I really doubt it is interference related. It has gone for five weeks now
and not worked one single time. It works perfectly on the button,
hard-wired control.


It did this same thing about 3 months ago. Would not work for about a
week (three different remotes would not work) , and then it worked again
for 3 months until now.

The universal remote looks like a good idea. Did someone say they have them
at Lowe's or Home Depot ? If so, I wonder what department to look
in................
