Heads up on surprising repair.
My garage door stopped working a day or so ago. I checked everything out
that would normally lead to a failure and found nothing. Eventually I
pulled the printed circuit board. I found an overheated section on the
circuit board, right next to one leg of a relay. The track was blown. I
figured the relay was shot, so I unsoldered it, then pulled the cover off
the relay to take a look. The relay looked fine, so I cleaned up that
terminal leg, which was corroded and soldered the relay back on the board.
I added a jumper to a good part of the circuit board track and it's working
again. I suspect one of the original solder joints was marginal and it took
15 years to finally overheat and burn through.
Craftsman is made by Chamberlain. They also make Lift-master, so this same
issue could affect any of these brands or another brand. It was just so
weird I had to write it up.
The really odd thing this week was about relays. Relays are pretty solid
and rarely fail, at least in my world. A few days before the garage door
opener issue one of the girls at work was having an issue with her car's
A/C. That was a blown compressor clutch relay. Watch your relays folks.
They are failing fast now. Must be sunspots or something.
