Normal Ice Cube
Definition of a harvest problem; At the end of a 3.5
minute harvest cycle the slab of ice is still contacting
the evaporator. The slab of ice may or may not be
removable by hand.
Harvest problems can be split into two symptoms.
• Symptom 3 - Normal sheet of cubes at the end of
the harvest cycle. Ice is difficult to remove from the
evaporator by hand. Once removed the back of the
cubes are square and show no signs of melting.
This indicates a refrigeration problem. The source
of the problem could be in the freeze or harvest
cycle. Use the appropriate flow chart (in
Troubleshooting) to determine the cause of the
problem.
• Symptom 4 - Melted sheet of cubes at the end of
the harvest cycle. Ice can be removed rather easily
by hand. The back of the cubes are misshapen
and melted. This indicates something is preventing
the ice slab from releasing. Follow the appropriate
flow chart (in Troubleshooting) to determine the
cause of the problem. A manual cleaning
procedure must always be performed when this
problem is encountered.
