I have a linear garage door opener.

for some reason the opener will only open if the sun is not hitting the slab, i guess this is a reflection on the beams, perhaps I can move the beams and take care of this.

but now the operator will only open to mid point, it will close all the way down, but open to mid open.

I did tinker with the screws a little but not sure what to do.

once when I tried it, the remote would not open the operator, after a few minutes, it would again. Then the wall swithc will not open it, but after I wait a while, It will.

what the hell??????????

about ready to throw this damn thing away and go get a genie,
any suggestions????
