Lid Switch
The lid switch is installed in the cover assembly at
the right front corner of the lid recess. The switch is
held to the underside of the cover by a latch.
The lid switch is a safety feature that prevents the
washer from agitating or spinning when the lid
is open. The switch is closed by a magnet that is
attached to the lid. When the lid is shut, the magnet
will cause the switch to close the circuit, allowing
normal functions to occur. When the lid is opened,
the switch will open the circuit, which will prevent
agitating 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, but
the washer will continue to count down, fill with
water and drain at the appropriate times in the
cycle.
Was opened during a cycle, left open and the
timer finished 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 automatic temperature control
(ATC) will remain activated. The temperature of
the water entering the washer with the lid open
may vary greatly, due to the cycling of the fill
valve solenoids.
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.

Lid Switch
Note:
Lid switch openings are not retained in memory
if power is interrupted.
The main control does not monitor the lid switch.
The motor inverter control monitors lid switch
operation by monitoring voltage through pin 6
on connector C2.
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 it is necessary to open the
lid and reach under the cover assembly. To release
it from the cover requires pressing the lid switch
latch in firmly and gently pushing the switch up. The
switch can then be lifted through the opening.
