3.Secure latch hook (with two (2) mounting screws) to oven flange.

4.Make sure that the monitor switch is operating properly

and check continuity of the monitor circuit. Refer to chapter "Test Procedure" and Adjustment procedure.

DOOR SENSING SWITCH/PRIMARY SWITCH/SECONDARY SWITCH AND MONITOR SWITCH ADJUSTMENT

1.Disconnect the power supply cord, and then remove outer case.

2.Open the door and block it open.

3.Discharge high voltage capacitor.

If the door sensing switch, primary switch, secondary switch and monitor switch do not operate properly due to a misadjustment, the following adjustment should be made.

4.Loosen the two (2) screws holding latch hook to the oven cavity front flange.

5.With door closed, adjust latch hook by moving it back and forth, and up and down. In and out play of the door allowed by the upper and lower position of the latch hook should be less than 0.5mm. The vertical position of the latch hook should be adjusted so that the door sensing switch, primary switch and secondary switch are activated with the door closed. The horizontal position of the latch hook should be adjusted so that the plunger of the monitor switch is pressed with the door closed.

6.Secure the screws with washers firmly.

7.Check the operation of all switches. If each switch has not activated with the door closed, loosen screw and adjust the latch hook position.

After adjustment, check the following.

1.In and out play of door remains less than 0.5mm when in the latched position. First check upper position of latch hook, pushing and pulling upper portion of door toward the oven face. Then check lower portion of the latch

hook, pushing and pulling upper portion of door toward the oven face. Both results (play in the door) should be less than 0.5mm.

2.The door sensing switch, primary switch and secondary switch interrupt the circuit before the door can be opened.

3.Monitor switch contacts close when door is opened.

4.Re-install outer case and check for microwave leakage around door with an approved microwave survey meter. (Refer to Microwave Measurement Procedure.)

15.Now, latch head and latch spring are free. 16.Remove door screen from door frame 17.Now, door frame is free.

RE-INSTALL

1.Re-install door screen to door frame.

2.Re-install the latch spring to the latch head. Re-install the latch spring to the door frame. Re-install latch head to door frame.

3.Re-install door panel to door frame by fitting twelve (12) tabs of door frame to twelve (12) holes of door panel.

4.Put sealer film on door panel. Refer to “Sealer Film” about how to handle new one.

5.Catch two (2) pins of door panel on two (2) hole of upper and lower oven hinges.
