MODELS WITH MECHANICAL BIN CONTROLCAUTIONDip Switch No. 7 must be set to the ON position. If No. 7 is set to the OFFposition, the machine will run continuously, causing a freeze-up condition.No adjustment is required. The Bin Control is factory-adjusted.[e] CHECKING THE CONTROLLER BOARD1) Visually check the sequence with the icemaker operating.2) Visually check the Controller Board by using the following procedures.(i)(ii)Adjust the Defrost Timer to minimum position.Disconnect the Thermistor from the Controller Board.Connect a 1.5 kΩ - 3.5 kΩ resistor to the Connector K3 (pins #1 and #2), and energizethe unit.After the 1 minute ± 5 second water supply cycle and the 2 minute ± 10 second defrostcycle, the unit should start the freeze cycle.After the above step (i), disconnect the Float Switch leads from the Controller Boardwithin the first 5 minutes of the freeze cycle.The unit should go into the defrost cycle after the first 5 minutes ± 20 seconds of thefreeze cycle.(iii) Reconnect the Float Switch Connector to the Controller Board. After the first 5minutes of the freeze cycle, disconnect the Float Switch leads from the ControllerBoard.At this point, the unit should start the defrost cycle.(iv)After Step (iii), de-energize the unit and confirm that the Defrost Timer is in theminimum position. Disconnect the resistor from the Controller Board, and energizethe unit.After the 1 minute water supply cycle, the defrost cycle starts.Reconnect a 1.5 kΩ - 3.5 kΩ resistor to the Connector K3 (pins #1 and #2) afterthe first 2 minutes of the defrost cycle.The unit should start the freeze cycle after 1 minute ± 5 seconds from the resistorconnection.25
