Re: Repair manual Model 8535 Atwood RV furnace Mark Kievit 2-22-09  
I have an Atwood 8535-iv furncce that ignites and runs fine. The problem I have is that once the rv comes to temp. you can hear the thermostat shut of the gas supply and the motor runs forever. I can turn the power off with the reset switch (turned to the off position) and I can refire the furnace after 5-10 minutes and the same thing happens again. I checked the connections and all seem to be fine. The furnace is 3 yrs old and only used 8-10 times. HELP!
Re: Repair manual Model 8531 Atwood RV furnace lionel pelletier 6-29-09  
My furnace does not work on electrical,no heat,blower stays on for approx 5min but then stop,i reset it by switching the on off button and it would do the same for another 5min;when i tried the gas it did give out some heat,but seems to be no temp reg.I'm thinking electronic controller board could be bad.I work in elecronic comm and I could probably make sense of this with the proper schematic for electrical and propane burner.
thank you so much.
Waiting to hear from you

Bob, you can download diagnostics from the Atwood web site. The below is an example. They also have parts lists for the furnaces that can be downloaded.

Re: Repair manual Model 8531 Atwood RV furnace Keith 1-1-08  
Hi Bob, Hard to say without seeing it, but you may have wasp or mud dauber nests or some type of debris in/on the burner or exhaust tube. Usually if it lights the PC board is ok, but still could be the culprit also. I'd start with pulling the burner out since it's not a real big job. You shouldn't have to pull an Atwood furnace completely out to service anything that normally goes wrong. Good luck!

The Atwood model 8531-IV DCLP in my 2012 Airstream seems to work well but was making terrible noise. Upon inspection.... when looking inside the exterior door, the mounting screw on the bottom right, the plastic hole was broken off of the motor housing. I think this has allowed the fan to interfere and make the noise. Know a fix?? Can the housing be replaced? Thank you for your consideration

Hi, My Atwood model 8531 III DCLP furnace motor sounds like it needs oil in the bearings. Is it possible to oil them? If not, must the furnace be removed to replace the blower motor? I need instructions on how to oil or replace motor. Thanks, Phil

Re: Model 8535 IV DCLP Atwood RV furnace Don Schmidt 2-24-13  
New thermostat, but furnace fan still does not come on, and there is a flashing red light on circuit board when heat is called for. I can hear the thermostat click when it is calling for heat. I have checked the electrical connections, but no joy. power is good to the override switch, but override does nothing...No fan, no ignition, flashing red light.

Re: Repair manual Model 8940 DCLP-lllAtwood RV furnace Glen Marciniak 1-31-10  
The furnace has to be reset every time. It works, but when it reaches desired room temperature, the furnace shuts off; however, there's a continuous ticking and the red light flashes on the board. When the board is reset, it goes back to working fine. Any thoughts on what might cause this?

Thanks!

to check for malfunctioning furnace and one has to look at the leds to see
if they are flashing. Where are these
leds located?

Re: Repair manual Model 8535 Atwood RV furnace John Black 3-29-10  
My atwood 8535 lV DCLP (2003) fails to stay running once the unit comes on. It does run and the pilot ignites but stops, after the third time. The unit hasn"t been ran for a year. Could the trouble be air in the line? There is a red blinking LED on the circuit board that comes on when I try to state the heater. What does it indicate?

Re: Repair manual Model 8531 Hydro Flame RV furnace Michael 9-17-10  
My furnace main control knob is leaking propane when the propane is on.
I pulled it apart and everything appears ok the rotary valve inside the housing is loose all it has is a plate holding it on with 3 screws i wondered if it was missing some parts as have on just brought the campervan.
Furnace operates perfectly but is no use if it leaks propane.
I wondered if you can buy repair kits

I have an Atwood 7920-II in my fishhouse and the thing has worked well all season until last weekend when it was -24 degrees the solenoid kept dropping out and after a few minutes it would pull back in and relight itself. Wondering if it is a fuel pressure problem or regulator problem. Hose is only 10 feet long. Thanks for any help.
