LED lightbulbs are manufactured using digital circuitry that can emit electromagnetic noise in the range of 30MHz to 1000MHz, while garage door openers operate on frequencies between 310MHz and 390MHz.

If your garage door opener is having range problems or only works intermittently, try removing any LED lightbulbs that are located in or near the garage, and then test your garage door opener.

The interference could also originate from nearby LED lights and those of your neighbors. In this case, you can try finding the source by using a portable radio. Set the radio to a low AM dial and make sure that there’s no static or sounds coming out of it. Start scanning the desired area and point the device towards potential sources. Once the radio starts to make noises such as static sound or buzzing, you’ve found it.

What LED Lights Should You Use to Prevent Interference?

Use LED lights that work on 50-60Hz and that are in compliance with the FCC regulations. Look for the FCC mark on the package or lightbulb.
