7.11 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.
Icemaker sensor located under insulated pad.
Sensor Insulation.
•
Disconnect the refrigerator from the power supply.
•
Remove the power module from the product.
•
Test the two white wires marked “0V” and “Ice Sensor” on the controller.
•
Testing of the sensor resistance should be in a known stable temperature, such as a glass of
water full of ice cubes.
7.12 Testing Icemaker Motor
ƒ Remove the icemaker from the freezer ceiling.
ƒ Disconnect the Molex connector.
ƒ Check the resistance between the White and Red wire on the connector. (Resistance
37.5
Ω
.)
If the icemaker sensor needs to be replaced, refer to Section 11.4.16.
7.13 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.
