Kinda stumped here guys and could use a bit of advice..
in the last little bit the automatic garage door has been acting up...
Sometimes it will open.. other time open a bit, and other times halfway.... then it jerks to a stop..
if I pull the red rope.. it opens without a hiccup.. put it under load again and it starts to act erratic again...
I picked up some garage door lube and sprayed the pulley assembly on the door, the wheels and the track the "scuttle?" travels along...
same issue...
it has worked flawlessly in the past..
does anyone have any ideas of things I am missing? is it time for a new one??
