Safety: Unplug the dehumidifier before inspection. Refrigeration repairs should be performed by certified technicians.

Steps:

Check humidity and temperature: Ensure the room humidity is above the setpoint and the temperature is within the operating range (typically above 41°F/5°C).
Inspect coils: Remove the front or rear grille to view the evaporator coil. If it is heavily iced, turn off the unit and allow it to defrost completely. Clean the air filter and ensure good airflow.
Listen for compressor: When running, you should hear the compressor start (a deeper hum) in addition to the fan. If the fan runs but the compressor never starts, the relay or compressor may be faulty.
Check bucket and float: Ensure the bucket is seated properly and the float switch is not stuck in the full position.
Professional service: If coils are not cooling at all or refrigerant issues are suspected, contact a qualified technician. Compressor and sealed system repairs are not user‑serviceable.

Dehumidifier (Levoit) runs but does not collect water in the bucket.
