Maytag UMV1152CA manual Magnetron Fan Assembly Removal, Magnetron Thermal Fuse Removal

Disassembly Procedures

!WARNING

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.

!WARNING

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

Fan Motor

Humidity Sensor Removal (Select Models)

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

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.

NOTE: Lift upward on left rear corner of air duct to release oven thermostat.
