Control Replacement - ALLIANCE AA9231 Service

Section 8 Service Procedures Unique to the Electronic Control Model Washers
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the washer before servicing.
• Never start the washer with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the washer is properly grounded.

71. CONTROL REPLACEMENT

When a problem with the electronic control is
detected during the diagnostic cycle or while
making the electrical tests discussed, the control
should be replaced. Due to the sensitivity of the
electronic control, careful handling is required. As
a precautionary measure, the use of a grounded
wrist strap when handling the control is
recommended. The wrist strap, cord and alligator
clip are designed to carry away any electrostatic
charge from your body and direct the charge to an
available ground. By using this static protection
device, potential electrostatic discharge problems
associated with the handling of the electronic
control will be minimized. Always handle the
electronic control by the metal edges. If a wrist
strap is not available, touch the washer while it is
plugged in before handling the control to dissipate
any charge.
To replace the control, first unplug the washer.
Remove all of the wires connected to the control
and take out four screws securing control to
control hood. When removing wires from the
control, hold down on the board near the
appropriate terminal and disconnect the wires
using a pliers. Do not pull on wires.

WARNING
The new control is supplied in a special anti-static
wrapping, and protected by anti-static foam.
While holding the metal edges, remove the control
from the foam and wrapping. Place the
inoperative control on the anti-static wrapping.
Before positioning the new control in the control
hood, peel off protective plastic coating from the
front side of the control, then fasten control with
four screws. Following the wiring diagram,
reconnect the wires to the new control. Replace
hood.
It is important to take care when handling the
original control. It must be carefully placed in the
anti-static wrapping and foam. A copy of the
checklist, shown on the following page, must be
completely filled out and returned with the
control. Warranty credit will be issued only if the
control is handled and packaged properly.
