4055549911 Genuine Oven Thermostat 50-320C for Chef, Westinghouse, Electrolux Ovens CFE547SB CVE612SA CVE614SA CLE527WB WVG655SNG WVG665SLP

If your Chef or Westinghouse oven runs hot, burns everything or won't get up to temperature, the thermostat is worth testing. Part 4055549911 is the genuine oven thermostat with a 50 to 320 degree range. It replaces 0541001931 and 140205731015. On the Chef side it's listed for the CFE547SB, the CVE612SA and CVE614SA, and the CLE527WB, along with Westinghouse WVG615, WVG655 and WVG665 models.

Oven temperature wrong? How the thermostat works

The thermostat senses the temperature inside the cavity and switches the elements on and off to hold the setting on the knob. When it fails, the oven may overheat and burn food, stay cold, cut out far too early, or show a big gap between the dial and what an oven thermometer reads. A thermostat stuck closed can leave the elements heating non-stop, which is a safety concern, so stop using the oven if that happens. An oven thermometer on the middle shelf is the easiest way to confirm a fault.

Fitting the oven thermostat

Isolate the oven at the switchboard and let it cool. The thermostat sits behind the control panel, with its sensor running into the oven cavity, so the oven may need to come out. Note the route of the sensor and photograph the terminals before disconnecting anything. Clip the new sensor back in the same place, clear of the elements. Hard-wired appliances must be connected by a licensed electrician.

Questions about this part

Can I check the thermostat before buying?

Put an oven thermometer on the middle shelf, set the oven to 180 degrees and wait 20 minutes. A reading far above or below the setting, or an oven that keeps heating regardless, points to the thermostat.
