Genie screw drive stops and starts

I have an older Genie screw drive (sd9500) which all of a sudden has started acting odd. It stops partway down and partway up. I tried cranking up the the safety adjustment and even disconnected the safety switch (when there is too much vibration the safety hub hits this switch). I thought it might be the motor thermal fuse but the motor starts right up after a press of the button....doesn't need any cool down time. Now the door goes up a little and down a little....after a minute it tries again. Btw....it never had a photo sensor safety device so that gets ruled out. Being an older unit it is pretty basic....I just can't figure what else it could be. Thoughts?

Yeah! Tell the succo company to stop porting SPAM here.

In case you don't know -- only one company has an opener without sensors.

No reply to succo sites....sorry!

Disconnect the door from the opener and see how it opens and closes, and if something is hanging up halfway up and down/

: It opens and closes very easy while disconnected. It turns out it was a stuck button on the remote control. Go figure.

It sounds like it is binding. Check it by disconnecting the motor and open and close it manually. If a spring is broken or if the springs are unevenly supporting the door, it will bind.

Note: Adjusting springs can be a dangerous job. If you are not sure you know what you are doing, leave it to the pros.
