Question about GE JTP15 Electric Single Oven
GE JTP 1580W 288
I set oven to 375 F. Lower element turn on. Oven heats to 375. At some point, upper (broil) element turns on, lower element turns off. Oven continues to heat until warning beeper and F2 error code shows.
The F2 Error code means the oven has detected an excess temperature condition. Most often this is due to a bad temperature sensor - the sensor costs about $75 from an online repair site.
How to remove and replace the temperature sensor. In most GE ovens, when you open the door, you'll see the rod-shaped temperature sensor sticking out of the back wall at the upper left. It's about six inches long and a bit more than 1/8" in diameter, held in place with two screws.
Turn off the circuit breaker (built-in ovens) or unplug the range before attempting the replacement.
The replacement sensor will come with instructions, but basically it's a matter of removing the sensor, pulling out the wires to where they are connected and disconnecting them. You may have to snip. The replacement sensor will come with high-temp wire nuts to hold the new connection. Polarity doesn't matter; it's a straight resistance thermocouple. Hook it up, be sure you poke the connections back far enough so that they're on the other side of the thermal insulation and not resting against the back of the oven.
If you continue getting the F2 error after replacing the sensor, then the problem is likely in the control module - this is the circuit board behind the keypad and clock.
You'll need to remove the decorative bezel to get behind the control panel. Remove screws and set off parts in order - it's not complicated. Once the bezel is off there are two more screws that hold the panel in place. Then you can lift the panel up about a half inch and pivot it forward toward you. You'll see a bunch of wires going to a circuit board.
On the panel you will notice some black plastic boxes that say "Potter & Brumfield" on them. These are relays. Check the relays - slide the black plastic cover straight up to expose the coil and the contacts. The coil, when energized, closes the contacts - look at all the relays. You can manually close the contacts with your finger (be gentle). If the contacts of one of them are stuck, they might be welded together. You can fix the problem by prying apart the welded contacts gently with a knife blade. Take some time to gently polish the relay contacts with a folded bit of fine grain sandpaper - this will get some more life out of them. Be gentle and careful - the relays aren't complicated but if you bend the contact or rip it out, you'll have to replace the controller, which will set you back a couple hundred dollars. If you unstick and burnish the relays, they will probably eventually weld together again as the rough spot will spark, but when you burnish them with sandpaper they should be good for some more life before they need to be replaced.
If the problem isn't the temp sensor or welded relay contacts then the problem is obviously somewhere else, but temp sensor and relay contacts will account for the lion's share of F2 errors.
Once again, be safe, be careful, be gentle. Ovens are not very complicated and they're tough, but always exercise care. Always disconnect electricity before messing with them.

Thank you for contacting Fixya.com.
First you need to check whether you are getting full 220 volts + to the oven. Some oven controls have adjustable knobs where can be fine tuned. The temperature can be calibrated by 25 degrees but not any 200 degrees. I think these can get you may be up to 75 degrees max. It seems like your sensing bulb is mounted right your oven control which has the sensing bulb attached could very well be shot. Also check if the elements work? Does the broil get red when set on broil; does the bake get red when set on bake? If yes the wiring should be ok and possibly/probably is a bad oven temp control. If the elements do not get red, that would have to be investigated (burnt wire, bad selector switch, bad oven control, burnt wire. Turn on the oven with the meter connected. It should show full voltage when you first turn it on and the thermostat will turn it on and off.
If the sensor inside the ovens baking compartment is not damaged, touching any metal part, bent, pitted, no foil is used on the racks or lower plate, in an attempt to keep ovens internal clean, etc, then temp sensor is likely defective. Which means the ECR (control unit) will need to be replaced.
Please get back to us if you have any further query.
Have a nice day.
