KitchenAid Microwave F3T4 Error Code

The F3T4 entry

KitchenAid lists F3T4, on the over-the-range microwave page, against the magnetron temperature thermistor and its wiring.

Background on the magnetron

The magnetron generates the microwave energy, though the article does not explain it. The thermistor in this code senses temperature for the magnetron. What happens when its reading is wrong is not stated by KitchenAid, so it is not stated here.

Reset procedure

1. Flip the microwave’s breaker(s) to off and leave them for one minute.
2. Flip them back on.
3. Watch for a minute to check whether F3T4 appears.
4. Verify that the microwave operates.

Only the breaker panel is involved; no cover has to come off.

When F3T4 is back

The article has no second owner step and gives service as the route. Leave magnetron work to a technician either way; that line is our general safety wording.

Other temperature codes

• F3T3 for the hood temperature thermistor
• F3T2 for the convection thermistor
• E24 for the overheat condition at 500F (260C)

Quote the whole code

F3T4 belongs to a numbered series, so give all four characters instead of “an F3 code.” Should the vent door or exhaust also seem off, say so, because KitchenAid lists those under other entries. Cooking performance, heat output and noise are not covered by the article, so do not read them into the code.
