Pull the cord to release the door. Make sure it works right, your
problem could easily be a broken spring, a jammed roller, a bent track
or the like. (Yes, I've see a broken door cause "one opener doesn't
work, the other does", more than once.) Assuming the door is fine,
train your remote to open your wife's opener, and see if that makes a
difference. If it does, change the battery in hers, train it to your
door, and call it day. If it doesn't, go buy a new one. I'm pretty
sure chamberlain are using the same mounting setup they have for many
years, so that it's a breeze to replace just the head.
If your door is broken, call another company to fix it. And check the
other side, it may be failing the same way.
