How to Fix / Troubleshooting

Safety first: Unplug the unit before accessing the compressor compartment.

  • 1. Check leveling:
    • Ensure the dehumidifier is level and on a solid surface.
  • 2. Inspect mounts:
    • Remove the rear panel and inspect compressor mounting bolts and rubber grommets.
    • Tighten loose bolts and replace damaged grommets.
  • 3. Secure tubing:
    • Look for copper refrigerant lines touching the cabinet.
    • Gently bend or pad lines so they do not contact metal surfaces.
  • 4. Evaluate noise:
    • If the noise is extremely loud or accompanied by poor performance, the compressor may be failing and should be evaluated by a technician.
