Troubleshooting Garage Door Opener



Question:
Agreed, which is why I replaced the switch, then disconnected it for a period of time. Unfortunately, the symptoms continued during/after both of these tests.

Answer:
Shouldn't have any thing to do with the hard wired switch, but are you located near a military base. The military recently took back and started using frequencies that garage door openers use. Sears recently posted a notice that some older openers would start having difficulties because of this. I seem to remember that they came up with a retrofit of some kind that would alleviate the problem. And of course, all new openers now use a different frequency. I'm glad you guys had an answer. I was stumped. If your advice about shorting etc. the antenna doesn't work, but he's certain that's the problem, I'm sure he can open the box and cut out a part or two until the antenna doesn't work. Then there's probably a universal remote/receiver whose output will connect in parallel with the wall button. I have one from a Zenith TV from 1962 that the OP can have, but they probably make them with transistors now. (There's always X-10, if nothing simpler)
