C. Bin Control Check
1. Thermostatic Bin Control Check: KM-1301SAH-E
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 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. Note that when the thermostatic bin control switch is open, the control board
red"POWEROK"LEDisoff.
1) Turn off the power supply.
2)Removethefrontpanel,thenmovethecontrolswitchtothe"OFF"position.
3) Clear any ice away from the thermostatic bin control bulb.
4) Remove the control box cover, then disconnect the thermostatic bin control wires from
the thermostatic bin control switch.
5) Hold your hand around the thermostatic bulb to warm it up.
6) Check for continuity across the thermostatic bin control switch. If closed, continue to
step 6. If open, adjust or replace the thermostatic bin control.
7) With the multimeter test leads still in place, hold ice on the thermostatic bin control 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.
2. Mechanical Bin Control Check and Cleaning: KM-1301SWH-E, KM-1301SRH-E
a) Mechanical Bin Control Check
To check the mechanical bin control switch, follow the steps below.
1) Turn off the power supply.
2)Removethefrontpanel,thenmovethecontrolswitchtothe"OFF"position.
3) Remove the control box cover, then clear any ice away from the mechanical bin control.
4) Check bin control cable and wire harness connections. See Fig. 1.
5) Disconnect the red connector from the control board RED K4 connector.
6) Check for continuity across the wires of the red connector. When the actuator paddle
is not engaged, the mechanical bin control switch is closed. If open, check that bin
control cable connector and the wire harness connector(s) are properly connected and
thattheactuatorpaddleisnotsticking.Cleanifnecessary.See"IV.C.2.b)Mechanical
