The alternative method of testing the icemaker unit is to use a 9-volt battery plus battery terminal and a multi
meter. The meter probes should be placed into the back of the icemaker 4 way socket onto the yellow and
blue wires. Check the continuity of the circuit to the tact switch in the ice mould tray. The switch should be
closed.
By applying a 9 volt DC supply across the white and red wires of the plug to the icemaker motor, it is
possible to drive the ice mould tray forward to a full twist of the tray and the tact switch will close again.
Note:
• 9-volt battery positive to the red wire to go forward.
• 9-volt battery positive to the white wire to go backwards.

10.1.4 Testing Water Valve
The water valves are located in the compressor unit compartment.
• Disconnect the refrigerator from the power supply.
• Remove the connector from the valve.
• Resistance of the water valves is 14 ± 5% (blue coils) and 10 ± 5% (red coils).
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.
