After the adjustment, make sure to perform the following test. This test should only be performed by authorized
service personnel.
(1) The in and out play of the door must be less than
0.5mm when latched. First check the latch board-U
position, pushing and pulling the upper portion of
door toward the oven face. Then check the lower
portion of door toward the oven face. Both results
should be less than 0.5mm.
(2) Make sure the door latch closes the monitor switch
and oven lamp switch after the primary switch is
open.
NOTE: A MICROWAVE ENERGY LEAKAGE TEST MUST ALWAYS BE PERFORMED WHEN THE UNIT IS
SERVICED, FOR ANY REASON.
This (COM-NO) test should be performed with the
door being opened very slowly.
(3) Re-install the outer case and check for microwave
leakage. Makes sure the microwave leakage is
below the limit of 4mW/cm
load.)
