Noticed food scorching in oven during a normal bake. Hit "Cancel" but oven stayed on. No error codes on display and correct setpoint temperature was indicated on display.

Everytime I plug the Range back in the oven comes on by itself about 30 seconds later and just keeps heating up. Again , no error codes are displayed on control panel.

I did pull the temperature sensor as advised on another forum. It measures 1090 Ohms at room temp and increases resistance with temp. I checked to see if anything changed with moving wires and the connector and found no problems.

If I turn the broiler on using the control panel the oven burner does shut off and the broiler burner comes on. As soon as I turn the broiler off, the oven lights up again.

If I try to set a bake temperature everthing looks normal, except the actual temperature of the oven just keeps going up..ie set for 325 and it goes up to about 500 ( measured using seperate oven thermometer inside ).

Is there a replaceable relay for oven control that might be stuck in the "on" position ?

Any help would be appreciated, Thanks
