No problem. Thanks for trying to help.. It is just a confusing problem.

The capacitor should be tested but I'll leave the instructions for that to someone else.
Looking at this pic, which side of the chain gets tight when you hit the button? The side in the pic that is attached to the adjustment bolt should be the side tightening up, pulling the trolley back towards the opener head. If the other side is tighening up, then the chain position and the opener are out of sync.The adjustment bolt is there...I have attached a photo. When I shot that video with my phone it was initially inverted and I had to rotate it to straighten it out. So I dont know what happened there.
But video # 3 is what puzzles me. With the chain loose (droop), and pressing the wall switch, I would still expect the trolley to reverse since there is no load (garage door is disengaged). However, the opener attempts to start and the chain on one side tightens up. Other side is still drooping. It is as if something in the motor or gear is locking up or does not have enough juice to rotate it
Thanks WindowsonWashington! I have been trying to play with the limit switches nowTold you Mike would know.
Alu,
the door is traveling too far in the down position. Find the adjustment screw on the side or back that shows a little picture of the door going down and see which way the arrow in the picture is telling you to turn it. If you turn it in the opposite direction, the door will not travel down so far. Try about a half turn at a time. Run the door down and get it to where it just stops short of closing. Now turn the screw the other direction 1/8 of a turn at a time till the door seats nicely. On the other end, when the door goes up, it is NOT supposed to hit the bolt just in front of the motor head. If it is, then it is travelling too far. The adjustment screw for the door going up will have a pic of the door almost in the up position with an arrow pointing in one direction. Turn the screw in the opposite direction the arrow shows to stop the door from traveling so far in the up position. It should stop short of the bolt. You should be checking the bottom of the door when the door is in the up position to see where it is at in the opening. Normally it will be hanging about 1 1/2 - 2" from the top of the opening. The only time it needs to be higher than this is if you really need the extra clearance because you have a tall vehicle. Try the adjustments and see if you can get it dialed in. Now, one more thing, don't operate the door for more than 6 to 8 cycles without stopping and giving it a rest. Electrical parts get warm inside and you don't want to fry your starting capacitor. They only put so much smoke in at the factory, and if you let it all out, it won't work anymore.

Hi Mike,
As you indicated, I have been trying to adjust the limit switches with just the trolley (i.e the door is not connected). . I was able to decrease the down travel limits to position the trolley above the latch which hooks into the garage door. I adjusted the up travel to move the trolley closer to the opener end. However, I find that on each cycle the travel doesnt stay the same. It keeps keeps shifting actually, i.e the trolley moves further in the down direction and the up limit also shifts away from the garage door. On the third cycle it shifts further down and hits the stop bolt on the garage door side and then the trolley reverses. But this time the up travel is only a few inches. There seems to be something going on with the limit switches. However, I dont see any visible issue with the limits contacts. I tried most of the day. Will continue tomorrow and see what else I can find.
Thanks,
Alu
