When I attempt to open my garage door using the opener, the door stops moving and the opener emits a terrible sound (like an impact drill or a hammmering sound) that I assume is the opener's carriage riding on top of the screw without moving.
I've taken a short video of this happening to illustrate.
This has gotten progressively worse over the past week or so. When I first found out it would lift a couple of feet before stopping like this. A gentle lift would assist it back into motion.
When the door is disconnected, it seems to lift as easily as it has before. I don't feel it binding or see any of the pulleys or rollers sticking. I've tried lubricating the rollers where they're held to the door to no benefit. The springs have been replaced in the last couple years but not so recently that I'd associate the springs with the issue.
How do I fix this?
The opener is a Genie H6000, specifically an H6000-07/M
The screw and coupler appear to be turning freely without stuttering. https://youtube.com/watch?v=iXXxmTjnJmM
I can't tell if there's anything abnormal at the trolley or not, other than the trolley not moving. Here's video—the pitch alters when I apply a little pressure to see if the front of the trolley is engaging or not. Either end of the trolley has grease/lubricant on it (which has not been recently added).
- Trying to record this to share seems to have worsened the problem so that my trying to assist it open doesn't allow the trolley / carriage to engage. I'm starting to think buying a new carriage is the next logical step, but this isn't my wheelhouse.
