Westinghouse oven not heating or burning food

The thermostat senses oven temperature, usually through a capillary probe in the cavity, and switches the elements on and off to hold the setting on the knob. When it drifts or its contacts fail, the oven may not heat at all, run far hotter than the dial says, or cook unevenly with long recovery times after the door is opened. Burnt edges with a raw centre, or a cake that never rises, are classic clues. An inexpensive oven thermometer is a good way to confirm the temperature is off before you replace the part.

Who should fit an oven thermostat

Wall ovens and cookers are hard wired, so a licensed electrician needs to fit this thermostat. Isolate the oven at the switchboard and confirm it's dead before the panel comes off. Note how the capillary is routed and clipped inside the cavity, photograph the terminal connections, and feed the new probe along the same path. Test the oven at a couple of settings once it's running.

Questions about this part

How do I know it's the thermostat and not the element?

If the element glows or heats but the oven temperature is wrong, the thermostat is the likely cause. If the element stays cold, test it for continuity first. A licensed electrician can confirm which part has failed before you order.
