D. Bin Control Check

When the actuator paddle is not engaged, BC is closed and the appliance produces ice. S1 dip switch 7 must be in the "OFF" position. When ice fills the chute and engages the actuator paddle, BC opens and CB shuts down the appliance within 10 seconds.

NOTICE! Do not place S1 dip switch 7 in the "ON" position. For details, see "III.C.1. Default Dip Switch Settings."

1)Remove the front and top panels.

2)Remove the storage bin cover. If necessary, dispense ice or remove ice manually so that the BC actuator paddle is not engaged.

IMPORTANT! Appliance will not start unless the safety switch is engaged. WARNING! Keep hands, hair, and loose clothing clear of the agitator rotating inside of the storage bin.

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 BC connector from the back of the control box.

7)Check for continuity across BC proximity switch. 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. If BC actuator is engaged and BC proximity switch is open, replace BC proximity switch.

9)Disengage BC actuator paddle.

10)Reconnect BC connector. Remove the control box cover.

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

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

16)Comp and GM should deenergize within 10 seconds. Diagnosis: If not, and BC is found open and the appliance continues to run, replace CB.

17)Move the power switch to the "OFF" position and turn off the power supply.

18)Move the power switch to the "ON" position.

19)Replace the storage bin cover, control box cover, top panel, and front panel in their correct positions.

20)Turn on the power supply to start the automatic icemaking process.
