Troubleshooting
In the event that your unit is not operating properly, check the following before calling for service assistance.
This may save you the cost of unnecessary service calls.
Symptom
Possible Cause of Problem
Unit not operating
Make certain that the unit is connected to a grounded outlet.
Make certain that temperature control knob is ON.
Check that circuit breaker is not tripped or fuse is not blown.
Unit runs continuously.
Make certain that there is no heavy frost accumulation. If there is, defrost
unit.
Look at condenser to see if there is a layer of dust or lint. Clean if required
with a dry brush or vacuum.
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 gasket if worn.
If you have temperature set too cold, this may cause unit to run continuous-
ly. Check optimum running temperature.
Is the ambient air over 43°C (109°F), or the units located close to heat
sources? If possible, move to a different location.
An unusually high frequency of door openings and closings can increase
operating load. Unit will stabilize as these are decreased.
Noise problems.
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.
Fan noise: normal airflow can cause this, not a problem.
