WARNING
25. 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 clips 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 dryer while it is plugged in before handling
control to dissipate any charge.
NOTE: New control is supplied in special anti-static
packaging material. While holding control by its
metal edges, remove control from packaging
material.
a. Unlock control panel. See Figure 8A.
b. Pull top of control panel away from control
cabinet and lift up. See Figure 8B.
c. Remove control panel from control cabinet. See
Figure 8C.

disconnect blocks from backside of electronic
control assembly.
e. Remove ground clip holding ground wire to
control panel. See Figure 9.
NOTE: Refer to appropriate wiring diagram when
reconnecting wires.
NOTE: DO NOT pull on wires. Instead, hold board
near appropriate disconnect block and unplug by
pulling in disconnect block.
f. Remove four screws holding electronic controls
assembly to backside of control panel.
g. Place the old control in the anti-static
packaging material that the new control was
supplied in.
h. 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.
i. 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 packaging material which was
removed from new control. If control is not
