How to Fix / Troubleshooting
Safety: Unplug the unit. Do not attempt to open the sealed refrigeration system yourself.
- Check room conditions: Ensure the room is warm enough (typically above 15°C) and humidity is actually high. Dehumidifiers remove less water in cool rooms.
- Clean filters and coils: Remove and clean the air filter. Gently vacuum dust from the evaporator and condenser coils.
- Observe coil behavior: With the cover off (and extreme caution), briefly power the unit and observe the evaporator. It should become uniformly cool and may lightly frost. If only a small section gets cold or there is no cooling, refrigerant or compressor issues are likely.
Refrigerant diagnosis and recharging require specialized tools and certification. Contact an authorized Philips service center for sealed system repair or replacement.
