Brian for Model Number 79096419401 My oven temp is not accurate. When you set it to 350 is goes from 300 to 375 and is not stable. The repair person said that it needed a new cpu. I see several boards for this model. Control board(316418101), Oven Control board (316557207), and a Circuit board (316429301). The TC is still good. Which board controls the heating elements based on the input from the TC?
Answer Brian, Before you do anything or repalce any parts, you should check your average oven temperature, you may only need to calibrate the control. First, get an accutate thermometer, you can place in the oven. Pre heat the oven at 400 dgrs. for at least 20 minutes. Then you'll need to listen and write: when the control clicks or notice the temp, start to rise, write down the temperature, when the control clicks or the temp. starts to drop, write down the temp. Do this at least three times. Average the temperatures, the average off temperature should be within 50 dgrs. of the on temperature and the average off temperature, should be within 25 dgrs. of the set temperature. If your averages are within the specifics, your control and temp. sensor are fine. You can recalibrate the control to within 5 dgrs. if needed or desired, without replacing anything.
