I preheat the oven and after about 10 minutes I received an error code F3 E2. I then checked the resistance of my temperature sensor. It was 1101 ohms at room temperature, ~75 degrees. I read it should be about 1080 ohms. Is the reason for the error? Is the resistance tolerance that tight? I have a Whirlpool RBS305PDQ16 oven.

Thanks

Hi,

F3 E2 Oven temp too high - over 575°F (301°C) in COOK mode

1.Check sensor connection.
2.Measure sensor resistance (1080Ω at 70°F [21°C]. Add 2Ω per degree F).

3.If resistance is not valid, replace sensor.
4.If sensor resistance and connections are good, then check for
welded-closed relays on the control.

Check the wiring to and from the sensor also!

So how tight is the tolerance on the sensor? At ~75 degrees it should be 1090 ohms while my sensor recorded 1101 ohms. Is this enough to warrant replacement of the sensor? Or should I try replacing the control board?

I would say that is close enough....but sensors can also go funky once heated....given the 2 choices I'd go with the least expensive part first.

JMO.
