Cycling the ice maker manually verifies the
motor works, the mold heater turns on and off,
the shut-off arm travels to the OFF position,
the water valve opens for seven seconds, and
the shut-off arm drops to the ON position.
Figure 10-8 illustrates the jumper wire needed
for jumpering test points L and H.
Before starting, shut off the water supply to the
water valve and make sure the AC power cord
is plugged into an energized receptacle.
To manually cycle the ice maker:
1. Remove the ice bin and freezer shelf.
2. Detach the ice maker from the evaporator
plate. Do not to pull on the wire harness.
3. Rotate the ice maker so the module cover
faces toward the freezer door, then remove
the cover.
Pull the jumper wire out when a “click”
sound is heard or no later than 15 seconds
after jumpering terminals T and H. Failure
to remove jumper wire may damage the ice
maker.
WARNING
4. Jump test points T and H. See Figure 10-9,
page 82
Figure 10-10, page 82 illustrates the cycle
events after jumpering test points T and H.
Jumpering the points bypasses the thermostat,
which causes the motor and the mold heater to
come on.
