I consider myself to be pretty handy around the house. With the help of the internet I'm able to fix most of my breakdowns. Then came my garage door opener. I installed the opener as my home didn't have one when we moved in, everything was fantastic for 3 years or so. Then I got a new truck and decided to try to program the mirror button in my truck to the garage door. Everything went haywire. The door would open and close intermittently using all of the remotes, but would always work using the hardwired button in the garage. I reprogrammed, scratched my head, then reprogrammed again. This went on for over a year. Well, with the help of a lucky hit on my latest Google search, I finally found the answer. At the same time that I did the first programming of my truck, I also changed the light bulbs in the garage door opener. Unfortunately I decided to use new LED style bulbs. The bulbs apparently put off a signal that interferes with the opener, so whenever the lights were on then the remote wouldn't work, but if the lights were off it would work fine. In hindsight it all makes so much sense now. The moral of the story is to stay away from putting LED bulbs in your garage door opener.
