Page 4: The Icemaking Process
Follett icemakers used on top of an ice storage bin have a slightly different circuitry. A diagram for this type of icemaker is shown on page 9. The operational and diagnostic stages for these icemakers will be otherwise the same as stages 1 - 9 that follow. - Page 5 Normal operation – Stage 1 Power is supplied to L1 of the control board. The ice level control in the dispenser is closed and calling for ice, supplying signal voltage to the control board. The control board will now go through the start up sequence. Less than 30 seconds will elapse as the water sensor located in the float reservoir checks for water in the reservoir.
- Page 6 Normal operation – Stage 3 The gearmotor comes up to its normal running speed and the centrifugal switch located in the gearmotor opens, dropping out the start winding. As the compressor comes up to normal running speed, the compressor start relay contacts open, dropping out the start winding of the compressor.
- Page 7 Normal operation – Stage 5 The B-T LED will remain on for 20 minutes. The icemaker will not start while the B-T LED is on. To restart the icemaker for troubleshooting purposes, depress the reset button to clear the control board. INPUT POWER WATER...
- Page 8 Diagnostic sequence – Stage 7 The 20 Minute Error LED (20M) is on indicating that the control board has sensed an over-torque condition (above 3.5 AMPS on the gearmotor). The 20M LED will remain on for 20 minutes after an over-torque condition has occurred.
- Page 9 Diagnostic sequence – Stage 9 The second error (2ND) LED will come on if an over-torque condition occurs while the 60M LED is still lighted. The 2ND LED will indicate to the technician that two consecutive over-torque situations have occurred. The icemaker will be shut down at this time and will not restart unless the manual reset button is depressed.

Refrigerant replacement requirements 1. Non-contaminated refrigerant removed from any Follett refrigeration system can be recycled and returned to the same system after completing repairs. Recycled refrigerant must be stored in a clean, approved storage container. If additional refrigerant is required, virgin or reclaimed refrigerant that meets ARI standard 700-88 must be used. -
