How to Fix / Troubleshooting

Safety: Unplug the unit before cleaning or opening panels.

  • Check ambient temperature: Ensure the room is not excessively hot (above ~95°F / 35°C). Move the unit to a cooler area if needed.
  • Improve ventilation: Provide at least 8–12 inches of clearance around the unit. Do not operate it inside a closet or enclosed space.
  • Clean filter and vents: Remove and clean the air filter. Vacuum dust from intake and exhaust grilles.
  • Sensor check: If HI appears in a normal-temperature room, inspect the ambient temperature sensor and wiring. Replace the sensor if it is damaged or reading incorrectly.
