i have a dual wall mounted GE oven with the top oven displaying a f2 code after using the self cleaning mode. so i used the bottom oven to cook with but now after cooking the lower oven displays the same f2. it was installed in a new house in 97. i'm at work and dont have access to the model number right now. oh by the way its beeping everytime it displays the f2 code. any help would be great.
It appears that some ovens with ERC (electronic range control) will most likely to have some problems after self-clean cycle. These ovens use mainly oven temperature sensors.
Some of the following information from some web-sites could give us some insight "why":
(1) The temperature of the oven is very high (about 850 deg F (450 deg C)) during the self-clean cycle.
(2) The operating temperature range for NTC thermistors is from -100°C to + 300°C.
(3) Metal RTD's (Resistance Thermometer Device) offer a wide temperature range from -260°C to +850°C. But Metal RTD's are more fragile than NTC thermistors.
If they use NTC thermistors as oven temperature sensors, the high temperture during self-clean cycle will easily damage the thermistor-type sensors.
If they use Metal RTD's (as most are), they could stand the high temperture. However, Metal RTD's are very fragile because they are constructed with fine wire to obtain about 1000 ohm at 70 deg F. The expansion and contraction due to large temperature change (from 70 to 850 deg F) could break (or short-circuit) the fine wire.
