TESTING ICEMAKER SENSOR

The icemaker sensor is located on the bottom of the ice cube tray. The testing is carried out at the power
module.
Disconnect the refrigerator from the power supply.
Remove the power module from the product.
Test two white wires marked "0V" and "Ice Sensor" on the controller.
Testing of the sensor should be in a known stable temperature, such as a glass of water full of ice cubes.
7.17

TESTING ICEMAKER MOTOR

Remove the icemaker from the freezer ceiling.
Disconnect the Molex connector.
Check the resistance between the White and Red wire on the connector. (Resistance 37.5Ω.)
7.18

TESTING WATER VALVE

The water valves are located in the unit compartment.
Disconnect the refrigerator from the power supply.
Remove the connector from the valve.
Resistance of the water valves is 14 Ω± 5%.
When testing for voltage at the ice or water valve:
Disconnect the refrigerator from the power supply.
Remove the connector from the water valve.
Place the meter probes into the connector of the valve that is faulty (ice valve or water dispenser valve).
Reconnect the refrigerator to the power supply.
Place a glass into the dispenser to operate the valve (for water dispenser valve only).
Place the product into a forced harvest (for icemaker only).
The voltage at the connector (once disconnected from the valve) should be 12 volts DC. Care should be taken
not to damage the connector or wiring.

TESTING THE FLOW METER (Products before January 2009)
The flow meter cannot be tested electrically. If a fault occurs where the flow meter is suspected to be faulty,
the Flow Meter Calibration procedure (refer to Section 0 Flow Meter Calibration) is to be followed, and if after
the procedure has been followed the fault still exists, replace the flow meter.
Icemaker sensor located under insulated pad.
Sensor Insulation.
