genie garage door opener that won't open
She also managed to lock the door down once by accident, using the original locking mechanism built into the door. We simply removed the two horizontal locking bars that extended into the door track, so that she couldn't lock the door from inside the garage. (She doesn't have keys to the original lock anyway, so no big deal.)
The fact that your unit appears to operate correctly when the door is disconnected from the unit, and I'll assume it worked fine before, seems to point to one of the two items I mentioned. Other readers will hopefully provide other possibilities as well. Good luck - let us know what fixes the problem!

If the door is working and adjusted properly it should stay open by itself when opened about halfway.
If all's well with the door operation, then get the opener fixed or replaced.
