1. Disconnect the power supply cord and remove the oven
from wall and remove outer case. (Refer to procedure of
"Removal of Oven from Wall" and "Outer case Removal")
2. Open the door and block it open.
3. Discharge high voltage capacitor.
4. Remove the control panel assembly, referring to the
procedure of "CONTROL PANEL ASSEMBLY ,
CONTROL UNIT AND KEY UNIT REMOVAL".
5. Remove the two (2) screws holding the latch hook to the
oven cavity front flange.
6. Remove the latch hook from the oven cavity front flange.
7. Disconnect the wire leads of each switch.
8. Remove each switch from the latch hook by pushing the
one (1) stopper tub holding each switch.
9. Now, each switch is free.
Re-install
1. Re-install each switch in its place. The secondary
interlock switch is in the lower position, door sensing
switch is in the upper position, the third door switch is
in the upper vertical position and the monitor switch is
in the middle position.
2. Re-connect wire leads to each switch. Refer to pictorial
diagram.
3. Secure the latch hook (with two (2) mounting screws) to
oven cavity front flange.
4. Make sure that the monitor switch is operating properly
and check continuity of the monitor circuit.
Refer to
chapter "Test Procedure" and "Adjustment procedure".
1. Disconnect the power supply cord and remove the oven
from wall and remove outer case. (Refer to procedure of
"Removal of Oven from Wall" and "Outer case Removal")
2. Open the door and block it open.
3. Discharge high voltage capacitor.
4. Remove the control panel assembly, referring to the
procedure of "CONTROL PANEL ASSEMBLY ,
CONTROL UNIT AND KEY UNIT REMOVAL".
If the door sensing switch, secondary interlock switch and
monitor switch do not operate properly due to a
misadjustment, the following adjustment should be made.
5. Loosen the two (2) screws holding latch hook to the oven
cavity front flange.
6. With door closed, adjust latch hook by moving it back
and forth, and up and down. In and out play of the door
allowed by the upper and lower position of the latch hook
should be less than 0.5mm. The vertical position of the
latch hook should be adjusted so that the door sensing
switch, secondary interlock switch and third door are
activated with the door closed. The horizontal position
of the latch hook should be adjusted so that the monitor
switch is activated with the door closed.
7. Secure the screws with washers firmly.
8. Check all of the switches operation. If any switch has not
activated with the door closed, loosen screw and adjust
the latch hook position.
After adjustment, check the following.
1. In and out play of door remains less than 0.5mm when
DOOR SENSING SWITCH, SECONDARY INTERLOCK SWITCH, THIRD DOOR SWITCH AND MONITOR SWITCH ADJUSTMENT
in the latched position. First check upper position of latch
hook, pushing and pulling upper portion of door toward
the oven face. Then check lower portion of the latch
hook, pushing and pulling lower portion of the door
toward the oven face. Both results (play in the door)
should be less than 0.5mm.
2. The door sensing switch, third door switch and secondary
interlock switch interrupt the circuit before the door can
be opened.
3. Monitor switch contacts close when door is opened.
4. The contact of door sensing switch and secondary
interlock switch open within 1.2mm gap between right
side of cavity face plate and door when door is open.
5. Re-install outer case and check for microwave leakage
around door with an approved microwave survey meter.
