I have replaced the temp sensor/oven probe with no change in oven behavior.
I then replaced the control board/clock timer and while it seems a little better, I still see the following behavior:
Oven will preheat just fine to 350 and stay there just great
I put in a cookie sheet of cookies and temp stays at 350 for a few minutes... I look again in a few more minutes and it was up to 375-400 or so.
So I opened the door a bit to bring it back down to 350. Sometimes it stays there for a while.
* I am using one of those metal-coil oven thermometers
- The thermometer is close to the cookie sheet... do you think that's an issue in giving a false reading? I will try it higher up in oven away from cookie sheet
- Is there a way to clean out the venting system for this oven, or does that never have a problem? Could that contribute to problem?
- Any other suggestions of what could be wrong?? I'm getting nervous with Thanksgiving coming up!
