Thanks to everyone for your great suggestions! Ron, we did what you suggested and inspected every fuse and made sure none of the breakers were tripped. All fuses were in good condition, so we did what everyone suggested, we called Kermit.
Kermit is the proverbial "answer man"! He told us how to take off the upholstered panel on the front of the couch so that we could inspect the switch, the wiring, and motor. Sure enough there was a yellow wire that had become disconnected from the splice near the motor. That was the problem and I am very happy that we know how to fix it now!
Again, thanks to every one for your help and advice. And, 2 Frazzled, I did check all of the owner's manuals but did not find any info for the tri-fold couch/sofa bed, which is odd because there seems to be papers on most every system in the coach.
Happy travels everyone. In a few weeks we are headed to the Canadian Maritime Provinces and we don't plan on coming back to the Midwest until mid to late October. We'll be joining a caravan (Adventure Caravans) for part of the trip. Can't wait to get on the road again.
