Testing Icemaker Motor
Testing of the icemaker motor is carried out at the power module.
Note: Before any testing is carried out ensure the product has an ice bin in place and the icemaker arm
is in the down position.
Procedure:
•
Disconnect the refrigerator from the power supply.
•
Remove the power module to expose connectors.
•
Remove the connector from the Icemaker PCB.
•
Check the resistance of the motor between pins 5 & 6 – Resistance should be 35
Ω
+/- 5%.
•
Check the tact switch continuity between pins 4 & 7 – The switch should be closed.
Note: To identify pin numbering, Pin 10 and 11 are White wires
4.8
Water Valve Testing
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 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 of 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.
