Has anyone ever hear of something like this? Does it sound like defective
oven? How to fix???

My neighbor just had a set of new garage door openers installed. The
remotes didn't work. Installer couldn't figure it out. Gave up and removed
openers.

Second guy with different openers had same problem but finally traced it
to the Kitchen Aid Superba gas oven (NOT microwave) since everything works
fine once the oven is unplugged. I THINK the oven is on a different
circuit than the openers. It seems to be putting out some frequency that
is jamming the remotes. The oven does not have to be on to jam, just
plugged it. Installer says he's never seen a problem like it.

What could cause an oven to do this???

Thanks for any comments or suggestions.
