  • Page 15: Service

    Service Ice machine Operation (all models) Follett’s ice machine consists of four distinct functional systems: § Harvesting system § Water system § Electrical control system § Refrigeration system These four systems work together to accomplish the production and harvesting of ice . A problem in any one of these systems will result in improper operation of the entire ice production cycle .

  • Page 16: Water System

    Water system The water level in the evaporator is controlled by a fill solenoid (Fig 13) and level detecting sensors . Water sensing rods (Fig. 14) extend down into the reservoir at the end of the evaporator assembly . The system works via electrical conductivity as follows: One of the longest probes is a common .

  • Page 20: Ice Machine Operational And Diagnostic Sequences

    Ice machine operational and diagnostic sequences The wiring diagrams that follow illustrate the circuitry of Follett ice machines used with 25/50 series ice dispensers . Both normal operation (stages 1—8) and non-normal diagnostic sequences showing torque-out for use in troubleshooting are shown .
  • Page 21 Normal operation – Stage 2 When continuity is seen between B and C, the water valve de-energizes, the AUGER output (P4) comes on along with the MAKING ICE LED . The auger gearmotor’s start windings are energized through a current style start relay that is pulled in by the initial high current draw of the gearmotor .
  • Page 22 Normal operation – Stage 4 One second (1 s) after the fan comes on, the COMPRESSOR output comes on . The compressor circuit uses both run and start capacitors along with a potential start relay . The start capacitor in energized through the normally closed contacts of the start relay .
  • Page 23 Normal operation – Stage 6 Once the bin thermostat control opens, the LOW BIN LED goes out . The compressor and gear motor outputs turn off, the MAKING ICE LED goes out and the TIME DELAY LED comes on . . T.O.L.
  • Page 24 Normal operation – Stage 8 When the dwell time of 20 minutes has expired, the TIME DELAY LED goes off . If 5 seconds of ice has been dispensed and the SLEEP CYCLE LED (Symphony Plus only) is off, the ice machine will go through the normal start-up sequence when the bin level control signals the control board for ice .

  • Page 25: Diagnostic Stages

    Self-flushing (when enabled) At the completion of the 20 minute time delay, the machine checks for a cumulative one hour of ice making time since the last off-cycle flush . If the cumulative ice making time exceeds one hour, the machine will energize the drain valve P19 for 60 seconds to drain the evaporator .
  • Page 26 High gearmotor amps – Stage 2 If the restart is successful the board will continue to monitor the current draw on P4 for 60 minutes looking for a second high amps (above 3A) occurrence . If the ice machine runs without problems for 60 minutes and no additional torque errors occur, the ice machine will continue normal operation .
  • Page 27 Loss of water During operation, the water level cycles between the normal low (D) and normal high (C) water probes - the fill valve (P21) cycling on and off . If continuity is not detected between the common probe (B) and normal low (D) within 10 seconds, the LOW WATER and TIME DELAY LEDs will come on and the machine will shut down for the one hour time delay period .
  • Page 28 High refrigerant pressure Should the refrigeration pressure rise above 425 psi, the high pressure switch contacts will open . The board sees the open circuit and the HIGH PRESSURE and TIME DELAY LEDs will come on, the machine shuts down . After the one hour time delay, the machine will attempt to restart .
