Thanks doordoc. That's what I was looking for. My aunt's door is not
the one with the open halfway then close problem. That's across the
street.. My aunt's won't operate at all with the remotes. The house
beside her has the same no operation problem. I don't know how far
this problem spreads in the neighborhood. She has already paid the
original installer $120 to troubleshoot. The installer is convinced
it is an interference problem. I am going to try to find out the make
and model to see what I can learn about frequency, etc. If I can find
out, I will post it here for comments.

With all of that said, as others have posted interference will not
usually stop a closing door in mid travel. There may be some other
issue there or it may be that your aunt is holding the button too long
when she can't get the door to work & the opener actually ends up
receiving more then one signal from the transmitter.
