PROBLEM POSSIBLE CAUSE SOLUTION
NOISE The refrigerator is not properly
leveled. Check if the noise goes away
after you level the refrigerator.
The condenser is not fastened
correctly. Copper tubings are in
contact with metal. While the compressor is
working, check to see if metal
parts are in contact with one
another and/or if the screws
that fasten the condenser are
tightened.
The evaporator and/or
condenser fans are loose. Check if the fans are securely
fastened. Also, check if the fan
blades are loose, broken or
crooked. If so, change the
faulty blade.
Compressor has an internal
noise. If the noise persists after all
other measures have been
taken, it may be originating
from the compressor.
EXTREME CONDENSATION
INSIDE THE REFRIGERATOR Thermostat knob is set at a
very cold position. Set the thermostat knob to a
warmer position and check if
the compressor stops
according to the thermostat’s
operating range.
The outside environment’s
relative humidity is very high
(over 75%). This type of occurrence is
caused by local climatic
conditions and not by the
refrigerated unit.
The refrigerator door won’t shut
completely. Check the door and/or the
magnetic gasket. Adjust the
door hinges if needed; replace
the gasket if broken.
The refrigerator has been
placed at an inadequate
location. The unit must not be near
sources that produce too much
heat.
NO ILLUMINATION The light switch is in “off”
position. Press the light switch to the
“on” position.
False contact on the light
switch, the fluorescent tube, or
the ballast. Inspect all connections.
Light switch, ballast and/or
fluorescent tube are damaged. Replace the damaged
component.
