And finally, the answer. Our air conditioner went out a couple of months ago and I had an RV Service come out and replace it. I called her and she says that it's something to do with the programming that needs to be reset. She is checking into the problem and is supposed to get back in touch with me. Thanks for your responses, and I am glad that I am not crazy, no heat on that darned thermostat to be found, lol
