If your Westinghouse oven has stopped heating altogether or cuts out part way through cooking, the thermal cut-out is worth testing.

These include wall ovens such as the WVE613S, the WVE626S and WVE665S, and the WVEP916SB, along with the PPN776, PSN632, PXN688 and PXR698 series.

What the oven thermal cut-out does and why it trips

The cut-out is a safety switch that opens if the area it monitors gets hotter than 145°C, cutting power before heat can damage wiring or the cabinetry around the oven. Once it trips or fails, the oven may stay completely cold, or switch off mid-cook while the controls still show as on. A cut-out that keeps tripping is often reacting to a cooling fan that has stopped, a damaged door seal or a blocked vent, so check those as well. A cut-out that shows no continuity when cold has failed and needs replacing.

Testing and fitting the cut-out

Isolate the oven at the switchboard and let it cool completely before opening any panels. In Australia, work on a hard-wired oven should be done by a licensed electrician. Test the old cut-out for continuity while cold, note which wire goes to each terminal, then fit the new one firmly against its mounting so it senses temperature correctly. Track down the cause of any overheating before the oven goes back into use.

Questions about this part

Why does my oven keep tripping the cut-out?

A cut-out that opens again and again is usually reacting to genuine overheating. Common causes are a failed cooling fan, a worn door seal letting heat out over the controls, or blocked vents. Fix the cause as well as replacing the cut-out.
