PROBLEM POSSIBLE CAUSE SOLUTION
THE TEMPERATURE IS NOT
COLD ENOUGH The refrigerator has been used
improperly. The shelves must never be
covered with any type of plastic
or other material that will block
the circulation of cold air within
the refrigerator.
The refrigerator has been
overcharged with the
refrigerant gas. Check to see if condensation or
ice crystals have formed on the
suction line. If so, charge with
the correct amount of gas.
The refrigerant gas is leaking. Find the location where the gas
is leaking in order to seal it or
replace the defective
component. Change the drier.
Perform a good vacuum and
recharge the unit.
The evaporator and/or
condenser fans aren’t working. Check the electrical
connections and make sure
that the fan blade isn’t stuck.
Replace the fan motor if it
doesn’t work.
Low voltage. Use a voltage regulator if the
voltage is lower than 103 volts.
ELECTRICAL SHOCKS Wires or electrical components
are in direct contact with
metallic parts. Check for appropriate
insulation on the connections of
each electrical component.
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.
