Troubleshooting

Noise:
 If abnormal noise occurs, request service assistance.
 Operating sounds from compressor, condenser fan and interior fan are normal. Some
models are equipped with a drain pump.
 If sheet metal parts, front panels or panels in front of the compressor compartment are
making noise, these might be open. Close the panels. The front panel is equipped with
a catch, fitting into a locking system. The locking system could be locked
unintentionally, then the catch can be extracted with a tool.
Frosting inside compartment:
 Ambient humidity too high.
 The door is opened too often.
 The door is left open for too long.
 Damaged door gasket.
Poor cooling performance:
 Ambient temperature too high (above +43 °C).
 The door is opened too often and/or open for too long.
 The door is left open.
 Damaged door gasket.
 Cabinet temperature setting too high.
 Cabinet too packed with foods - air inlet/outlet blocked.
 Condenser mesh filter is clogged.
 Warm or hot foods inside.
 Defrost in progress. The cabinet temperature may rise temporarily during the defrost
cycle, but it will not affect the foods inside.
