How to fix your RGB Fans LED Controller?

If your controller abruptly stops working or your lights start flickering, you might have to reset the controller and pair it back to the receiver unit. The controller once in a while un-sets itself from the receiver because of a free association, radio interference from an outside source, or a low battery in your remote. In case you are having this issue, reset and fix the controller by following this strategy:

  • First, make sure that the indicator light on the top of the remote is lighting up when you press a button. If it does not light up, your remote battery is likely the issue and you will need a new battery to replace it.
  • Disconnect your power source.
  • Unplug the dimming wire from both the power supply and LED strip light.
  • Remove the battery from the controller and then reinstall.
  • Plug the power supply and LED strip back into the receiver unit.
  • Reconnect the power supply to power.
  • With the remote, hold the ‘SPEED +’ and ‘SPEED -‘ buttons down simultaneously for 3 seconds. The indicator light should blink once to show you have done this correctly.
  • The remote and receiver should now be paired and the light strip should be controlled by the remote.
