TEST THE LATCH AND SWITCH SEQUENCE
(5) Open the oven door slowly. Watch the door latch
and the Secondary Switch. Release the rod and
lever on the switches to make sure they are
zero to the body of the switches in the following
sequence:
- Primary Interlock Switch
- Secondary Interlock Switch
- Interlock Monitor Switch
Adjust the latch board until the switches operate in
this sequence. See Steps 3 and 4.
(6) Close the oven door slowly and be sure it is tightly
closed. Watch the three switches to make sure
they are zero to the body of the switches in the
following sequence:
- Interlock Monitor Switch
- Primary Interlock Switch
- Secondary Interlock Switch
NOTE: The Interlock Monitor Switch is an added
safety check on the Primary and
Secondary Interlock Switches. If the
Primary and Secondary Interlock Switches
allow the oven to operate with the door
open, the Monitor Switch will blow the
fuse.
7) When you achieve the proper sequence of
switches in Steps 5 and 6, tighten the latch board
screws at that point.
TEST THE MICROWAVE ENERGY LEAKAGE
Make sure the microwave energy leakage is below the
limit of 1 mW/cm (with a 275 ml water load) and
2
5 mW/cm (with a 275 ml water load without the
2
cabinet) when measured with a survey meter.
