Pull oven out away from the wall, unplugged from outlet, removed center cover by removing 5 sheet metal screws. disconnected thermostat sensor from control cable. Opened oven door and removed screw that holds thermostat sensor. Pulled thermostat sensor out replaced with new sensor. Plugged sensor in to control cable. Replace panel and screws. Then my wife made me clean the oven. I recommend making the repair when your wife is not home.
Oven Temp. went too high and the door locked. Burnt the food
This temperature sensor is very easy to replace. There are two screws inside the oven in the top middle of the back of the oven. Take these off. on the back of the stove there is a metal plate with 5 screws I believe. Take these off with a nut driver. Then you will see a white connector coming from the spot where you took the other screws off. Take the white connector apart and pull out the temperature sensor from the inside of the oven. Then put the new one in.
Flip toggles to release the oven door. Pull up on oven door to remove. Put door aside. Lift enamel bottom. Slide strait out. Remove aluminum shielding from around the igniter. Loosen igniter, unplug the igniter. Remove burner cowling. Plug in new igniter. Attach cowling to new igniter. Screw it all back in place. Stuff wiring connected back through the protective hole. Depress close door button and test. It takes about 10-15 seconds to ignite. Reinstall aluminum protector. Re install bottom enamel piece. Carfully slide oven door back on pegs and flip toggles to lock. Have a big glass of water and yell, Honey I fixed the oven!!
Could not have been easier. All screws are 1/4 inch. Oven door can be removed to make it easier to get to screws in back of oven,but igniter can be installed with door in place. Remove bottom panel then remove four screws on flame spreader. Remove trwo screws that hold igniter in place. Replace with new igniter, it may be necessary to remove the clip on new igniter and splice the two leads. Now your cooking with gas.
Removed screws holding temp sensor, pulled wire out from behind wall until found connector, disconnected old sensor. Measured resistance of old sensor and compared with new sensor, they measured nearly the same. Installed the new sensor and tested the stove. Came up to temp ok. No problem since, about 2 weeks.
I picked the least expensive and most likely issue with our oven that was not indicating a correct oven temperature. I am sure with a 15+ year appliance that the circuitry is on its way out but wanted to give this a try to avoid a new appliance purchase. Oven pre-heat setting takes much longer to finish with the age of the oven. However, after the new sensor the oven will maintain a more even temperature for the cycle.
Removal of the sensor from the inside of the oven is a bit awkward since it is located between the broiler elements at the back but a nut driver was the correct tool and worked fine. A bit stuck with the heating of the connection but pretty simple to replace. Must remove the back first to uncouple the connector. Simplest part of the repair.
At best a temporary fix for a an appliance this old.
I did find instruction in the Q&A on how to to change the part was for an older oven.
Here are the instructions that matched my oven model "JGSP42SET1SS"

I also had issues where the connector for the new part would not come through the hole in the back of the oven. I used a shoestring around the connector so I would have a good grip on it when I disconnected the old igniter.This allowed me to have a good grip to reconnect to the new igniter.
While you have this apart I would also recommend that you remove the burner and blow out any material that may have accumulated over the years,
The repair was very easy to do. Our oven was showing the F2 error code, which is associated with an over-temperature fault. Upon inspection, the oven was warm, but definitely not beyond the temperature threshold. I researched the issue and found this temperature sensor. Swapping the sensor was extremely easy. You take off the back panel of the oven, unhook a single wiring harness, and undo some bolts inside the oven, which allows you to pull off the old sensor. Simply hook up the new sensor to the harness, pull everything back through, replace the fasteners, and you're good to go.
