LED Lightbulbs Cause Garage Door Malfunction
BENTON -- Homeowners and businesses in Southern Illinois are discovering a frustrating problem. The newest LED light bulbs can cause interference with garage doors.
Many people use a remote to get in and out of their garage. The Door Doctor in Benton has discovered a new problem plaguing that equipment.
"In the last four to five years, they're starting to, out of nowhere lose their range," said owner John Reece.
When Reece tried to figure out why the complaints were happening so often, he found that certain LED light bulbs interfere with the radio frequency between the remote and the garage.
The lightbulb can be on anywhere around the house and cause the garage door not to work.
"You have a bulb that would be malfunctioning, emitting some type of RF (radio frequency) signal out of the bulb. The bulb may still appear to work properly and is doing what it's supposed to do but it's not supposed to emit a signal to interfere with other things in your house," explained Reece.
Reece said, as LED lights become cheaper and more popular, more and more people may run into this problem.
"LiftMaster has come up with a dual board that does dual frequency now," he said, "In fact, that's all we use now. We started about 4 months ago."
Reece said if you notice your problem is intermittent, first check your remote's battery. Next, check your bulbs, you may just need to buy a new one.
"If you have done that and it hasn't taken care of it at that point, you probably need to contact a installing dealer," said Reece.
Two other options are available: purchase a device that reduces radio frequency interference; or replace the control board in the garage door opener.
