This section contains information about the
following components:
- Oven door
- Interlock switches
This section also contains procedures for:

- Removing/reinstalling the oven door

- Adjusting the oven door

- Adjusting the primary, secondary, and monitor
switches
- Measuring RF leakage for microwave safety
For information on accessing and removing parts,
see the Appendix.
The oven door assembly consists of a shunt plate,
skin, and handle. Each of these items can be
serviced and replaced independently.
NOTE: The proper fit and adjustment of the
oven door is essential for safe and reliable
oven operation.
Removing/Reinstalling the Oven Door
To remove or reinstall the oven door, follow the
steps below. For illustrations, see page A-2 of the
Appendix.
1. Ensure the oven has cooled to 150°F (66°C).
2. Open the oven door to its full open position
and insert rivets, screws, or nails as shown in
Figure 27 to hold the hinges in the open
position.
3. Remove the plastic caps and inset
screws (2 per side). This will allow the hinge
blocks to be removed together with the door.
4. If removing the door without the hinge
blocks, remove the #8-32 screws (3 per side).
5. Carefully remove the oven door by pulling it
away from the oven.
6. Reinstall (or replace) the door and/or hinge
blocks, verifying that the door is parallel to the
oven frame. If it is not parallel, adjust the door
per the adjacent instructions.
7. From Test Mode, check the status indicators
"P" "S" and "M" to verify the switches engage
(door closed) and disengage (door open)
properly. If they do not, adjust the switches
per the instructions on page 21.
8. Complete a microwave leakage test (page 22).

Adjusting the Oven Door
WARNING: This procedure is performed
while the oven is hot. To avoid burns, be
careful when adjusting the door.
1. Open the door and remove the plastic caps.
2. Ensure that the 3 screws on each side of the
door are tight.
3. Loosen the hex screws and close the door.
4. Tap the center of the door to allow door and
frame to align properly. The hinge springs
will pull the door to the frame; do not push
on either side, rather only in the center.
5. Tighten the screws and reinstall the caps.
6. Plug in the oven and perform a microwave

leakage test (see page 22).
Critical Adjustment Notes
If the top or bottom of the door is rotated away
from the oven cavity frame, the door is misaligned.
Corrective Action
1. Loosen the hex screws and push the door
towards the flange.
2. The hinge springs will naturally pull the door
to the flange. Tap the center to ensure a level
surface and proper seal.
