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.
