ADJUSTING THE MONITOR SWITCH - OLD SETUP
The old switch assembly is identifiable by the moni-
tor switch being located on the right hinge assembly.
Also, the serial number of the oven will follow this
formatting (X = variable digit/letter):
NGC-XXXXX (North America)
NGCXX-XXXXX (International)
To adjust the switch, follow the steps below.
1. Ensure the oven door is adjusted. Refer to
ADJUST-
ING THE COOK DOOR
on page 38.
2. Turn on oven and bring it to the set temperature.
WARNING: Oven surfaces are HOT! Use
extreme caution when making adjustments.
3. Open and close the oven door several times to
ensure the door closes smoothly and the door
actuator (Item 47) clears the slot in the flange.
Reference Figure 29.
4. Disconnect oven from power source.
5. To adjust the monitor safety switch (Figure 31),
loosen the #8-32 screw and the two (2) #4-40
screws (Items 68 and 69) securing the switch.
6. Rotate the monitor safety switch (Item 65) until
the gap between the switch paddle and the switch
body is 0.02” (0.5 mm).
7. Open and close the oven door several times to
make certain the adjustment is correct.
8. Tighten all screws.
9. Reconnect oven to power source.
10. Allow oven to sit at the set temperature for 10
