may save you the cost of unnecessary service calls.

22
Possible Cause of Problem
Make certain that the unit is connected to a grounded outlet.
Make certain that temperature control knob is not in OFF Position.
Check that circuit breaker is not tripped or fuse is not blown.
Make certain that there is no heavy frost accumulation. If there is, defrost
unit.
A leak around the door gasket will allow cold air to escape. This causes unit
to work harder than necessary to maintain cold temperatures. Re-seat or
replace the gasket if worn.
If you have temperature set too cold, this may cause unit to run
continuously. Check optimum running temperature.
An unusually high frequency of door openings and closings can increase
operating load. Unit will stabilize as these are decreased.
This can be caused by contents of unit being set too close and rattling
against each other. Rearrange contents as needed.
Hissing or gurgling noise is caused by refrigerating fluid circulating and is
normal.
Noise can result if unit is not level on floor. Check with level.
