Hello all,

Last night my wife was baking and the heating (temperature dropped off).

Cooling Fan runs, On Light is functioning, I checked the heating elements up and lower with Ohm meter - zeros out - low resistance/continiuity OK.

Switch selector has a burn location on W/R wire that connects to the ON light and the On light is functioning.

The oven is clean inside the baking cavity ( We do not cook greasy stuff) - never needed the self cleaning function -yet.
Inside the electrical connection (light amount of dust) is clean.

If I just replace the selector switch, is that the cause for the no heating, or is it the relay board, thermometer(s)?

Please help. Thanks.

Jerry
