SYMPTOM #3 HARVEST PROBLEMS

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 categorizes.

• 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 on the evaporator

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.

• 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.
