I have a GE JTP18 Trutemp. It seems to be taking

The limit switch in a Ge oven usually works or is blown. I would look at the oven sensor located at the back of the oven. It should read approximately 1k ohm at room temperature.

Yes, the program and thermostat calls for the fan to cool the electronics, without that you can loose the electronic boards. Normally the fans will shut off once temps drop to 200 degrees Fahrenheit. Enjoy your new home.

You will need to press the stop/cancel button, next press the self clean button, you do not have to set the time the cleaning cycle takes approx 3-1/2 to 4 hours and the cool down takes another 45 minutes to one hour, it will clean and cool down and you do not need to interrupt this cycle, it will let you know when it is complete.

You have a stuck keypad. You can try pushing every pad several times at random to try and clear it. If that does not work,you have to replace the keypad control.

Yes, soap and water is fine. You can use any mild soap. Just do not clean with oven cleaner.

Mine was doing the same thing all day today. All I know is when it was cool I lifted up a bit on the lower burner an inch or so, and set it down. Next thing ya know, you guessed, it, it's working again...Not sure what's doing it, will keep checking for a solution.

hey - I figured it out! hold down the 9 and 0 at the same time for 3 seconds! or it might be another combination depending on your oven - it is probably the 2 keys that the messge is under
Yay!

I had the same problem. The screen protecting the fan bends into the fan from the heat. Take off the top front control panel (3 screws), reach in to the back where the fan is and push the screen back away from the fan. As always, turn the power off first to avoid shock. This should solve your noise problem.

3 to 4 hours is a long time. Get to the fans (behind the control panel) and check the screens for dust. Chances are the screens are clogged with dust and need to be cleaned so the fans can move air for cooling better. I had this problem on my GE JTP14, and after cleaning just one fan it can keep up with cooling the electronic area while the oven is running. It runs much less often.

Safety first! cut the breaker before removing anything with a nice conductive screwdriver! Hope this helps!
