@Matador – Hello and thank you!
Thanks for the clarification on the lack of a sensor. I thought I’d seen one mentioned somewhere else, but likely I misunderstood.
I can gently “force” the doors closed, but it feels more like my closing the doors forcibly than “assisting” the motor. When I apply light inward pressure, they start to close, move inward about 1/4 of an inch, and then move back out to the fully open position, just like when I don’t apply any pressure.
I can then manually force them closed with gentle inward pressure, but don’t feel any “cooperation” from the mechanism.
@guy – Thanks for the link!
