Lid Switch Assembly
The lid switch assembly consists of 2 magnetically
operated switches, enclosed in a plastic housing.
One switch controls AC voltage and the other DC
voltage.
The lid switch assembly is located under the cover/
lid assembly at the right front corner of the lid
recess. The switch assembly is held to the underside
of the cover by a latch plate and a Phillips-head
screw.
The switch assembly is a safety feature that
prevents washing or spinning when the lid is open.
Both switches are closed by a magnet attached to
the lid. When the lid is shut, the magnet will cause
both switches to close, allowing normal functions
to occur. When the lid is opened, both switches will
open, which will prevent washing or spinning.
If the lid switch:
•
Is closed, it will provide 120 VAC to the inverter/
motor assembly at pin 6 of the C2 connector.
•
Is open, agitation and spin will not occur, the
control will beep and display lid to signal the lid
should be closed.
•
Was opened during a cycle, left open and the
timer fi nished the cycle, when the lid is closed
again, the inverter completes a spin algorithm to
ensure the mode shifter is de-energized.
•
Is open, the ATC will be disabled during the time
the lid is open.
•
Opens during agitation, the control will keep
the mode shifter energized. When the lid switch
closes while still in agitation, the washer will
resume agitation.
•
Opens during the execution of the mode shifter
agitate program, the control will stop the agitate
program and drop the mode shifter voltage to
0 VDC. When the lid switch is closed again, the
control will run the mode shifter spin program
and then re-run the agitate program from the
beginning.
•
Opens during the mode shifter spin program,
the control will stop the spin program. When the
lid is closed again, the control will run the spin
program from the beginning.
Note:
•
Lid switch openings are not retained in memory
if power is interrupted.
•
As a safety measure, the inverter control
monitors lid openings by recording motor run
sequences. If the control runs 4 continuous
agitation/spin cycles (usually 2 complete wash
cycles) WITHOUT seeing the lid switch open, it
will shut down the motor and initiate a lid switch
error code. This error will prevent the motor from
operating until the problem is repaired.
To access the lid switch assembly, it is necessary
to remove the cover/lid assembly. (See
.) To release the switch assembly from the
Assembly
cover/lid assembly requires opening the lid and
pressing the lock tabs on the latch plate outward
and removing the Phillips-head screw. A plastic
compression tab attaches the switch wire harness
to the cover/lid assembly. The switch assembly can
then be removed from the cover/lid.
