5) Freeze Timer

CAUTION

Adjust to proper specification, or the unit may not operate correctly.

The freeze timer is factory adjusted and no adjustment is required. This setting determines the maximum allowed freeze time to prevent possible freeze-up issues.

6) Bin Control

CAUTION

When the ambient temperature is below 45°F, the bin control thermostat operates to stop the icemaker even if the ice storage bin is empty. When the thermostat is set in the prohibited range, the icemaker operates continuously even if the ice storage bin is filled with ice. Setting in the prohibited range might cause severe damage to the icemaker resulting in failure.

No adjustment is required under normal use, as the bin control is factory-adjusted. Adjust it, if necessary, so that the icemaker stops automatically within 10 seconds after ice contacts the bin control thermostat bulb.

[e] Checking the Controller Board

1)Visually check the sequence with the icemaker operating.

2)Visually check the controller board by using the following procedures:

(i)Adjust the defrost timer to minimum position.

Disconnect the thermistor from the controller board.

Connect a 1.5 k- 3.5 kresistor to the connector K3 (pins #1 and #2), and energize the unit.

After the 1 minute ± 5 second water supply cycle and the 2 minute ± 10 second defrost cycle, the unit should start the freeze cycle.
