How to Fix / Troubleshooting

Safety: Unplug before cleaning or sensor inspection.

  • Airflow: Clean the air filter and ensure vents are not blocked. Check for dust on coils.
  • Humidity setting: Lower the set humidity to 40–45% to force longer run times.
  • Sensor check: Inspect and, if necessary, replace the humidity sensor module if it is misreading.
  • Temperature sensors: Verify coil and ambient sensors are properly attached and not causing false overheat or defrost signals.
  • Control board: If sensors and airflow are good, the main control board may be defective.
