I have a Kenmore model #40121. I tried to use it today and after it was on for about 15 minutes at 425 degrees it started beeping and flashing F3. I turned it off and back on and about a minute later it did it again. So I turned it off and let it sit for a few minutes. When I tried to turn it on again it kept defaulting and showing F2. Can Anyone help?

Good Afternoon Friend,

I see that your Frigidaire double oven heats up for about 15-30 minutes, then shuts down and begins beeping while showing an F3error code. The F3 states that the oven is sensing a potential runaway temperature. This is possibly a sensor issue or it could be a false error code.

I suggest giving your double oven a hard reset by cutting the power at the circuit breaker for at least 2-3 minutes.

After restoring power you will need to reset the clock. You will do this by entering in the time and pressing start.

Let the oven heat up, and if you are still receiving an F3 error code, I suggest either contacting the manufacturer or contacting your local authorized technician to diagnose your appliance. Hope this helps.

Hi!

For unlocking the Kenmore oven, please press and hold the STOP/CLEAR button for 3 seconds.

Please let me know if it helped


Best regards!

F3 usually means, that the oven temp. sensor is bad and one need to replace it.
The fact, that it's not heating tells me, the fuse in the back also needs to be replaced (requires pulling out).

HI. this is a basic temp sensor issue. the oven control is programmed to cease operations if it dose not receive any resistance signals for the temp sensor during high heat situations.

Check sensor harness and harness connection between oven sensor and oven control. Replace oven temperature sensor (RTD) if wiring is ok.

i think f3 error code has something to do with the temp probe maybe it is the problem. the temp probe is located if you open the door directly in the back wall. it looks like a prong. should read 1100ohms the f2 error code though usually has something to do with the keypad i would check all the connections maybe they are loose.
