If the light is going on...the thermostat is bad. Usually, the replacement can be gotten at any appliance parts website. You'll need a 180 degree unit. What you'll need to find inside is a unit about 5/8 inch in diameter 15mm. This has two connectors on it. Depending on the wiring, you'll likely need a low temp closed unit.
