3.60 seconds after the "GM" LED comes on, the "COMP" LED comes on, and the compressor and fan motor start. If the "COMP" LED does not come on 60 seconds after the gear motor starts, check that the gear motor protect relay contacts (connector K2 terminals 1 and 2) have closed. If the "COMP" LED is on and the compressor and fan motor did not start, check for 115/120V at X2 (LBU) and X2 (BR) on the control board to neutral. If the "COMP" LED is on and there is voltage at X2 (BR) to neutral and no voltage at X2 (LBU) to neutral, the control board is bad and should be replaced. See wiring diagram "III.C.3. Freeze Cycle" for further details.

c)Dispensing Components DCM-500BAH, DCM-500BWH

1.Ice Dispense "Continuous": Pressing the ice dispense switch closes terminals 6 and 5 at the K4 connector. The "DM" LED comes on and the dispensing motor energizes. If the "DM" LED does not turn on, check continuity through the ice dispense switch and the dispense mode switch. If the LED is on and the dispensing motor does not start, check for 115/120V at connector K2 terminals 3 and 6 to a neutral. With voltage at terminal 3 and not at terminal 6, the control board is bad and should be replaced. Note: The agitating motor will operate .6 seconds every 12 seconds of accumulative

dispense time. See "III.D.1. Continuous Dispense."

2.Ice Dispense "Portion": Pressing the ice dispense switch closes terminals 6 and 7 at the K4 connector. The "DM" LED comes on and the dispinsing motor energizes. If the "DM" LED does not turn on, check continuity through the ice dispense switch and the dispense mode switch. If the LED is on and the dispensing motor does not start, check for 115V at connector K2 terminals 3 and 6 to a neutral. With voltage at terminal 3 and not at terminal 6, the control board is bad and should be replaced.

Note: The agitating motor will operate .6 seconds every 12 seconds of accumulative dispense time. See "III.D.2. Portion Dipsense."
