3)Move the control switch to the "OFF" position.

4)Move the power switch to the "OFF" position.

5)Turn off the power supply.

6)Disconnect red BC connector from the back of the control box.

7)Check for continuity across BC proximity switch violet (V wire) and orange (O wire).

If BC actuator is not engaged and BC proximity switch is open, replace BC proximity switch.

8)Press and hold BC actuator paddle. While BC actuator is engaged, check for continuity across BC proximity switch violet (V wire) and orange (O wire). If BC actuator is engaged and BC proximity switch is closed, replace BC proximity switch.

9)Disengage BC actuator paddle.

10)Connect red BC connector.

11)Turn on the power supply. Move the power switch to the "ON" position.

12)Move the control switch to the "ICE" position.

13)Engage the safety switch to start the automatic icemaking process.

14)When Comp starts, press and hold BC actuator paddle.

15)The 150-sec. shutdown sequence starts. 90 seconds after BC opens, Comp

de‑energizes, 60 seconds later, GM de‑energizes. If 5VDC is present at CB K4 connector pin #3 (GY wire) to #4 (V wire), and Comp or GM does not de-energize, replace CB.
