After using a heat gun to unfreeze the entry door, and then slowly getting the snow and ice off the slide's canvas, I was able to open the slide and gain access to the fuse panel in the rear of the coach. Per the panel fuse ID, it said F-14. Pulled the fuse and it was blown. Lucky me. Currently heating the water.
I greatly appreciate all comments and especially Tom Cherry. I down loaded both files for future use. If everything goes well for another day we'll be heading south.
