Garage door opener gone haywire

[peter d]

We recently had some severe weather here in southern New England, and as a result there was much damage done to the electrical distribution system. I did not lose power at my house but there were several "blips" where the lights would blink for a second, presumably when a "down" area was being put back on line.

Anyway, I noticed this messed up my Genie garage door opener. If I opened the door after one of these blips, it would not close again. It would close part way, then go back up. The solution was to turn the breaker off for a few seconds to reset it, and it would go right back to normal. Any ideas?

Disconnect the power to the opener and it's controls and let them 'go to sleep' for about 15 minutes. Then power it back up and let it perform an orderly re-start.

90 percent of the time I am called to similar problems that's all it takes.

I disconnected it for 2 minutes and it went back to normal. I'm just curious what causes this...it seems like it shouldn't happen with all the technology we have in this day and age.

What usually happens is that the power flickers and the unit does not perform an orderly shut down which corrupts the memory. The memory is powered (usually) by capacitors and by totally discharging the caps you erase the memory. With a blank slate to start with the microprocessor will write everything it needs back onto the memory chips and when that happens all is well once again.

I have only seen bad results horseing around with garage door openers(residential) I have had verry good luck with commercial door openers others have not been so lucky.
