How to fix it

  1. Press the Alarm Reset/HI button to silence the alarm.
  2. Check that all doors are fully closed and gaskets seal.
  3. Allow up to 24 hours for temperature to recover with normal load.
  4. If HI returns, verify evaporator fan is running and coil is not iced over.
  5. Check condenser coil is clean.
  6. If temperature does not recover, diagnose cooling system (compressor, sealed system, sensors).
