Got an older model Genie screw drive garage door opener (IS, ISL, IC
series) that started reversing the lowering door when its bottom edge
reached about a foot from the ground yesterday. It happened when
activated by either the remote transmitter or the wall switch

I know that if the object-sensor safety electric eye is obstructed, the
door reverses immediately after it starts down-- but I can't figure out
what would cause it to reverse at the one-foot level.

The opener has worked fine for years. The stop-activation levers for
raising and lowering haven't moved and are in the correct place, I
haven't touched the closing force or other adjustment screws on the
motor head, and the tracks and rollers appear OK too.

Ideas?


Something stuck to the door interrupting the safety beam?? About the
right height - - - -
