A microwave leakage test must be performed anytime
a magnetron assembly is removed, replaced,
disassembled or adjusted for any reason.

Magnetron Fan Assembly Removal

Magnetron fan motor provides cool air circulation from
an external air source, which provides direct cool air
through air vanes surrounding the magnetron. This
assembly is located above the magnetron.
1. Follow steps 1 through 5 of "Magnetron Removal"
procedure.
2. Remove fan blade from fan motor.
3. Remove screws securing fan motor to air duct.
4. Label and disconnect wires from fan motor and lift
assembly out.
5. Reassemble in reverse order.

Magnetron Thermal Fuse Removal

NOTE: Thermal fuse is not resettable.
1. Disconnect power to oven and remove control panel,
see "Control Panel Removal" procedure.
2. Discharge high voltage capacitor, see "High Voltage
Capacitor Removal" procedure.
3. Remove outer case, see "Outer Case Removal"
procedure.
4. Label and disconnect wire terminals.
5. Remove screw securing thermal fuse to cooling fan.
6. Replace and reassemble in reverse order.
Magnetron Thermal Fuse

Humidity Sensor Removal (Select Models)

The sensor is a plug-in device located in the air exhaust
duct.

To avoid risk of electrical shock, personal injury or
death; disconnect power to microwave oven and
discharge the high voltage capacitor before performing
any disassembly procedures.
1. Disconnect power to oven and remove control panel,
see "Control Panel Removal" procedure.
2. Discharge high voltage capacitor, see "High Voltage
Capacitor Removal" procedure.
3. Remove outer case, see "Outer Case Removal"
procedure.
4. Remove screws securing sensor to air duct.
5. Disconnect wire terminal; replace with new sensor.
6. Reassemble in reverse order.

Oven Thermostat Removal

The oven thermostat is on the air duct assembly.
The thermostat is a resettable thermostat.
1. Disconnect power to oven and remove control panel,
see "Control Panel Removal" procedure.
2. Discharge high voltage capacitor, see "High Voltage
Capacitor Removal" procedure.
3. Remove outer case, see "Outer Case Removal"
procedure.
4. Disconnect wire terminals from oven thermostat.
Fan Motor
NOTE: Lift upward on left rear corner of air duct to
release oven thermostat.
