update.... Went back to the home again today.. (No Heat) I looked so hard for a issue in the control box.. No dice! T-Stat bad again. I go to the truck and put my tools up and put on rubber gloves and 2 screwdrivers and a new Honeywell t-stat. I don't know how long it will last I just hope it last till they leave. OH.. They now seem to have at least a dozen outside cats.. Just keeps getting better all the time.
