An acquaintance at yesterday's neighborhood picnic asked me if I could
help him with a problem. He said his opener (make unknown right now
until he calls me to tell me) has stopped working. He bought a pair
of new Genie sensors at HD, but they didn't help. He said one lights
red okay, but the other does not light green. He called Genie and
they said you cannot use Genie sensors with other makes.

Is this true? Or, in other words, are sensors interchangeable, or can
you only use sensors on an opener of the same make? I really didn't
know, but thought I'd ask here.

Thanks

Hard to say; maybe. You'd have to know whether they're normally open,
normally closed at the housing, voltage/feed requirements, etc., to be
certain. I had a genie opener once that was so genie-customized nothing but
a genie or a gerry-rigged part would work with it. Nothing was standard on
it.
When you get the model/make, try to research it at the mfg site; if they
give specs you might be able to tell.
