My Overhead door model 555 sticks in the open position. It seems like
the unit is not sensing when it is all the way open and it goes too far
and gets stuck. I have tried lubing it up etc and no luck. Is there a
way to retrain it to not open so far? Is there a sensor that tells it
stop before opening too far?



Yes there are limit switches on the track, on the models I am familiar with.
See if the rear limit switch is almost back to the motor. Look for an
indentation where it belongs.


Hi,
Or relay which is controlled by the limit switch.
