19.7: Trouble Shooting
19.7.1 Ice Machine Operation:
19.7.1.1 Ice Machine does not operate:
1. Is the machine power cord plugged in?
2. Is the electronic control showing the “ICE” position?
3. Is a fuse blown or breaker tripped?
4. Is the room temperature cooler than normal?
a. Minimum room temperature for an ice machine to operate efficiently is
55°F (13°C). The bin sensor may sense a full bin condition and prevent the
ice machine from going into a production mode.
5. Does the appliance have a drain pump?
a. The drain pump may be removing water from the system.
19.7.1.2 Ice Machine is noisy:
1. Can water be heard circulating in the ice machine?
2. Customer education is a possibility: The process of making ice involves a
refrigeration cycle, water circulation and a combination of solenoids, valves, and
motors. It is not a quiet procedure.
19.7.2 Ice Production:
19.7.2.1 Little or no ice:
1. Is the control set to the “Ice” position?
2. Is the supply water present at the fill valve?
3. How long has the ice machine been running?
a. A typical production cycle can take up to 1 ½ hours. Start time is typically
longer at the initial start-up. After 24 hours, the bin should be near
capacity without any consumption.
4. Is the water reservoir drain plug in place?
5. Is water flowing out of the water distribution tube?
6. Is the condenser fan operating without restrictions in the air flow?
7. Is the room or water temperature too warm?
a. Maximum ice capacity is achieved in an ambient less than 90°F (32°C). It
is also recommended that the ice machine not be placed in direct
sunlight, next to a stove, range, space heater, hot air registers, hot water
radiators, or any other type of direct heating source. Excessive heat will
deter ice production and storage.
b. It is important to realize that the ice bin is not a refrigerated
compartment. Cooling for ice storage is essentially created by the ice
itself.
8. Is there scale built up in the ice machine?
a. Initiate a clean cycle with a recommended nickel-free cleaner.
