Did you ever figure this out I have the same problem with mine?

That sounds pretty normal for most furnace/heater products. They run the heating element with fan for a cycle then after the heater reaches temperature it will shut off and the fan will continue to run to cool the element and to circulate the heat that it produced. If you want the manual for this product it looks like you can get it here: http://homeappliance.manualsonline.com/ex/product/headline/m/Coleman%2BEvcon/d/furnace/p/DGATO75BDC

google it! use the specific search terms, Coleman power pulse 1850 - it worked for me!

I would suggest to go to a full service sporting goods store, dicks, gander mountain, bass pro shops outdoor world. If they cant help, go see a seamstress.
