Upper Heater and Oven Cavity TCOs

The TCOs automatically shut off the oven in the event of excessive temperatures. When replacing, be sure to determine the cause of failure. If a TCO opens, it will disable all oven functions except the oven light. The outer cover must be removed to access the TCOs. (See Oven Removal / Partial Removal.)

•The upper heater TCO is mounted on the heat shield above the upper heater assembly.

•The oven cavity TCO is mounted to the exhaust duct on the left side of the oven.

•Both TCOs are held in place by a singe Phillips- head screw.

•Both TCOs open at 293°F and cannot be reset.
