Door Sensing Switch / Secondary Interlock Switch And Monitor Switch Adjustment - Electrolux EI30SM55JB Technical & Service Manual

Door Sensing Switch / Secondary
Interlock Switch And Monitor Switch
Adjustment
1. Disconnect power cord and remove outer case.
2. Open the door and block it open.
3. Discharge high voltage capacitor.
To discharge the high voltage capacitor, wait for 60
seconds and then short-circuit the connection of
the high-voltage capacitor (that is the connecting
lead of the high-voltage rectifier) against the
chassis with the use of an insulated screwdriver.
4. Remove the right panel assembly, referring to the
procedure of "Right Panel Assembly And Power 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
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.
Component Teardown and Testing
After adjustment, check the following:
1. In and out play of door remains less than 0.5mm
when 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
upper portion of door toward the oven face. Both
results (play in the door) should be less than 0.5mm.
2. The door sensing switch, primary switch and third
door switch interrupt the circuit before the door can
be opened.
3. Monitor switch contacts close when door is opened.
4. Re-install outer case and check for microwave
leakage around door with an approved microwave
survey meter.
