Icemaker (Continued)
Repair circuit and connections or replace door switch as needed. When there is power,
recheck icemaker operation. If there is still not ice, check for water problems next.
WATER PROBLEMS
CAUTION: Do not use a Reverse Osmosis Water Filtration System. It reduces the
water pressure below 20 psi and the icemaker will not fill. Use of a Reverse Osmosis
system will void the warranty.
Poor water quality can cause icemaker to fail or produce unacceptable cubes. Install a
water filter to eliminate bad taste, odor, and visible contaminates. Mineral content or
sand can restrict screen in water fill valve or particles of sand can keep valve from seating
properly. If water valve does not operate properly, the following could occur:
•
No ice production
•
Small or hollow ice cubes
•
Flooding of ice container
Mineral content can cause lime build up in the mold, wicking of water over the mold and
poor cube release. Mineral content can also restrict saddle valves.
WATER SUPPLY
1. Water supply is turned OFF. Turn water supply line ON.
2. Water pressure too low (below 20 psi). Check pressure at source. If OK, look
for obstructions or restrictions as follows.
3. Saddle valve not fully open. Open valve fully.
4. Saddle valve fully opened but still restricted. Quick fix: Fully close and
reopen to dislodge sediment. If necessary, remove valve and enlarge pierced
hole to 3/16” diameter with a drill and reinstall saddle valve.
5. Water line to unit pinched/kinked/clogged. Repair water line.
6. Ice in inlet tube blocking water flow. Remove ice from tube.
7. Water pressure too high (above 120 psi). Install pressure regulator.
WATER FILL LEVEL
NOTE: The water fill level adjustment screw is located under the motor cover. See
Figures 2 and 3. the icemaker mounting brackets gave built-in differences so that the
motor end will be slightly below (1/2º) the water fill end. See Figure 5. The purpose is
to help the water fill all the cavities with slight excess at the motor end where the
thermostat is located. This insures the motor end is the last to reach 15º F. This prevents
early cycling which results in hollow ice cubes.
