Maytag LAT8014 - Lid Switch Assembly (Microprocessor Models)

spin. This lid switch assembly
addresses that type of failure.
If the lid switch sticks closed even as
the
lid switch/unbalance lever releases
the button then the check switch will
still break the circuit to the timer as the
check switch button is activated by the
lid switch/unbalance lever. This will
stop the washer. As a method of calling
attention to a stuck lid switch, a fuse in
the washer's fill circuit will be blown. If
pressure switch is not satisfied, it works
this way:
As the check switch button is actuated,
it not
only opens the power line circuit
to timer, it also transfers that line power
to line fuse wired in the neutral side of
the fill circuit. If the water level control
is
in the empty position, a circuit is
made
from the lid switch through the
check switch to the fuse from line one.
The
neutral side of the line is made to
the fuse through the pressure switch to
the fuse and the fuse opens. The
washer is effectively put flout of service"
as it will not fill for the next fill opera-
tion.
Microprocessor Models
The lid switch assembly consist of only
a lid switch mounted on a bracket
secured to the top cover. It uses the
same bracket and plunger as the timer
models.
Except
for operation during the first fill,
the machine will not operate with the lid
open. The lid is checked at least once
every 25 milliseconds during washer
operation. If an open condition is
found, the machine goes into a pause
mode with "Lid" in the display.
The microprocessor board monitors the
lid switch to make sure the switch con-
tacts
open when the lid is raised (the
check switch and fuse are not used on
this model). The lid must be opened
between programs to implement this
test. If this does not occur a "lid" will
appear in the display when the next
program is selected. This must be
cleared by lifting the lid before a
program is selected. If opening the lid
does not clear the "lid" from the
display, assume the lid switch has
failed and replace.
Note: The test does not occur if the
cycle is ended by the pressing of the
"off" key, only if the cycle ends
naturally.
Remove lid switch:
1. Disconnect washer from power
supply.
2. Remove the two inside screws on
control panel
and tilt forward.
3. Remove wires on lid switch.
4. Remove the two screws securi ng the
lid switch to mounting bracket.
5. After replacing lid switch, adjust
mounting bracket so lid switch will
open when lid is raised not more
than 1 3/4".
6. Place a 1 inch block between the lid
and the washer top. This needs to
be located at the front of the lid.
7. Slide the lid switch assembly ahead
until a clicking noise is heard from
the lid switch.
8. At this point, slide the mechanism
slowly back until a clicking noise is
again heard from the lid switch (hold
in that location).
9. Lock the mechanism in place with
the mounting screw and the lid
