Test the sensor eyes by connecting them to short wires directly at the motor unit.
Sears garage door closes then reopens halfway.
They can only open it.
Fast easy step by step process on how to properly program your garage door travel system.
Your garage door is programmed to travel a certain distance before it closes.
Now the green light at the back of the unit keeps flashing.
But changes in weather conditions can causes your garage door components to shift or contract.
As these wires short against the housing the electrical impulse causes the door opener to activate.
This requires a simple turn.
When this happens your garage door will only close by holding down on the wall button until the door fully closes.
Replace the garage door opener safety sensor the safety sensor has a pair photoelectric eyes at the base of the rails one eye emits an infrared beam and the other receives it.
If it closes before that distance has been traveled it thinks something is wrong and it reopens to help prevent any damage or safety risk.
To test trigger the remote while standing close to the motor unit if the door opens consistently from that close distance interference is likely the problem.
Quite often the cause of your door s malfunction is an improperly set garage door limit.
I have a craftsman 1 2 hp opener.
To solve the problem identify the source of the radio interference and either move it or turn it off.
And the door opens half way and then goes in the reverse direction.
If there s anything stuck to the bottom of the door such as a leaf a small piece of paper or any type of.
If an object person or animal blocks the beam the closing door reverses direction.
There may also be loose wire connections inside the button housing itself.
This method is the only way to override the safety sensors and close the door.
A garage door that only opens halfway becomes a nuisance for many reasons.
Some older garage door openers do not have nicely labeled adjustment screws for force and travel limits.
Check the bottom of the door.
The one that was working isnt working anymore.
The problem is often intermittent.
The symptom of this is a garage door that is in constant motion opening fully then immediately descending only to start the same cycle again.
I simply opened the cover case to look at the wire sequence.
If it still reverses raise the door halfway and stop it.
