Troubleshooting By Symptom
The troubleshooting procedures follow flow charts.
There are four symptoms, the symptom that you are
experiencing will determine which flow chart to use.
The flow chart asks yes and no questions to determine
the problem. The flow chart will direct you to a
procedure to correct the problem. Traditional remote
and self contained models use seperate charts.
SYMPTOM #1
Ice Machine Stops Running
Toggle Switch is in the ICE position
or
Has a History of Shutting Down
• Refer to Ice Machine Stops Running Flow Chart
(page 90)
SYMPTOM #2
Ice Machine has a Long Freeze Cycle.
Ice Formation is Thick
or
Thin Ice Fill on Top or Bottom of Evaporator
or
Low Production
Safety Limit #1 (possible)
• Refer to Freeze Cycle Refrigeration System
Operational Analysis Table
(page 105)
SYMPTOM #3
Ice Machine Will Not Harvest - Freeze Cycle is
Normal and Ice Cubes are Not Melted After Harvest
Safety Limit #2 (possible)
• Refer to Refrigeration Harvest Flow Chart
(page 127)
Symptom #4
Ice Machine Will Not Harvest - Freeze Cycle is
Normal and Ice Cubes are Melted After Harvest
• Refer to Ice Meltout Flow Chart
(page 131)
