Fix Garage Door Bracket

When I was working on modifying my garage door opener, I found two things:

1. One of the failure sensors was tripped; there are several, but the one that got me was the obstruction sensor. It was incredibly easy to bypass by short-circuiting the sensor's connection with a jumper wire.

2. The communication may be off, especially since you replaced the board and remotes sometimes don't clear their memory so well; check the blink patterns in the diagnosis manual. The blinks may indicate that the remote's rolling keycode pattern is incorrect. This is exactly what happened to me.

Verifying that the door operates correctly and without excessive force with the opener disconnected is a required first step. If the door jams, the opener cannot be expected to work well.

Given a mechanically sound door system that operates properly by hand, odd behavior in "modern" (25 years or less, perhaps) garage door openers is almost always a sign of "time to replace the logic board."

It's actually a slightly fraught choice, since a logic board is typically 1/2 the price of a replacement opener, and the replacement opener comes with a warranty, while the logic board often does not, and there's always the possibility that it won't fix the actual problem.

That said, I've replaced one and it did cure the problems that opener was having (which were life-threatening and probably resulted from a nearby lightning strike - I also added a surge suppressor to the outlet.)
