  • Page 26: Service Diagnosis

    FM1500R 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 2 reset switches (circuit board and high pressure): depress and release each switch.
  • Page 27 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 (see page 38).
  • Page 28 FM1500R SERVICE DIAGNOSIS: Condition - No Ice Being Produced STATUS: GEARMOTOR OPERATES, COMPRESSOR DOES NOT A. Check the pump down control switch. 1. This pressure switch opens at 6-10 psig, and closes at 16-20 psig. If open check the low side pressure, if after running the machine the switch opens at a pressure higher than 10 psig, replace the switch.
  • Page 29 FM1500R SERVICE DIAGNOSIS: Condition - No Ice Being Produced STATUS: GEARMOTOR OPERATES, COMPRESSOR DOES NOT B. Check the compressor relay. The relay is on the circuit board, if it does not supply power to the liquid line valve coil, the low pressure control will not close, and the compressor will not run.
  • Page 30 FM1500R SERVICE DIAGNOSIS: Condition - Low Ice Production I. STATUS: EVERYTHING IS OPERATING A. Check the condenser for dirt. Clean as required. Check the head pressure. If the head pressure is very high: 1. Check for high air temperatures, or restrictive air flow. Correct as needed.
