Question about Kenmore 96222 / 96224 / 96229 Electric Kitchen Range
My stove is 3 years old. The oven temp never seemed quite right, but I just recently put a thermometer in the middle of the oven. What I found was that it would preheat and hold a temp of 350, but when I increase the temp to 400, the max it reaches is 385. When I turn it up to 450, the actual temperature slips to 375. Then a let it cool and tested again - this time preheating directly to 450. When the preheat ended, actual temp was 350. 15 minutes later it got up to 375. It seems to me this has to either be a bad sensor or a faulty computer. Any thoughts?
Brad, your right on track. But I'd look toward the sensor first (The computer only does what the sensor tells it to do). I'll need the model number to find part numbers to help you further. The model number is on a sticker located on the oven body behind the lower drawer. It'll start with 3 digits then a decimal point the more digits (xxx.xxxxxxxx).

A thermistor is a thermal resistor. It has either a positive or a (usually) negative temperature coefficient which means the resistance goes down as the temperature goes up. They are nonlinear, losing response (the curve flattens) as the temperature goes, making them less sensitive at higher temperatures. If you have replaced the sensor already, the problem is most likely with the power supply to the sensor or with the setting of the device used to determine when the oven has reached the set temperature. Thermistors usually are placed in series with another resistor whose value is not supposed to change with temperature, usually found near the back of the unit. You may have a bad resistor inline with the thermistor or have bad connections or a bad power supply.

The main problem is the manufacturer's fault in the setting accuracy of the temperature, i mean when the manufacturer has to adjust the temperature into the required temp it does not set to the required one. This is called "calibration" in engineering, the best for you is to tell the manufacturer to replace or keep it.

Also check all seals on the door are secure this problem will stop it reaching maximun temeratue i think the main problem is to do with your thermister replace this and you should find your problem solved SolutionGuy has given you the problem in great detail and i think he is bang on on the fault.
The problem i had was that my door seal had gone and this caused the themsistor to fail as the oven was continuesly heating all the time but wouldnt reach temerature i needed as the seal was allowing heat to escape.
SolutionGuy has given in great detail the answer so do this first then check the temperature of the oven and see if you are losing heat through the seal if it is you might find that the oven cools down to quick making the thermistor work more to keep the oven up to temperature hope this is some help to you ok
