C. Bin Control Check

To check the thermostatic bin control, follow the steps below.

CAUTION

When the ambient temperature is below 45°F (7°C), 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 lled with ice. Setting in the prohibited range may

result in severe damage to the icemaker.

The thermostatic bin control is factory set, and generally no adjustment is required.

However, adjustment may be needed in some conditions, particularly at higher altitude

locations. Adjust it, if necessary, so that the icemaker stops automatically within

10seconds after ice contacts the bin control.

1) Turn off the power supply.

2) Remove the front panel, then remove the control box cover.

3) Disconnect the thermostatic bin control wires from the thermostatic bin control switch.

4) Clear any ice away from the thermostatic bulb, then hold your hand around the

thermostatic bulb to warm it up.

5) Check for continuity across the thermostatic bin control switch. If closed, continue to

step 6. If open, adjust or replace the thermostatic bin control.

6) With the multimeter test leads still in place, hold ice on the thermostatic bulb to lower

the temperature. Within 10 seconds, the thermostatic bin control switch should open (no

continuity). If it remains closed, adjust or replace the thermostatic bin control.

D. Float Switch Check and Cleaning

1. Float Switch Check

To check the oat switch, follow the steps below.

1) Turn off the power supply.

2) Remove the front panel. Move the control

switch to the "OFF" position, then remove

the insulation panel.

3) Remove the drain plug located on the lower

front part of the ice dropping hole. Allow the

water tank to drain. See Fig. 1.

4) Replace the drain plug in its correct

position. Be careful not to cross thread it.

5) Remove the control box cover.

6) Disconnect the black oat switch connector from the control board BLACK K5 connector.

7) Check for continuity across the oat switch leads. With the water tank empty, the oat

switch should be open. If open, continue to step 8. If closed, follow the steps in "IV.D.2.

Float Switch Cleaning." After cleaning the oat switch, check it again. Replace if

necessary.
