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 thermostatic bin
control switch opens and shuts down 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 bin control is factory set, and generally no adjustment is required. However,
adjustment may be needed in some conditions, particularly at higher altitude locations.
1) Turn off the power supply.
) 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
The oat switch is used to determine that there is sufcient water in the tank after the
1-minute ll cycle and after each harvest cycle. The oat switch is also used to determine
that the appropriate volume of water has been converted into ice before switching out of
the freeze cycle. No adjustment is required.
1. Float Switch Check
To check the oat switch, follow the steps below.
1) Turn off the power supply.
) Remove the front panel and move the control switch to the "OFF" position.
3) Remove the insulation panel, then remove the cap located on the front bottom part of
the ice dropping hole. Drain the water tank.
4) Replace the cap 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.. Float Switch Cleaning." After cleaning the oat switch, check it again. Replace if
necessary.
