I have a Lift-Master with a 1999 build code in my place. It failed maybe
6 years ago, and after not being able to see anything defective on the
printed circuit, I grabbed the soldering gear and "re-flowed" or fully
re-soldered the whole board. Voila! It worked. Chamberlain broke a real
basic engineering rule: Do NOT use solder to mechanically secure
components to PCBs. I also glued all the offending big pieces down with
- forget exactly - sillycone or hot glue or similar. Better engineering
would have done that in the first place, or potted it, or put a ty-wrap
in, or some bracket.
