Atwood/Hydro Flame 8525-IV-DCLP Furnace Bob 1-12-06  
The furnace is in a 2005 Layton 3260.
The furnace cycles as it should until it gets to blower shut off, it doesn't. It will run until I pull the fuse to the furnace, it will then stay off until thermostat calls for heat, then cycles as it should, except blower will not shut off until I pull the fuse. Circuit board tests OK. Thermostat is a Duo-Therm climate control center.
Thanks for any help.......Bob

Above unit starts up, feel heat coming from exhaust, then shuts down, after 30 secomds.
The red light flashes three times, indicating "Ignition Lockout Fault"
Has done this once before, and "self remedied".
Thanks
Re: Atwood/Hydro Flame 8525-IV-DCLP Furnace Bob 1-15-06  
Thanks Joe, it is still under warranty, I was trying to keep from taking it to a dealer, but it looks like I will have to, trial and error parts is a little to expensive..........Bob
Re: Atwood/Hydro Flame 8525-IV-DCLP Furnace Bob 1-13-06  
All controls except sail switch and limit switch are on the circuit board. I believe it to be blower relay, but that is own the circuit board as well..........Thank you....Bob

Try checking the high limit control, this switch tells the blower to shut down.
Re: Atwood/Hydro Flame 8525-IV-DCLP Furnace jeff 11-23-09  
Can here the igniter firing and sometimes the burner ignites but cuts off as soon as the igniter stops firing?
Re: Atwood/Hydro Flame 8525-IV-DCLP Furnace Joe 1-14-06  
There have been countless problems with the climate control center. I would think the unit is still under warranty so you may get some help that way.

I have a Atwood/Hydro Flame 8525-IV-DCLP Furnace in my 2001 Fleetwood MH and when it comes on the blower squeels and makes a lot of racket but then quietes down and runs fine. Do you know of any lube points on the unit? I will bring you out of a sound sleep at three in the morning.
Thanks

Cannot get furnace to come on at all. NO blower, nothing. Thermostat is magnetic strip type and seems to be working ok. Just seems that there is no power to furnace. Checked on off switch- nothing.

I have an 2001 Atwood 8525-iv furnace in my trailer. It has started to not ignite the first time I turn it on. The fan starts normally and I hear the igniter and one time out of 3 or 4 times it will ignite otherwise it goes through three attempts to ignite and then the fan just runs continuously with no heat. I can hear it actually ignite for a couple of seconds on the first try. I have checked the pressure at the regulator and it is normal. I noticed on a couple of attempts when plugged into power that it did lite on first try but then again it will also go thru the 3 attempts with plug in power too. Is it the board or something else? Thank you

Sirs, My furnace seems to function well in the 2005 coachman I recently bought with the exception of the basic heater's been lit after a long unuse. It's in a box under the sofa with no access door. I'd like to obtain as much info on this unit as is available to make sure all is well & safe.

I have a 2008 Sunset Creek with an Atwood 8525 IV DCLP. After 1 trouble-free season, it is igniting for 5 seconds, burner goes out, does this 3 times until LED indicates ignition lockout. Have cleaned connector contacts, inspected burn chamber, and could try jumping sail switch/limit switch circuit, but ask before doing. No obvious defects on circuit board, and sometimes the problem self remedies, but recurs in days or a week of operation. Not sure my effort is remedy, and problem is consistaent as to recurrence. Suggestions?

I have a 8525 IV DCLP in my camper. When I try to start the furnace it kicks the 10 amp relay on the motor. Nothing works. Can you help? The thermostat seems to be working and something clicks in the box below the roof mount AC. TKU
Re: Atwood/Hydro Flame 8525-IV-DCLP Furnace Jim Keeton 1-19-11  
I need information for the Atwood 8525 IV DCLP the "specsheet" says is installed in my 2005 coachmen camper. It seems to function well other than the just fired up smell. It is in a box under the sofa w/no door etc. Owner/operation manual would help to be sure unit is safe and correct.
Re: Atwood/Hydro Flame 8525-IV-DCLP Furnace Tom Carmichael 10-12-06  
I have a 8525-IV-DCLP and it will lite when the trailer is hooked to 120v genaretor or power supply, but when running on the battery alone it will not lite. The blower starts and runs and you can hear it trying to start but no ignition. An help out there?
Re: Atwood/Hydro Flame 8525-IV-DCLP Furnace Jeff Peterman 12-27-11  
Unscrupulous used RV dealer sold me RV with furnace inop. Gave me a new Dinosaur Model U1B S (small) Spade rev. 10 board and said this will fix problem.
When I opened up furnace, old board was removed and missing. Wires were dangling.
Have a multi-pin connector, a thick red wire going to ignitor (I believe is ignitor, it goes to gas valve area), a blue wire to reset switch and then on to fan motor, a red wire to sail switch (goes to between fan and furnace blower).
This replacement board only has provision for the multi pin connector and one male spade terminal atop what I believe is a large capacitor. Where would the blue and red wires attach?
Did they give me the wrong board (I think they did)? If so do you think I could work out an exchange with one of the Dinosaur dealers? This used RV dealer would not help me at all. Horrible people.

Thank You -Jeff

I have a subject heater in an Aljo Pull Trailer. Heater worked fine until we came back from a hunting trip recently and noticed the "internal fan" (not the circulating fan) was running all the time. Finally disconnected thermostate wires and it still ran. Only way to shut it down (other than disconnect incoming power or batteries) is to disconnect red and black wires to the motor. Any thoughts
Re: Atwood/Hydro Flame 8525-IV-DCLP Furnace RICHARD SCHULLO 12-19-07  
I HAVE AN ATWOOD FURNACE, SERIES 8500 IV, MODEL 8525.
IT heats well, but when it reaches desired temperature, the fan does not shut off, it keeps on going.
Do I need a new circuit board?
Do you know how to find out the manufacturer's part number? I called Atwood, but they did not provide the info.
I would appreciate your reply.
Re: Atwood/Hydro Flame 8525-IV-DCLP Furnace tom 12-17-12

Re: Atwood/Hydro Flame 8525-IV-DCLP Furnace R. Davis 6-1-10  
I have two Atwood 8525 furnaces in my Motor Home. Both are doing the same thing. They ignite and run fine for 10 or 20 seconds and then the flame goes out. They repeat this for 3 times and then the blower just keeps running. Voltage is 25+ volts and drops very little when ignites.

I have a 8525-iv-dclp furnace in my trailer and the fan starts when the thermostate calls for heat the fan starts, but the burner does not ignite. The flash code says air flow switch. Where would I find that switch.
