Possible Causes

Refrigerant leak in evaporator or condenser, Blocked capillary tube, Failing compressor, Severely dirty coils reducing heat exchange

How to Fix / Troubleshooting

Safety: Do not attempt to open the sealed refrigeration system yourself.

Steps:

  • Check basic operation: Ensure the unit is set to a low humidity (e.g., 40%) and that the compressor actually runs (you should hear a deeper humming sound and feel warm air from the exhaust).
  • Clean filters and coils: Remove and wash the air filter. Vacuum dust from the evaporator and condenser coils.
  • Check room conditions: Dehumidifiers are less effective at low temperatures. Ensure the room is within the specified operating range.
  • Inspect for icing: If the evaporator ices up quickly, there may be a refrigerant or airflow issue.
  • Professional service: If the compressor runs but the evaporator does not get uniformly cold and no water is collected after several hours, the unit likely has a refrigerant problem or weak compressor. Contact an authorized Olimpia Splendid service center for leak detection and repair or compressor replacement.
