Whirlpool oven burner wont shut of after it reaches the set temp

SOURCE: Magic Chef Oven lights and shuts off

This could be caused by a lack of air within the oven cavity, once the air is used up the flame will go out, it will then work again once it is relite, but will probably do the same again, this could be dangerous and requires on site proffesional attention. Regards Engineer

When the oven safety valve refuses to open and let gas through, it's almost always because not enough current is flowing through the ignitor. Often an aging ignitor will appear to be glowing pretty brightly but still won't draw enough current to make the valve open. The first thing to try replacing is the ignitor.

You describe your ignitor as "red and glowing" but oven ignitors normally get a lot brighter than "red" -- well into what I'd call yellow.

Go to Calibration mode and adjust the temperature up by 10, 20 or 30 degree. This is in each manual.
