Garage door intermittent stopping.
Near the bottom of the door track on both sides are electronic eyes that require a clear line of view between them.
The safety sensors may need adjustment or realignment.
The garage door is a pretty heavy unit and the track offers some resistance.
Also the most unlikely little things can cause electrical interference with the circuit.
Adjusting the limit switch will stop your garage door from behaving erratically.
Locate and eliminate the source of the rf interference.
If the remote works only when held within a few feet of the motor unit rf interference is probably the problem.
If your garage door is closing fully and then reversing to open again then it may be due to a problem with the close limit switch.

This requires a simple turn with.

If there is too much resistance the garage door opener stops and usually blinks it s light once or twice as a warning.
If your garage door opens and suddenly stops it might be because of your logic board.
