e. ELECTRONIC CONTROL
IMPORTANT: Due to the sensitivity of the
electronic control, careful handling is required. As a
precautionary measure, we recommend using a
ground wrist strap when handling the electronic
control. Wrist strap, cord and alligator clip are
designed to carry away any electrostatic charge
from your body and to direct charge to an available
ground. By using this static protection device,
potential electrostatic discharge problems
associated with handling of electronic control will
be minimized. Always handle electronic control by
its metal edges. If a wrist strap is not available,
touch washer while it is plugged in before handling
control to dissipate any charge.
NOTE: New control is supplied in a special anti-
static wrapping, and protected by anti-static foam.
While holding control by its metal edges, remove
control from foam and wrapping.
(1) Remove two control panel attaching
screws. Refer to Figure 5. Lay control
panel assembly face down on protective
padding.
(2) Press in on locking tabs and unplug harness
disconnect blocks from backside of
electronic control assembly. Refer to
Figure 8.
NOTE: DO NOT pull on wires. Instead, hold board
near appropriate disconnect block and unplug by
pulling on disconnect block.
(3) Remove four screws holding electronic
control assembly to backside of control
panel. Refer to Figure 8.
(4) Place the old control in the anti-static
wrapping that the new control was supplied
in.
(5) While holding new control by its metal
edges, carefully peel off protective plastic
coating from front side of control. Then
place control in opening of control panel
and fasten control down with four screws.
(6) Follow wiring diagram and reconnect wires
to new control.
IMPORTANT: It is important to take care when
handling the original control. It must be carefully
placed in the anti-static wrapping and anti-static
foam which was removed from new control. If
control is not wrapped properly, warranty credit
will not be issued.
