Magnetron and Magnetron TCO

WARNING: Always be certain the capacitor is discharged before servicing. (See Capacitor and Diode.) Mechanically discharge by placing an insulated handle screwdriver between the diode connection of the capacitor and the oven chassis ground.

Note: The capacitor has an internal discharge resistor that automatically discharges the capacitor when the oven turns OFF. Under normal operation, the capacitor should fully discharge within 30 seconds.

The oven must be removed to access the magnetron. (See Oven Removal / Partial Removal.) The magnetron is located behind the top access cover. The top access cover is held in place by 2 Phillips-head screws. The magnetron is held in place by 4 Phillips-head screws. The magnetron thermostat must be disconnected before removing the magnetron.

Magnetron TCO

Magnetron TCO

The magnetron TCO is attached to a bracket mounted to the magnetron. The magnetron bracket is held in place by a single Phillips-head screw.

This position of the magnetron TCO allows it to sense the temperature of the magnetron.

The magnetron TCO opens at 302°F and cannot be reset. If the magnetron TCO opens, it will disable all oven functions including the display.

High Voltage Transformer

WARNING: Always be certain the capacitor is discharged before servicing. (See Capacitor and Diode.) Mechanically discharge by placing an insulated handle screwdriver between the diode connection of the capacitor and the oven chassis ground.

Note: The capacitor has an internal discharge resistor that automatically discharges the capacitor when the oven turns OFF. Under normal operation, the capacitor should fully discharge within 30 seconds.

The oven must be removed to access the high voltage transformer. (See Oven Removal / Partial Removal.) The high voltage transformer is located behind the top access cover. The top access cover is held in place by 2 Phillips-head screws.

The transformer is held in place with 4 Phillips-head screws. Two of the screws are recessed from the top of the outer cover. Access holes are provided. A magnetic screwdriver is necessary to capture these screws.
