I finally called in help. What is it with me getting around to asking for help? Took me long enough. But, ta da!!! Success! A special thank you for all who offered assistance both on this site and at KCL. Thanks to my friend in the warm and wonderful south for suggesting I tape the switch in the off position when I realized I couldn't unplug the unit. Thanks to my friends in the cold and north wet mountains for reminding me I may want to know where the water cut-off valves are (a funny story they tell very well - especially around the dinner table). And to a friend I've never met in Florida for suggesting an allen wrench that will actually fit. You guys are the greatest!
Okay, now I can think about setting up the christmas tree. That should keep me out of trouble for a little bit. Or not?
