When I tried to open the door, it moved about three inches then

It has 120 to it, 24 v to the wall switch but does not activate with

Thanks,

Must we have a secret code to know what an SD 9500 is? I'm going to
guess it may be a garage door? If so, check the safety reflectors to
see if they are properly aligned.
I get that sometimes in the late afternoon when the setting suns shines
directly into the safety reflector.

Then you should witch around safety T beam in position. Let the
transmitter face the sun.
Good idea! Will add it to my ToDo list :-)
