I'm stumped and would love any insight anyone can provide. The unit was built and installed in the fall of 1996. I've rolled through a series of error codes based upon which part was replaced.
- I've tested the oven temperature sensor with an ohmmeter and ranges were in tolerance according to the chart provided on this site. I tested a range of temperatures from room temperature through 400 degrees. I also used a secondary oven thermometer to validate the oven's temperature at each increment.
- An F7 error led me to the initial testing of the temperature sensor. I also ran the F1 Touch Pad/ERC Test which led me to replace the ERC.
- Replacing the ERC changed the error code to an F1. Since the ERC was already replaced, I proceeded to replace the Membrane Switch next. For the most part, everything is good; however, the F1 error code still appears sporadically when I turn the oven off after a heating cycle. Sporadically would be 1 in 3 times in the last 5 days. My wife is still worried it may turn off on her in the middle of baking and ruin her hard work.
Does anyone have any additional troubleshooting tips or ideas? Replacing the entire unit is not high on my priority list since I've just put $400 into it in the last month.
