Built as the cooker thermostat for a mix of Electrolux and Westinghouse ovens, part 4055918926 is genuine and cross referenced to 50281180005 and ET482081. It's listed for the POH967S, the EOB9730X and the EOQ995X, as well as the DSK965SNG and DSP963SNG, the EP900BSX and the IOS6SE2.

Signs your oven thermostat is failing

The thermostat holds the oven at the temperature set on the dial. Most cooker thermostats use a sensing bulb in the cavity, joined by a thin capillary tube to the switch body, and as the oven heats the contacts open to cut the elements. When the thermostat drifts, food burns or takes far longer than the recipe says. If the contacts weld closed the oven overheats, and if they fail open it won't heat at all. A cracked or kinked capillary is a frequent cause, and an oven thermometer is the easy way to check what's really happening.

Replacing the thermostat

This job involves mains wiring, so isolate the oven at the switchboard and have a licensed electrician fit it. Before removing the old thermostat, photograph the terminals and, if it has a capillary tube, note how it's routed and clipped to the oven cavity. Feed the new bulb along the same path without sharp bends, then check the oven with a thermometer once it's running.

Questions about this part

How do I know the thermostat is the problem?

Put an oven thermometer in the centre of the oven, set the dial to 180 degrees and wait. A reading well above or below that, or no heat at all with working elements, points to the thermostat. A technician can confirm it.
