'02 Eagle M Series T-Stat Issues-Resolved!!
After 6 years of dealing with what I thought was a defective T Stat, (Have replaced it, installed RF chokes, and more) I think I finally isolated the problem. On the M series floor plan, the heat duct is under the kitchen sink and there is a supply vent at the bottom of the 4 drawers just above the floor. The thermostat is located above the stack of drawers (About 2' above the countertop) There is a wire chase where the T-Stat is mounted that runs all the way to the floor to the area where the duct work is. I noticed that when I opened the drawers, they were extremely warm. I pulled the drawers out and found that the duct work was not mounted to where the heat vent was, causing most of the hot air to escape into the cabinet area, up the wire chase and make it's way to the T Stat. I fastened the ductwork to the vent and also purchased some insulation to lay above the duct work and seal off the wire chase. Then I duct taped the edges to seal any heat that could escape. This seems to have taken care of the issue. This problem has to have been with this coach since day 1 and as it came from the factory so I wonder how many other M series are experiencing this problem.
