TROUBLESHOOTING GUIDE

PROBLEM

POSSIBLE CAUSE

CORRECTION

Ice is not clear.

1. Low water level in reservoir.

Make sure that the reservoir drain plug is installed properly.

Check the water line to the unit to make sure there are no

restrictions or kinks in the line. Check all filters to make sure

they are not restricted or plugged.

2. Softened water supply.

Make certain that the water line is not connected to the

water softener.

3. Room temperature is too cold.

Move the unit to an area where room temperature is above

55 degrees F.

Low ice production. Unit

is running, has run over

a 48 hour period, and

there is little ice in the

bin.

1. Low water level in reservoir.

Make sure that the reservoir drain plug is installed properly.

2. Distributor tube is restricted.

Check the water line to the unit to make sure there are no

restrictions or kinks in the line. Check all filters to make sure

they are not restricted or plugged.

3. Build-up of deposits on evaporator

plate.

See “CLEANING YOUR ICE MACHINE” section for cleaning the

unit for proper operation.

4. Inadequate drain system.

Restriction in drain lines will cause ice in the bin to melt. If

using a gravity drain, make certain there are no kinks or re-

strictions in the drain lines. If using a drain pump, check the

inlet screen, discharge line, and vent line for any build-up or

restrictions.

5. Condenser fan air flow is restricted.

Make certain the grille in the front of the unit is free and

open for proper air circulation.

Unit continues to run

and produce ice.

1. Ice bin is not full.

The unit will automatically shut down when ice reaches the

sensing tube.

2. Ice bin is full.

The unit will automatically shut down when ice reaches the

sensing tube and has completed the harvest of the ice slab.

3. Room temperature is too warm.

Move the unit to an area where room temperature is below

90 degrees F.

4. Ice machine is not level.

Use a level to check the unit for level from side to side and

front to rear.

Grid-cutter is not cutting

the ice slab.

1. The selector switch is not in the “ON”

position.

Set the rocker switch on the grille of the ice machine to the

“ON” position.

2. The grid-cutter is not plugged into the

receptacle.

Remove the escutcheon panel and plug the grid-cutter into

the receptacle on the side of the cabinet liner.

3. Time to cut through the slab.

It can take up to 35 minutes to cut through a harvested ice

slab. This is normal operation.
