Dave,
Since you have two of these you can do some comparisons.
Disconnect the openers from the doors, then open and close the doors by
hand, comparing how much force is needed at different positions.
With the doors disconnected, run the openers up and down with the remotes to
see if they both close correctly.
This will isolate the problem to either the door or the opener.
Door rollers get worn, dirty and bent, so you may need to replace one or
more of them.
Give it a bit more diagnosis and then let us know what you find out.
Peace,
Pat

Subject: [Shop-talk] Garage door opener problem
I have a pair of Chamberlain PD200 openers in the garage. They are about 15
years old and until just recently have been flawless. Lately the one on my
wife's side (naturally) has gotten flaky. As soon as you push the button to
close it, it reverses and the light flashes. Opening is normal. If you
hold the wall mounted (hardwired) button down it will close and stay down,
but it will no longer close with the clicker. When the problem first
started the door would partially close before reversing, but now it doesn't
even move.
I adjusted the photocells, lubricated everything, and adjusted the
sensitivity pots and turned the open and close distance pots through a few
turns. For a few cycles it worked ok and then reverted to it's bad
behavior. I called the local residential/commercial GDO business, who also
installed the opener in my shop a few years ago. I wasn't here, but
according to my wife he lubricated everything with "something heavier than
WD40", "adjusted" it and left. It worked for a week. I looked yesterday
and he had turned the sensitivity pots all the way up to 11.
So, $100 down the toilet.
The one on my side works flawlessly....so far.
This is a standard, chain drive, 1/2 HP rolling code unit, nothing fancy.
I can buy a new one at Home Depot or Amazon for $125 or so. Before I do,
anything else to check?
thanks
