I have an Atwood Hydro flame 8525 IV Furnace installed in my RV. The Furnace goes thru the correct sequence of operation until it get to the lighting of the flame. I hear the gas valve open and the igniter sparking. It doesn't seem to start. The furnace does this three times and then shuts down and blinks a led three times ( for three times ). I can smell propane at the exhaust port. The other gas appliances seem to work fine. Any idea what is causing the problem. The furnace is a very closed in area with very little access. Do I have to take it out to fix it? The discharge seems to go below the floor.
Hi Ron, Seldom do you have to remove an Atwwod furnace to fix anything. If you're getting spark and a propane smell, I'd look for mud dauber/wasp/bug nests in the exhaust tube or on/in the burner area. After you pull the exhaust tube, Turn off propane, disconnect the propane line at the burner, remove the screw on the front round edge and 3 - 4 screws in the back around where the exhaust tube goes, disconnect the igniter (red) wire and black wire. Pull out the burner. Hope this helps. Good luck!
I have an atwood 8500-iv series furnace in my 5th wheel. The blower comes on and it tries to light but won't. If I crank up the temp., it will fire up and run. What would cause this?
