Dehumidifier runs but does not collect water; humidity in the room remains high.

Safety first: Unplug the unit. The sealed system is pressurized; only certified technicians should open it.

• Check environment: Ensure room temperature is within the unit’s operating range. Dehumidifiers collect little water in very cold rooms.
• Inspect coils: Remove covers and inspect evaporator and condenser coils. Clean dust and lint with a soft brush and vacuum.
• Check for frost pattern: After reassembly, run the unit for 15–20 minutes. If only a small part of the evaporator frosts or stays warm, the system may be low on refrigerant.
• Look for oil stains: Oil residue on tubing joints often indicates a refrigerant leak.
• Call a professional: If a leak or low charge is suspected, contact an EPA‑certified technician. The compressor and sealed system require specialized tools and refrigerant handling.
