Non-Failure Phenomena
Surface Condensation
Condensation on the exterior surfaces (especially door seals and glass) is normal in high temperature and humidity environments due to the low internal temperature. Wipe with a soft cloth. It will disappear as ambient conditions improve.
To reduce condensation:
- Wipe surfaces regularly with a soft cloth, especially during humid seasons.
- Ensure the unit is placed in a well-ventilated area.
Operating Sounds
A slight "buzzing" sound from the compressor and "running water" sounds from refrigerant flow are normal operating noises.
Vibration and noise can occur if the unit is not placed smoothly.
