Ran the self cleaning cycle and now the preheat light will not turn off when it gets to the temperature I set it to. It just keeps preheating. Example: I set the oven for 375. It seemed like it had been preheating for a long time so I figured it was about ready to turn off so I put my lasagna in. In about 5 minutes I heard it bubbling over, opened the oven and all the cheese was burnt. I looked and the preheat light was still on and it must have been about 500 degrees in there. So it just keeps preheating and doesn't stop at the set temp.

SOURCE: Oven does not maintain temperature while cooking.

Is this a gas unit? If so you might have a weak oven igniter.

SOURCE: 5 yr old Jenn Air Electric oven won't maintain oven temperature

Technician just left our house with same issue. Jenn-Air had issued a technical bulletin as the temperature probe is mounted directly to the heating element, and measures the heat of the element, not the oven. Their fix is a revised temperature probe that goes at a 90 degree angle away from the heating element.

If your temperature is consistent, just off by a set amount of degrees, there is an adjustment you can make at the control panel.

SOURCE: I have a KitchenAid double oven with convection on

it will either be the sensor or the board,hopefully it's not the board,the part number for the sensor is 4455636 and subs to w10131825,the sensor is around 100 bucks,there should be a tech sheet on the machine most likely behind the touch pad on the top,it will tell you how to check the sensor with a meter,just unplug the sensor and read it out i think it's around 1100 ohms but check that on the tech sheet,if it's not the sensor most likely it will be the board part number 4453661 and that's around 300 buckseverything runs through this computer board but the sensor tells it how hot it is in the oven hopefully you have a bad sensor.let me know what you find,you'll most likely have to pull the oven to repair it but maybe just enough to get the top open,good luck

SOURCE: When using the BAKE setting,

more than likely there is an issue with one of the temp sensors. you will need to press and hold clear then upper on off at the same time then release them then immed. press clear 3 times and hold on the 3rd till the service screen appears. on the right side you will see internal temp and catalyst temp they should be equal or very close. ill bet one of them is alot higher than the other if so the sensor will need replace but depends which one is bad as there are 2 of them. if the problem is on the lower just repeat above but use lower instead of upper

SOURCE: We have a model #

Hello & Welcome to FixYa

It indicates an open/shorted oven temperature sensor and to solve this problem the temp.sensor needs replacement. If you want to be sure before replacing the sensor then you can test it with a voltmeter for around 1100ohms....if it reads more then this then it needs replacement however, if the reading is around or less then 1100ohms then it is the control board that needs replacement. Please get back to me if you have any other questions.
