fan starts by itself...
Posted: Fri Oct 14, 2011 10:34 pm
I have a coleman evcon standard blend air 2 propane furnace. The fan will kick on by itself, with the t-stat in the off position. Does it sometimes in the morning, sometimes in the evening. It will run for awhile, kick off, then right back on again. A/C works fine and so does the heat. Also, after the a/c runs its cycle and kicks off, most of the time the fan will start right back up again. This seems to happen in the spring and fall of the year, but never in the summer, doesnt make sense. Diagnostic light stays lit indicating normal operation. Also, installed new t-stat, but that didnt help either. Any ideas?
