    Why is my Follett Horizon Elite HCD710AHS running but not making ice?
    • R
      Rebecca JohnsonAug 15, 2025
      If your Follett Ice Maker is running but not making ice, several components could be the cause. It might be due to a defective compressor, start relay, start capacitor, run capacitor, or main contactor. Replacing these parts may resolve the issue. Another potential cause is the lack of output from the PC board, in which case, you should replace the PC board.

    What to do if my Follett Horizon Elite HCD710AHS Ice Maker is not making ice and shows HI PRESSURE?
    • M
      Mrs. Kimberly Kirk DVMAug 18, 2025
      If your Follett Ice Maker is not making ice and showing a HI PRESSURE error, this could be due to several reasons: * High ambient temperatures (above 100°F or 38°C): Ensure the surrounding area is air-conditioned to below this temperature. * Poor ventilation or air recirculation: Reposition the ice machine to improve ventilation and prevent exhaust recirculation. * Clogged condenser (for air-cooled models): Clean the condenser grille. * Fan malfunction: Check for blockages, PC board issues, or a faulty fan motor. Remove any obstructions, replace the PC board if necessary, or replace the fan motor.

    What to do if Follett Ice Maker is not making ice and shows HI AMPS?
    • J
      John RiggsAug 22, 2025
      If your Follett Ice Maker is not making ice and displaying HI AMPS, it could be due to several reasons. Poor water quality might be causing ice to jam the auger; try cleaning the ice machine and setting the TDS switch to the High TDS setting. Also, check the drain for any blockages or slow drainage and clear or correct it. A damaged shuttle mechanism can also cause this issue; consider repairing or replacing it. Another possibility is an intermittent drive output from the PC board, which can freeze the evaporator, leading to a HI AMPS error, in that case, replace the PC board. Lastly, ensure the gearmotor is properly plugged in.

    Why is my Follett Horizon Elite HCD710AHS in TIME DELAY without a full bin?
    • M
      Mary CharlesAug 26, 2025
      If your Follett Ice Maker is in TIME DELAY without a full bin, it could be due to several reasons: * Ice jamming: This can occur if the transport tube is improperly installed, causing a false shuttle. Correct the transport tube routing. * Shuttle issues: If the shuttle is stuck in the up position, repair or replace the shuttle mechanism. * Thermostat problems: A damaged or improperly installed thermostat (open) can cause this. Replace or reposition the thermostat. * Transport tube coupling: If the transport tube has backed out of the coupling, correct the coupling installation.

    What to do if Follett Horizon Elite HCD710AHS Ice Maker is not making ice. Lo water?
    • B
      brownjakeAug 28, 2025
      If your Follett Ice Maker is not making ice and showing a Lo water issue, it could be due to several reasons: * Insufficient water supply: Restore the water supply and check the water filters. * Low water pressure: The ice machine should start once the water reaches the normal low level. * Defective water feed solenoid valve: If it's stuck in the closed position, replace the water feed solenoid valve.

    Why is there excessive water in the bin of my Follett Horizon Elite HCD710AHS?
    • C
      Christina CunninghamSep 1, 2025
      If your Follett Ice Maker is making ice but there is excessive water in the bin or coming into the bin from the transport tube, it could be due to a few reasons. The water sensors might have failed, causing the processor to incorrectly detect a lack of water. Try cleaning or replacing the water probe assembly and check the wiring connections. Another cause could be a blocked reservoir vent; in this case, clean or replace the vent tubes. Lastly, the water feed solenoid valve might be defective and stuck in the open position, requiring replacement.

    What causes a drain clog in a Follett Horizon Elite HCD710AHS that is making ice?
    • S
      Sarah MathewsSep 4, 2025
      If your Follett Ice Maker is making ice but has a drain clog, it could be due to improper flow in the drain system. Correct or clean the drain system to resolve this issue.

    What to do if Follett Horizon Elite HCD710AHS Ice Maker is not making ice. Drain clog?
    • L
      lerobertSep 7, 2025
      If your Follett Ice Maker is not making ice and showing a drain clog, it may be due to an internal water leak touching the chassis sensor. Identify and repair the leak, then clean and dry the chassis and sensors before restarting the machine.

    What does it mean when my Follett Ice Maker displays 'LOW WATER blinking and low bin'?
    • A
      Alicia MiddletonSep 12, 2025
      If your Follett Ice Maker shows 'LOW WATER blinking and low bin', this may indicate a refrigeration issue. Check the outdoor condensing unit to ensure it is functioning correctly.
