3. Open and close the door several times to ensure it
closes smoothly and the door actuator (Item 47)
clears the slot in the flange. Reference Figure 29.
The actuator must not hang or rub the opening
or flange. Carefully bend to clear opening.
4. While the oven door is closed, verify that the
bottom of the toggle is 85
º
to the bottom of the
frame (Figure 29). If not, use items 75 and 76
(page 42) to achieve proper angle.
5. Temporarily adjust the primary and secondary
interlock switches by loosening the #8-32 screw
(Item 49) and the two (2) #4-40 screws (Item
50). Figure 29.
6. Rotate the interlock switches (Item 51) until the
gap between the switch paddles and the switch
body is 0.02” (0.5mm). Figure 29.
7. Restore power to the oven. Allow the oven to
warm to its set temperature.
8. Allow the oven to remain at the set temperature
for ten (10) minutes after warm up before making
any final adjustments, which may be needed
because the door can move as a result of temper-
ature change.
9. Securely tighten Items 49 and 50 after any final
adjustments have been made.
10. Complete the steps for measuring RF leakage
found on page 31. Make further adjustments if
necessary.
NOTE
: High-temperature grease (Item 62) must be
present between the torsion spring and the switch
bracket assembly to ensure smooth action.
