793291 Genuine Oven Thermostat 50 to 250 Degrees C for Fisher & Paykel Ovens, Adjustable Oven Temperature Control

Part 793291 is a genuine Fisher & Paykel thermostat with a 50 to 250 degree Celsius control range. It's the dial-set thermostat that holds the cooking temperature in ovens with knob temperature control. Thermostats with the same range can differ in shaft, probe and terminal layout, so check the number on your old thermostat, or the oven's model number and product code, before ordering.

Oven temperature wrong? Signs of a failed thermostat

An adjustable oven thermostat uses a sensing probe inside the oven to switch the elements on and off around the temperature you set on the dial. When it wears or fails, the oven might not heat at all, run far hotter or cooler than the knob says, overshoot and burn food, or keep the elements on without cycling. A damaged probe or a burnt terminal can also cause faults. Before replacing the thermostat, an oven thermometer is a simple way to check how far out it really is.

Fitting the thermostat safely

Ovens are usually hard-wired, so isolate the power at the circuit breaker and use a licensed electrician or appliance technician if you're unsure. Note how the probe is clipped inside the oven and route the new one along the same path without sharp bends. Photograph the terminals before moving wires across. Refit the knob, then check the oven reaches and holds the set temperature with an oven thermometer.

Questions about this part

How do I check if the thermostat is accurate?

Put an oven thermometer in the middle of the oven, set the dial to 180 degrees and let it preheat fully. Small swings either side are normal as the thermostat cycles. A large, consistent difference points to a faulty thermostat.
