What a disc thermostat does in an appliance

A disc thermostat is a small temperature switch. A metal disc inside it flicks over at a set temperature, opening or closing the circuit it's wired into. Appliance makers use them to cycle heating, switch on cooling fans, or cut power if something gets too hot. When one fails it can stick open, so the heat or fan never comes on, or stick closed, so the appliance runs hotter than it should or trips out. A multimeter test across the terminals at room temperature is a quick first check.

Swapping the thermostat safely

Turn the appliance off at the wall and let it cool before opening any panels, and get a licensed electrician to do the work if the appliance is hard-wired. Photograph the wiring and label each lead before unplugging it. Make sure the new disc sits flat against its mounting surface so it senses the temperature properly, then refit the terminals firmly and test the appliance through a full cycle.
