COMPONENT DIAGNOSTICS MODE

WARNING
Electrical Shock Hazard
Voltage is present during these tests.
NOTE: The optics must be working properly
to test the ice maker. If the optics test fails,
you will not be able to force a harvest and check
the ice maker. Refer to the Troubleshooting
Chart on page 5-10 for additional servicing in-
formation.
IMPORTANT: If the freezer temperature is
not cold enough to allow the ice maker bi-
metal to close, a jumper must be installed
on the ice maker at test points T and H, and
the test rerun.
1.
Run an optics check as described in the
previous section.
2.
Disconnect power to the unit.
3.
Slide the ice maker out of the mounting
rails and leave the wiring harness con-
nected.
4.
Jumper the thermostat, as shown below.
5.
Connect power to the unit.
6.
Remount the ice maker, making sure that
the water fill tube is inside the fill cup.
7.
Make sure there is a clear path across the
bin for the infrared beam to travel to the
receiver sensor.
8.
Close the freezer door and wait 5 seconds
to allow the optics relay to close.
9.
Open the freezer door and you will see the
ejector bar moving. Remove the thermo-
stat jumper prior to the ejector blades
reaching the 10:00 position, or else you
will not see the water fill. The mold should
be warm due to the heater operation.
10. Disconnect the power immediately after
the water fill.
11. With the freezer door closed, reconnect
the power.
12. Wait for a minimum of 5 seconds, and a
maximum of 50 seconds, then open the
freezer door, and view the status LED for
the output codes, as shown in Chart C, on
page 5-7.
