Genie 2646 LL Code

I have a Genie 2646 that only goes up 2-3’ then stops. Code is LL whic I see us out of level. It’s in my shop in concrete, nice & level. I see the switch in the center when slightly raised and bubble is nearly perfectly in the center. Can I jump the 2 wires going to switch to override it? Or, what else do I look for? Bubble switch moves freely. Moving it slightly with a small bar has no affect. Thoughts?
