6)Make sure the "GM" LED is on. There is a delay of at least 30 seconds before the "GM" LED turns on after power‑up. After the "GM" LED turns on, press the "SERVICE" button located on CB to bypass the 5-minute ice purge cycle. WARNING! Risk of electric shock. Care should be taken not to touch live terminals. The "COMP" LED turns on.

7)Press the actuator paddle located in the top of the chute.

S1 dip switch 7 in the "ON" position: Comp and GM de‑energizes within 10 seconds

and CB sounds a 9‑beep alarm. S1 dip switch 7 in the "OFF" position: Comp and

GM de‑energize within 10 seconds. Diagnosis: If MBC does not open or the icemaker continues to make ice, check that the actuator paddle is moving freely. Confirm that the actuator paddle is engaged. Check for continuity across MBC wires. If MBC contacts are found open and the icemaker continues to make ice, CB is bad and must be replaced. If MBC is closed with the actuator paddle engaged, MBC is bad and must be replaced.

8)Move the power switch to the "OFF" position, then unplug the unit from the electrical outlet.

9)Replace the chute assembly and strap in their correct positions.

10)Replace the control box cover and top panel in their correct positions.

11)Plug the unit into the electrical outlet.

12)Move the power switch to the "ON" position to start the automatic icemaking process.
