Bottom Thermal Cutout (TCO)

The bottom TCO is located on the bottom, right side of the oven behind the control panel. The bottom TCO is not resettable.

The bottom TCO's contacts open at approximately 248°F.

To remove the bottom TCO:

1.Remove the control panel assembly. (See Control Panel Assembly.)

2.Disconnect wiring from the bottom TCO.

3.Remove the Phillips-head screw attaching the bottom TCO to the oven, then pull the TCO forward.

Magnetron Thermal Cutout (TCO)

The magnetron TCO is located on the magnetron and opens when the magnetron temperature reaches 302°F.

The magnetron TCO is a normally closed switch. An open reading across the TCO indicates a failed TCO. The magnetron TCO resets at 140˚F.

To remove the magnetron TCO:

1.Remove the outer cover. (See Outer Cover.)

2.Disconnect the wiring to the magnetron.

3.Remove the 2 Phillips-head screws that attach the magnetron to the oven.
