a WARNING
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the dryer before servicing.
• Close gas shut-off valve to gas dryer before servicing.
• Never start the dryer with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the dryer is properly grounded.

87.CONTROL REPLACEMENT (Figure 64)
When a problem with the electronic control is
detected during the diagnostic cycle, or while
making the electrical tests we have discussed,
the control is replaced as a complete unit. Due to
the sensitivity of the electronic control, careful
handling is required. As a precautionary
measure, we recommend the use of a grounded
wrist strap when handling the electronic controls.
The wrist strap, cord and alligator clip are
designed to carry away any electrostatic charge
from your body and to 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 dryer while it is
plugged in before handling the control to
dissipate any charge.
To replace the control, first unplug the dryer.
Remove all of the wires connected to the control
and take out the screws securing the control to
the 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.
Figure 64
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 the wrapping. Lift the
inoperative control off the mounting bracket and
place it on the anti-static wrapping. Before
positioning the new control in the control hood,
peel off the protective plastic coating from the
front side of the control, then fasten the control
down with the screws. Following the wiring
diagram, reconnect the wires to the new control,
then replace the control hood.
IMPORTANT: Take care when handling the
original control. It must be carefully placed in
the anti-static wrapping and the anti-static foam
which was removed from the new control. A
copy of the replacement report, shown on Page
87, must be completely filled out and returned
with the control. Warranty credit will not be
issued if the control is not wrapped properly.
