Yes when the one under the sofa does starts it is with the one under the sink cabinet in the kitchen. One additional item that leads me to look for a loose connection, yesterday while watching my Packers loose I got slightly disgusted and gave the end of the sofa a good kick. The fan came on, but went off with the one under the sink.

Thanks for the link I will read the post to see what I can learn. Looks like the heating units are different. Mine is smaller, made by Aurora, a German Company. It can only be removed from the top by removing the sofa.

I will let you know what I find.
