I have no problem openning my garage door but it won't close. If I push
the botton on the remote control while the door is open, it will try to
close but will either immediately or in a few seconds reverse . If I
release the door from the door opener, the door opener would work fine.
Thus, it seems the door is making the door opener mulfuctioning. What
could be the reason?
Should have clarified that in my original posting. My fault.
I can open and close the door by hand when it's not bound to the door
opener. Also, the sensor light stays green during the whole process. The
door opener is made by Sears (Craftman brand). If there is something
blocking the sensor beam, the light should turn yellow. It does not. Yet
the light on the door opener, not the sensor light, flashes as soon as
the door reverses, behaving exactly like either there is an obstruction
or something is blocking the beam.

You might have a completely different problem, but it is worth a try.
I had the same problem..... I have a Sears Unit and the electric eyes were
slightly out of adjustment. They showed a green light (Slightly dimmer)
too. Also might want to wipe the lens on them too.

Make that #3 having the same problem, but for me it turned out to be a
microswitch going bad in the travel limit adjustment assembly.
It's not the photo-cells. If it were the opener wouldn't work fine
when the door is dis-connected. There are a number of possibilities.
1) Too much spring tension on door when open
2) Bottom of door binding against jamb as it comes out of the curved
part of the track
3) Down force or clutch force on door opener set too low
4) Defective logic board
5) RPM sensor going bad
6) Chain or belt (if you have that type) too tight
7) Too heavy of grease on screw drive type
It would help to have the brand, type, and approx age to narrow the
