OK!!! Took Carl n Susan's advise and looked around for the answer as they suggested. Could not find it on our blog but found the answer, I hope, on Heartland's Blog -
http://www.heartlandowners.org/showt...Code-Quick-Fix - same problem as I had. Held a strong magnet on the board just below the red light (while the frig was on) and "click", the red light went off. So far the "Li oP" message has not come back on.
Thanks for your help! It's off to the Keys tomorrow! You guys are the greatest!
