There could be an obstruction in the way of the sensors,

Good Afternoon Rian,

The first thing to look at is something triping the infer red sensor or some "stop" sensor.

Release the latch that engages the arm on the door and see if the door can be manually

opened without interference. Check rails for drag and door hitting objects.

Next operate the the opener when it is not attached to the door.

This will tell you where to look next. Door causing the "stop" or somenthing with the drive.

If it is a door causing the "stop" move the door back and forth and find the place the is

hitting or dragging.

If the problem is with the drive check the wiring and circuit board for loose connections.

If all is in tact check for overheating the motor or if the motor continues to run but the drive does not move. If the later you might have a clutch slipping. If a hot motor check overloads.

You will need an electrical diagram to continue if you have not found the reason by now.

If you do not have a diagram get on the Internet and enter the manufacturer, make, model, etc. and get a diagram. It might have a troubleshooting chart with.

Good luck.

Check the bolts in the door track. These sometimes come loose and when rollers hit them it causes the door to not operate correctly.

The reason your door is reversing itself is because it is sensing resistance. When you "Help" it, your "Help" overcomes the resistance and he door functions normally. As doors age and things settle, sometimes what was a new free flowing mechanical device over time, doesn't "free flow" as well as it used to when new. This is expected. Here is how to overcome that issue...

Up on the motor should be 2 dials. Sometimes these are just a shaft about 1/4" in diameter sticking out of the back with a slot for a screwdriver and sometimes you have to insert a small screwdriver into a hole. There should be some type of directional indicator telling you which is more and which is less.

These are upward and downward force adjustments. Increasing the downward force slightly will tell the system to push through a greater resistance in the down direction. Increasing the upward force slightly will tell the system to push through a greater resistance in the up direction.

Try increasing the upward force just a little. If that does not solve the problem, try increasing it some more.

It would also be a good idea to have a helper watch the rollers and tracks carefully as you are working the door to see if there is southing that might be impeding the doors free movement which might be visible.

Also, lubricate all of your rollers. Use a silicone spray. Don't spray where they roll in the track but rather into their axles. Please let me know if this helps you solve your problem.

Check your rollers and for anything that may be loose then check your cables / springs see if they not broke.

If the garage door stops on the way up using the garage door opener than it may be heavy & out of spring balance fo the GDO is shutting off when it feels resistance from the weight of the door.

TO TEST THE DOOR BALANCE: Disconnect the garage door from the garage door opener (GDO) & raise it half way manually & let go of the door. The door should sit there balanced against the pull of the springs. If the door slams down it is out of balance. Call a garage door pro to get it fixed.

IF THE GARAGE DOOR IS IN BALANCE: Lube the rollers & spring/cable pulleys with spray oil & check the GDO open pressure switch. Refer to the owners manual for adjustments to your GDO.
