Air Conditioners - Remote Control Operation and Troubleshooting

Built-in and portable air conditioners, as well as some window air conditioners have remote controls for easy control of the air conditioner. Remote controls are universal (across the same model), so one remote can operate multiple units in the home. When the air conditioner is turned on, it will automatically start in the setting last used.
To ensure proper operation, be sure to...
  • Aim the remote control directly at the signal receiver on the air conditioner. 
  • Use the remote control within range of the signal (about 21 feet).
  • Check that nothing is between the air conditioner and the remote control that could block the signal, like furniture.
  • Use batteries that are fresh and installed correctly. 
Caution: Since one remote can operate multiple models, if you have two units installed in the same room, the remote may control them both at the same time if they are both within range of the remote. 
To replace the batteries (for most models):
  1. Remove the battery cover by sliding it according to the arrow direction.
  2. Insert new batteries, making sure that the (+) and (–) of battery are installed correctly.
    • Use 2 "AAA" alkaline batteries (most models).
    • We recommend that you open the battery cover and confirm your battery type before buying new batteries. 
    • Do not use rechargeable batteries.
    • Do not mix old and new batteries. 
  3. Reattach the cover by sliding it back into position.
