I learnt from a technician about how to repair AC remote control so I can help you out with it. The first step is to check and replace the batteries, as weak ones can cause the remote to stop working. If that doesn’t help, open the remote and clean the circuit board, and make sure you remove dust and moisture buildup. If the issue persists, check the IR LED with a phone camera or re-solder the loose connections.

We bought a new AC recently for our house but within a month, its remote stopped working. My father banged it against his hand, believing it was just a minor issue but he couldn’t make it work. I removed and inserted the batteries again and I understood that they were not inserted properly. If your remote is not working, there can be other reasons. So here are some suggestions on how to repair AC remote control.

How to Repair an AC Remote Control?

Your remote might not be working due to poor battery power or some other reason. Let me share some tips on how to repair your remote at home for minor issues:

  • Ensure the remote has fresh batteries and is properly inserted.

  • Clean battery contacts with a cotton swab and rubbing alcohol to make sure the remote works properly

  • If you feel there is a battery issue, remove the batteries, press any button for 5 seconds, and reinsert the batteries. 

  • Ensure buttons are not stuck or damaged. If they are, seek for a professional’s help

  • Check if the remote's infrared sensor is unobstructed and clean. If not, clean it with a dry cloth and recheck. 

  • If applicable, follow the AC unit manual to resynchronize the remote.

  • Look for physical damage in the remote. If you find any, replace the damaged components.

  • You can also look for updates or reset the remote's software.

But if problems persist, do not play with it. Seek help from the manufacturer or ask a professional to help you. And please don’t bang it. That doesn’t help much.
