Garage Door Reverses 1 From Ground

[Wade Garrett]

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?

If you disconnect the opener and raise and lower the door manually, do you notice any binding at 1 foot level?

Sure seems like an obstruction ... Perhaps the obstruction isn't at the bottom edge of the door opening - but is happening further up on the track ? or something snagging near the top of the door ? I have rough storage over the garage door and on both sides of the door - and I can see how it could happen to me. John T.

Have you looked for a leaf or similar hanging from the bottom of the door?

It could be binding. Maybe the rollers need oiling. While doubtful, could be weak springs.

That can do it as it is similar to hitting an obstruction. Some openers also have a setting for travel that may habe gotten out of adjustment.

My Genie (screw drive) was doing that about a year after I had it installed. About 7 years ago. The installer came out and replaced the circuit board. Said it was a known failure, and he had plenty seen plenty of them.

No, seems OK.

This one has been in service for many, many years-- at least 15, maybe more...

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

I may just be worn out. Maybe the screw in binding. I have a screw type opener and every couple of years I hae to give the screw a good spray of some Tri-Flow to keep it lubercated.
