Does it hurt the motor or any other parts if you leave a rollup garage
connected to a garage door opener partially open?
The door opener manual recommends against it because someone could
become injured if they are sitting under the door when someone touches
the remote or other controller, but it is not a safety issue in this
case since no one will be sitting under the door while it is partially
open. I am more concerned that it might be a strain on the motor to
hold the door partailly open for hours.
If the garage door is partially open it will be convenient since it
will allow air to circulate in and out while still providing some
I connected my photocells to (in addition to the garage opener) trip a
signal alarm. The door is open only enough so anyone (except for the
occasional critter) that could possibly fit would trip the light beam.
