I've installed a few Over-head Garage Door power operators. Per instructions the springs are adjusted to where it does take much to lift the door open. And if the power operator were disconnecded the door would fall closed without slamming. Or because of friction, stay where disconnected.

"in general"........
How much weight can my garage door opener handle? For an automatic garage door, the lift of the weight is subject to the horsepower of the garage door opener. A half of horsepower can lift roughly around 300 pounds. This is the average load of a two-vehicle steel door, and a one horsepower door opener can, without much of a stretch, lift roughly 400 pounds.Nov 30, 2019
