My garage door has randomly decided to not close. The door will close a few inches to a few feet before reversing. It may take 2 attempts of 10 until it will fully close. I have checked:
- Sensors are properly aligned and cleaned.
- Sensor wires are not cut or damaged from what I can see.
- This happens with both the remote and wall mounted opener.
- The light on the back of the motor blinks 4 times, which according to the manual is a sensor issue.
- I have tried to adjust the down force with no luck.
- If I manually close the garage, the garage door chain will run with no issue.
Does all of this mean that there is an issue with the actual door?

Does this mean you detached the door from the drive?
Not necessarily.
It could be the chain is fouled somehow, or that the door opener casing has shifted or loosened.
In my experience in the damp Pacific Northwet is that the (wooden) door has swollen with the onslaught of autumn rains and now binds slightly against the door frame.
To confirm this as the cause, raise and lower the door manually being careful not to push or pull the door into or away from the frame and see what parts might be touching. If the door is large, a helper is quite useful.
Also, inspect the rails and roller guides to see if there is anything amiss. Give all the parts a good firm wiggle to see if they might be shifting under the strain of the door moving.
