Possible Causes

Low refrigerant charge due to leak, Failed compressor, Faulty compressor start relay or capacitor, Severely iced evaporator coil preventing drainage

How to Fix / Troubleshooting

Safety first: Unplug the dehumidifier before removing panels. Do not attempt sealed system repairs yourself.

  • Step 1 – Check ambient conditions: Ensure room temperature is above 65°F (18°C). Dehumidifiers are less effective in cooler rooms.
  • Step 2 – Inspect coils: Remove the cover and observe the evaporator coil after 10–15 minutes of operation. It should be cool with some condensation, not completely dry or heavily iced.
  • Step 3 – Listen for compressor: The compressor should run with a steady hum. If only the fan runs, the compressor may not be starting.
  • Step 4 – Check start components (advanced): Inspect the compressor start relay and capacitor for burn marks or swelling. Replace with correct AIRCARE parts if defective.
  • Step 5 – Evaluate for sealed system issues: If the compressor runs but the coil never gets cold, or only a small section gets cold, the unit may have a refrigerant leak or internal restriction.

Sealed system repairs require specialized tools and certification. In many cases, replacement of the dehumidifier is more economical than repairing a leak.
