It seems to not turn off, keeps buzzing, at the end of the raising or

but now its cold it has failed twice this month same way.

My question is, are the replacements simple enough to do? I don't need
to touch the door or tracks or springs, but I have never done this
before. My current one is a chain drive All-O-Matic. Inside the box
there is a motor driving a wheel with a belt. The door is a double.

Any recommendations?
Sounds like your limit stop microswitchs are going bad. Luck in
finding new ones. Be sure they match. If you have checked on top of
opener to make sure the stop switch areas are not gummed up with
grease when it gets cold and gets thick. Clean with electronic parts
cleaner. unplug operator first though. See if this helps before
messing with or replacing microswitchs
