NEW SWITCH SETUP
The new switch assembly is identifiable by the pri-
mary switch being located on the left side of the
oven. Also, the serial number of the oven will fol-
low the formatting below (X = variable digit/letter):

1. When the oven completes
BURN IN (if
required, see page 38), closely examine the latch
toggle position using the door switch gauge
(Item 75).
2. If the toggle is past the top of the window, you
must correct the toggle's position by installing
an 0.030” Shim (Item 76). See Figure 32.
3. Verify position of toggle by opening and closing
the oven door.
4. With the toggle correctly adjusted and the door
closed, adjust the primary switch by loosening
the two #4-40 screws and #8-32 screw.
5. Using a 0.030” (0.762 mm) spacer as a template
(included with Item 74), adjust switch lever
position to a maximum allowable distance of
0.030” (0.762 mm).
6. Open and close the door several times to verify
the switch gap.
