2- With a Multi-meter having Direct Current Voltage Scale (Vdc), perform the Sensor VOLTAGE reading in
the Brown and Blue Wires (first to the left) the Connector connecting the Potency Module.
Note: For performing this operation, THERE IS NO NEED TO STRIP the wires; just insert the Testing Tips
directly to the connector metal contact.
3- Being the “Product Cool” (temperature below zero), the reading value shall be higher than 1.5 Vdc.
If the reading is LOWER than this value, then the Temperature Sensor replacement will be required. In this
case (in which the Temperature Sensor replacement is required), proceed in accordance to the instructions
given in item 6.7- Temperature Sensor Replacement.
IMPORTANT
Remember that the Refrigerators Alarm has a function, and this function must be accomplished
whenever a product failure occurs. Therefore, DO NOT CHANGE SENSORS UNNECESSARY.
