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. Refer to sensor resistance table (refer to Section 4.22).
10.1.3 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 marked
Icemaker
from the module.
•
Check the resistance of the motor between pins 5 and 6 – resistance should be 35
Ω
+/- 5%.
•
Check the tact switch continuity between pins 4 and 7 – the switch should be closed.
NOTE:
To identify pin numbering, Pins 10 and 11 are White wires
If the icemaker sensor needs to be replaced, refer to Section 11.1.4.
Pins 10 & 11
