are the reasons behind “refrigerator making noise” problem?
Noise from refrigerator
is not uncommon. Routine operation of your refrigerator will cause some sound.
Some of the sounds that you commonly hear from your refrigerator are: clicking
sound which is heard when the defrost timer switches on-off, knocking sound is
heard during the circulation of refrigerant and humming noise is heard when the
ice maker fills with water. But when your refrigerator makes sounds that are
not normal, you may require a technician for diagnosis.
Common reasons behind refrigerator making noise
- Fault in the condenser fan motor or blade: If your fridge is making loud noise, then condenser fan can be
defective. In frost free refrigerators a condenser fan is located near the
compressor at the bottom of the fridge. A condenser fan circulates air over the
condenser coil to remove heat produced in the process of compression of
refrigerant. There are chances that some debris or obstruction might be
preventing the condenser fan from moving freely or the fan blades might have
worn out or the fan motor is at fault and needs to be replaced.
- Faulty evaporator fan motor or blade: If your refrigerator is making loud noise that appears to be coming
from the freezer section, then the evaporator fan might be at fault. An
evaporator fan is located in the freezer section which circulates cool air in
the food section of your fridge. There are chances that the evaporator fan
blades of refrigerator are worn out or the fan blades have become loose, or the
fan motor shaft does not turn freely. Sometimes due to defrost problem of
refrigerator ice gets deposited on the fan blade, preventing the blades from
moving freely. These obstructions in the free movement of evaporator fan,
faulty motor, damaged blades etc. result is refrigerator making noise problem.
- Worn-out compressor: The
compressors of refrigerator are little loud and noisy. But if the noise from
fridge become louder than normal, then the compressor might be at fault. If the
noise from refrigerator continues to worsen, it is an indication that the
compressor is likely to fail in the near future. A faulty compressor is the
most probable reason behind refrigeration making noise problem.
- Clogging in the inter water valve: If your refrigerator makes noise, particularly when the ice maker
is filling, the inlet water valve might be at fault. Noise from fridge can be
caused by the obstruction in the inlet valve from mineral and scale deposit. In
such case when noise from refrigerator is due to obstruction in valve, it needs
to be replaced.
The above are
some common reasons behind refrigerator making noise problem but there can be
other reasons as well.
What is included in the service?
