Here is the latest in the garage door opener saga. Edison Co. came to
my aunt's house and had her turn off the main power breaker. He then
asked her to have the neighbors try their openers. They worked
perfectly! The problem seems to have been related to a surge
protector she used on her computer system, but I don't know if that's
the final answer. Hers does work fine now. I have been trying to
figure out how a surge protector not connected to the opener could
affect her opener as well as the close neighbors. Must have been
putting out one heck of a spurious signal.


Very interesting find. Please post any further updates on this. I'd
like to know if the problem would transfer to another home if that surge
protector is moved to it.... also, might be interesting to put a high
frequency scope on the AC line going in,and coming out of that protector
to see what is on the 120V inputs and outputs.
