This is a true story. It happened to me last week. It's not a big deal, but it could save you hundreds of dollars trying to find a solution. I'm posting this in hopes that one day it could help you or someone you know.
Last week my wife is leaving for work. She gets in her car, opens the garage door, and backs out into the driveway. She tries to close the garage door with the remote in her car but the door won't shut. She get out of the car and walks right up to the door, tries again, and this time the door closes.
When she gets home, she asks me to change the battery in her remote. I do. The next day when she leaves for work, the same scenario happens. The door won't shut from her car, but it will if she walks right up to the door.
She tells me there is something wrong with her remote and tells me what happened. I try it with the remote in my car, as well as the spare. Same thing happens. The door will open fine, but it won't shut unless you get right up on the door.
I call the manufacturers "Tech Support". I explain my issues. The first thing he asks me is: "Have you changed the light bulbs in your door opener lately"? I tell him that I did. I changed the bulbs from regular to "LED".
He says to me: "How long after you changed the bulbs did this start happening"? I said "the very next day". He tells me: "Remove the LED bulbs, put the old ones back in, and your problem will be solved".
I did exactly as he said and all 3 remote openers work fine. No issues. He also said that some brands of LED bulbs will work fine but I would have to try different ones and see which ones work and which ones don't.
Who would have thought that certain brands of LED light bulbs could interfere with transmission signals from a garage door opener?
