Non-Failure Analysis; Trouble Shooting - Whirlpool WF179 Operating Instructions Manual

Non-failure analysis

• Both sides of the refrigerator has a condenser, it is a normal phenomenon to be heated during operation.
• The temperature is high inside the refrigerator during the first time operation, cooling time will be longer.
• Due to the high flow rate of refrigerant in the capillary within the refrigeration system, water running sounds may
occur sometimes.
• When the humidity is high, it is a normal phenomenon for dew appearing on the refrigerator surface and
particularly near the door sealing.
• Buzz: Buzz will be generated by running compressor specially when starting up or shutting down.
• Clatter: The solenoid valve or electric switch valve will clatter which is a normal phenomenon and does not
affect the operation.
• The refrigerating chamber will periodically frost and defrost (water drops will be generated on the backside of
the refrigerating chamber when defrosting) which are normal.
• When closing one of the doors, the another one may be opened because of the wind pressure, which are normal.
