Switch (Stop, Monitor, Secondary Interlock) Adjustment - Wolf MWD24-2 Service Manual

Drawer Microwave
Stop Switch, Secondary Interlock Switch and
Monitor Switch Adjustment:
1. Follow the Drawer Microwave disassembly as previ-
ously stated on page 4-6.
2. Open the drawer and keep it open.
3. To discharge the high voltage capacitor, wait for 60
seconds.
4. If the door sensing switch, secondary interlock
switch and monitor switch do not operate properly
due to a misadjustment, the following adjustment
should be made.
6. Loosen the screw holding latch hook to the oven
cavity flange.
7. With drawer 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 second-
ary interlock switch is activated with the drawer closed. The horizontal position of the latch hook should be
adjusted so that the monitor switch and drawer sensing switch are activated with the drawer closed.
8. Secure the screws with washers firmly.
9. Check all of the switches operation. If any switch has not activated fully, you will need to adjust the slide rail
attached to the microwave cavity.
10. This is done by following the steps to remove the "Drawer Assembly and Drawer Support Angle Removal" on
page 4-10. After you have removed the drawer support covers, loosen the two screws holding the slide rail to
the microwave cavity and tilt the front end up and the rear end down, then tighten the screws (See Figure 4-9).
11. Check and assure that the cap nuts on the drawer support angles are centered when passing through the cavity
face plate.
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 drawer toward the oven face. Then check lower portion of the latch
hook, pushing and pulling lower portion of the door toward the oven face. Both results (play in the door) should
be less than 0.5mm.
2. The secondary interlock switch interrupts the circuit before the door can be opened.
3. Monitor switch contacts close when door is opened.
4. Door sensing switch contacts open when door is opened.
5. Reassemble the unit and check for microwave leakage around door with an approved microwave survey meter
(Refer to Microwave Measurement Procedure on page 4-4).
