Excessive Frost on evaporator
Shut down unit and thaw if frost is very thick. The unit may be used
in an abnormal manner. If the unit will continue to be used in this
manner the defrost length can be lengthened in the service menu
to prevent future issues. Extending this length may be detrimental
to the refrigerator temperature. During very long defrosts the
temperature may rise higher than desired.

Refrigerator too warm
Check the actual refrigerator temperature. If set to 38°F, the actual

operation. Recent door openings, product loading, or defrost
cycles will push the temperature higher for short time periods.
