Problem
Possible Cause
Possible Solution
Drive Motor will not run
or
Ice Flaker in Overload Condition
1.
Defective Control Module (CM).
1.
Verify 24 VAC present across Term 1 (purple) and Term 3 (red) at Control Module
(CM). Check voltage between Term 1 and Term 6 (blue). If no voltage present,
Control Module (CM) may be defective and need to be replaced.
2.
Defective Drive Motor.
2.
Verify control voltage at Drive Motor wire leads. If voltage is present, Drive Motor
may be defective and need to be replaced.
3.
Defective Motor Relay (R1).
3.
Place two wire jumpers between terminals #9 (black) and #11 (blue/brown) and
terminals #1 (blue/brown) and #3 (black) at Motor Relay (R1). If Drive Motor stars,
Motor Relay (R1) may be defective and need to be replaced.
4.
Sleeve Bearings are seized.
4.
Remove the Gear Motor from the Mounting Hub or the Speed Reducer from Top
Casting and try to push the Ice Blade by hand. If the Ice Blade will not move, the
Sleeve Bearings may be seized and need to be replaced.
5.
Gear Motor or Speed Reducer is seized.
5.
Remove Gear Motor or Speed Reducer and bring voltage to the motor. If the
output shaft cannot turn while not attached to the Ice Flaker, it may be seized and
need to be replaced.
6.
Motor Overload setting is too low.
6.
Raise the Motor Overload setting at the Control Module (CM). Verify the
amperage draw is in correspondence with the nameplate.
7.
Loose wiring.
7.
Check all wire terminals and tighten as necessary.
Water Pump will not run
1.
Defective Control Module (CM).
1.
Verify 24 VAC present across Term 1 (purple) and Term 3 (red) at Control Module
(CM). Check voltage between Term 1 and Term 6 (blue). If no voltage present,
Control Module (CM) may be defective and need to be replaced.
2.
Defective Water Pump.
2.
Verify control voltage at Water Pump wire leads. If voltage is present, Water Pump
may be defective and need to be replaced.
3.
Defective Motor Relay (R1).
3.
Place two wire jumpers between terminals #9 (black) and #11 (blue/brown) and
terminals #1 (blue/brown) and #3 (black) at Motor Relay (R1). If Water Pump
starts, Motor Relay (R1) may be defective and need to be replaced.
4.
Loose wiring.
4.
Check all wire terminals and tighten as necessary.
Ice does not harvest
at the bottom of Evaporator
1.
System is short of refrigerant.
1.
Check for bubbles in the Sight Glass. If present, charge system as needed.
2.
Superheat setting too high.
2.
Adjust Kelvin II controller to factory settings. (see pgs. 31-32)
Ice does not harvest on one side
or angular section of Evaporator
1.
Sleeve Bearings are worn.
1.
Remove Speed Reducer or Gear Motor and check for “play” in Sleeve Bearings.
Replace if worn.
2.
Ice Blade clearance is too high.
2.
Adjust Ice Blade clearance to proper setting.
Ice accumulates on the ribs of
Bottom Casting
1.
Ambient Temperature is too low.
1.
If ambient temperature is below 50°F, relocate Ice Flaker to a warmer area.
