COMPONENT DIAGNOSTICS MODE CHART

COMPONENT DIAGNOSTICS MODE (RUN OPTICS DIAGNOSTICS PROCEDURE FIRST)

1. Disconnect the power supply.

2. Slide the ice maker out and remove the cover.

3. Jumper holes "T" and "H" to bypass the bimetal and start a harvest.

4. Reconnect the power supply.

5. Close the freezer door to align the optics and a harvest cycle will begin in 5 seconds.

6. Open the freezer door and observe the ice maker. A "harvest" should be in progress.

NOTE: If holes "T" and "H" are properly jumpered and the ice maker will not run, stop the test, and check the ice maker.

7. Remove the jumper before the fingers reach 10:00. Reinstall the ice maker, or be prepared to catch the water fill during step 8.

8. Disconnect power immediately after the water fill.

9. With the freezer door closed, reconnect the power supply.

10. Wait 5 seconds, to a maximum of 50 seconds, then open the freezer door, and watch the Status LED for one of the following codes.

4 PULSES, repeated once, indicates the relay is defective. Replace both the emitter and receiver boards.

3 PULSES, repeated once, indicates the optics and relay are okay, but the ice maker is not being sensed, or will not operate. If this happens:

• Check the bail arm switch to make sure it is On.

• Check the ice maker circuit and the connections back to the receiver board and neutral.

• Check the ice maker components.

2 PULSES, repeated once, indicates the optics are blocked, or defective. Clear the optics path, and repeat the "Optics Diagnostics Procedure."

Replace both boards, if necessary.

STEADY LIGHT for 5 seconds indicates the relay and optics are okay, and the receiver senses the ice maker.

NO LIGHT: Unplug the refrigerator for 5 seconds, and repeat the test.
