ADJUSTING THE PRIMARY INTERLOCK SWITCH -

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):

NGCD(5 thru 9)XXXX (North America) NGCXXD(5 thru 9)XXXX (International)

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.

Assembly Notes

1.Tip of toggle must be within window notch. Optimal is centered or below centered when the oven is hot.

2.Tip of toggle adjustment notch. Toggle must be within notch when oven is hot.

3.If toggle “hangs” in position as shown, decrease number of shims.
