This garage door problem really has me stumped.
Fortunately here in Southern California it doesn't rain too often (except for this year).
But when it does my garage door halts about half way down and then retracts (i.e. opens).
I know this can be a symptom of a door sensor problem. But I just moved in and the infrared sensors, which are usually on either side of the door near the floor of the garage, cannot be located.
It is a Sears 3/4 HP Garage Door Opener (chain drive). Similar to the GDO at
I lubricated all of the recommended places and even increased the screwdriver adjustment for the door closing speed/pressure. Still no joy.
Any ideas?
As always, thank you for your time.
