Thor Motor Coach Products
I recently returned home from Florida in a significant snow storm. Upon my return I parked the MH in our driveway over night. The temperature was in the high 20's and since I had not winterized at that point I plugged the unit into our 30 AMP circuit and turned the furnace on. At some point during the night the furnace failed although the temperature had continued to rise and the snow was melting very quickly. The amount of water running off the coach was amazing. After I winterized the coach I called my dealer and he advised that there is a problem with the Atwood furnaces on Thor products. Ours is a 2015 27.1 Model however the dealer indicated the problem goes across many Models. It seems that the vents in the furnace door (access panel) are punch inward rather then outward and water can simply flow into the furnace chamber. This causes the furnace to fail and sometimes (as in my case) blows the circuit board which requires a replacement. Sometimes the fix is to open the furnace access panel and blow out the moisture. My dealer has been attempting to get replacement doors / panels for the furnaces but at this point there seems to be a finger pointing contest between Thor and Atwood. The dealer feels that there should be a Recall issued since the problem seems to be growing and he has numerous units in stock with the faulty doors. A simple process of washing the coach can cause the problem. In any case I just wanted to alert everyone to the issue and It may be a good idea to look at your access door / panel to your furnace. Hopefully Thor and Atwood reach some agreement to a solution and begin to provide a fix.
