Problem Possible Cause Remedy
[1] a) Bin Control Thermostat 1. Set too cold. 1. Adjust warmer.
2. Defective. 2. Replace.
[2]
Abnormal noise.
a) Pump Motor 1. Bearings worn out. 1. Replace.
b) Fan Motor 1. Bearings worn out. 1. Replace.
2. Fan blade deformed. 2. Replace fan blade.
3. Fan blade does not move
freely.
3. Replace.
c) Compressor 1. Bearings worn out or
cylinder valve broken.
1. Replace.
2. Mounting pad out of
position.
2. Reinstall.
d) Refrigerant Lines 1. Rub or touch other lines or
surfaces.

water falls into bin.
1. Place in position.
b)
c) Pump Out Check
Valve
1. Dirty. 1. Clean.
[2] Cloudy or irregular
cubes.
a)
b) Spray Guide
1. Dirty. 1. Clean.
c) Water Quality 1. High hardness or contains
impurities.
1. Install a water softener or
filter.
See chart 1.[5] and check water supply line, water solenoid valve, water system,
pump motor, and controller board.
See chart 2.[1] and 2.[3], and check float switch, water solenoid valve, controller
board, spray tubes, water system, refrigerant charge, and expansion valve.

b)
[2]
Harvest cycle time is
long.
a)
See chart 1.[3] and check high pressure controller and water regulator.
See chart 2.[1] and check float switch, water solenoid valve and controller board.
See chart 2.[2] and check evaporator, water supply line, water filter system, water
solenoid valve, ambient and/or water temperature, line valve, thermistor, and
controller board.
Freeze cycle time is
long.
