Does anyone know how to fix this.
Garage door will not close unless i hold the button.
It is a craftsman.
One sends a beam of infra red light to the other.
They can easily become mis aligned due to bumping twisting and loose mounting.
My garage door will open by just pressing the button once but to close it i have to hold in the button until it fully closes.
If anything interrupts this beam of light the garage door will not close and the ceiling light on the opener mechanism will flash as mentioned in the previous step.
Depending on the brand.
When you can close the door with the wall button by holding it down until it completely closes and the remotes only make the door move a small amount and the door returns that is the sign of the safety sensor system.
