(1) Disconnect all wire leads from Primary Interlock and

Interlock Monitor Switch.

(2) Pull the Primary Interlock Switch or Interlock Monitor

Switch upward at the same time while pushing the
Switch Stoppers to allow a space between the
switch body and catches.

(3) Make necessary adjustments or replacement of

switch by the reversing step (2) and check micro-
wave energy leakage according to “1. ADJUSTMENT
PROCEDURES” on page 1, after it is replaced with
new one, and check proper operation of it according
to  “CHECKOUT  PROCEDURE FOR SWITCHES” on
page 6.

Interlock Switch Replacement - when replacing
faulty switches, be sure switch mounting tabs are
not bent, broken or otherwise deficient in their
ability to secure the switches in place.

(Figures 1 on page 1, 10-a)

(1) Disconnect all wire leads from the Door Sensing

Switch. (Figure 1 on page 1)

(2) Remove 2 screws securing the Lever Stopper.

(3) Push the Door Sensing Switch upward while pressing

adjacent Upper Switch Stopper of Lever Stopper and
Lower Switch Stopper down (Figure 10-a).

(4) Then remove it by lightly pressing the switch toward

you (Figure 10-a).

(5) Make necessary adjustments or replacements of the

Door Sensing Switch by reversing step (3) and check
microwave energy leakage according to “1.
ADJUSTMENT PROCEDURES” on page 1, after it is
replaced with new one, and check proper operation
of it according to “CHECKOUT PROCEDURE FOR
