Page 19: Service Diagnosis
FM1500 SERVICE DIAGNOSIS: Condition - No Ice Being Produced STATUS: NOTHING OPERATES A. Check: Voltage to the unit, restore it if there is none. Compare to the nameplate. B. Check: The master switch, switch ON if off. C. Check: The 3 reset switches, (circuit board, high and low pressure): depress and release each switch. - Page 20 If the bin empty light is still OFF, check the circuit board. 1. Unplug "opto trans" and "LED" connectors from the circuit board. 2. Plug "opto trans" and "LED" connectors from the Scotsman Electronic Control Testor Model NM1 into the circiut board.
