is listed for F3T2 yet; the Amana oven code index below is the place to start.
