If your Howe Ice Maker isn't producing the expected amount of ice, here are a few things to check:
* Ensure the Evaporator Temperature is correct by adjusting the refrigeration.
* Verify that the supply water temperature is within the recommended range of 45°F to 90°F. For temperatures below this range, contact Howe about a Low Temperature Mixing Valve.
* Confirm that the ambient temperature is between 50°F and 100°F. If you can't adjust the temperature, consider relocating the Ice Flaker. For temperatures below range, contact Howe about a Low Ambient Kit.

What causes a Howe Ice Maker water pump to stop running?
J
Jocelyn DanielSep 1, 2025
If the water pump on your Howe Ice Maker isn't running, here are a few potential reasons:
* A defective Control Module (CM) could be the cause. Verify 24 VAC is present across Term 1 (purple) and Term 3 (red) at the Control Module (CM). Also, check the voltage between Term 1 and Term 6 (blue). If there's no voltage, the Control Module (CM) may need to be replaced.
* Blown fuses might be the issue. Check for control voltage across the FU1 fuses and replace them if necessary.
* The Water Pump itself could be defective. Verify control voltage at terminals T1 Pump and T2 Pump in the Control Panel. If voltage is present, the Water Pump may need to be replaced.
* Loose wiring can also prevent the pump from running. Check all wire terminals and tighten them as necessary.

What causes a Howe Ice Maker Condensing Unit to be off on High Discharge Pressure Failure?
J
Jessica OrtizSep 3, 2025
If your Howe Ice Maker's Condensing Unit is off due to a High Discharge Pressure Failure, consider these possible causes:
* The system may have non-condensables, which should be removed.
* The system might be overcharged with refrigerant, so remove any excess.
* The fan may not be running. Check the Fan Cycling Control and adjust it as necessary.

What to do if my Howe Ice Maker's ice blade is frozen in place?
J
Jonathan SaundersSep 5, 2025
If the ice blade in your Howe Ice Maker is frozen in place, here's what you can check:
* The Motor Overload setting might be too high. Adjust the Motor Overload setting at the Control Module (CM).
* The ice might be freezing too thick or too hard. Adjust the refrigeration to the Ice Flaker.
* The Drive Motor may have stopped. See “Drive Motor will not start” above.
* The Flex Coupling could be broken. Check and replace the Flex Coupling as necessary.

What causes a Howe Rapid Freeze 4000-RL Condensing Unit to be off on Low Oil Pressure Failure?
C
Corey PowellSep 8, 2025
If your Howe Ice Maker's Condensing Unit is off due to a Low Oil Pressure Failure, here are potential causes:
* There may be a lack of refrigerant. Check for leaks and repair them, then add refrigerant.
* Refrigerant flood back could be occurring. Adjust the refrigeration to the Ice Flaker.
* Improper piping or traps may be present. Correct the piping.

Why is my Howe Rapid Freeze 4000-RL's condensing unit in low suction pressure pump down?
A
Abigail LopezSep 10, 2025
If the condensing unit in your Howe Ice Maker is experiencing a low suction pressure pump down, consider the following:
* There might be a lack of refrigerant. Check for leaks, repair them, and add refrigerant as needed.
* An insufficient water supply could be the issue. Replace the Water Filter and check for clogged tubes or valves.
* A refrigeration line blockage may be present. Check the filter drier, TXV, and EPR, replacing them if necessary.

What causes ice to not harvest at the bottom of the evaporator in a Howe Ice Maker?
C
Collin SheaSep 12, 2025
If ice isn't harvesting at the bottom of the evaporator in your Howe Ice Maker, here are a few possible reasons:
* The TXV might be underfeeding. Adjust the refrigeration to the Ice Flaker.
* The system may be short of refrigerant. Check for bubbles in the Sight Glass and charge the system as needed.
* The TXV sensing bulb might be improperly located. Relocate the bulb to the 4:30 clock position as originally set by the factory.

What causes ice to not harvest on one side of the evaporator in a Howe Ice Maker?
A
Andrea DyerSep 14, 2025
If ice isn't harvesting on one side or an angular section of the evaporator in your Howe Ice Maker, consider these potential causes:
* The Sleeve Bearings might be worn. Remove the Speed Reducer or Gear Motor and check for "play" in the Sleeve Bearings. Replace them if worn.
* The Ice Blade clearance could be too high. Adjust the Ice Blade clearance to the proper setting.

What causes ice to accumulate on the ribs of the bottom casting in a Howe Ice Maker?
T
Tiffany MillerSep 16, 2025
If ice is accumulating on the ribs of the bottom casting in your Howe Ice Maker, it could be due to a low ambient temperature. If the ambient temperature is below 50°F, relocate the Ice Flaker to a warmer area. You can also contact Howe about a Low Ambient Kit.

What to do if my Howe Ice Maker will not run?
C
Caroline DonaldsonNov 18, 2025
If your Howe Ice Maker doesn't start, here's what you can check:
* Ensure the Photo Eyes are securely connected. You can test them by placing a wire jumper between the "Blue" and "Black" terminals in the Control Panel. If it starts, the Photo Eyes might be faulty and need replacement.
* Try placing a wire jumper between terminals #5 (red) and #6 (red) at the Level Control Relay (LC1). If the Ice Maker starts, the Level Control Relay (LC1) may be defective and should be replaced.
* Check for 24 VAC voltage across Term 1 (purple) and Term 2 (yellow/orange) at the Control Module (CM). If there's no voltage, the Transformer (T1) might be defective and needs replacing.
* Place a wire jumper between Term 2 (yellow/orange) and Term 3 (red) at the Control Module (CM). If the Ice Maker sta...
