Atwood 2334 furnace problem

[Konetchy]

Have a 2004 American Coach Tradtion front furnace gives the #4 fault code rear furnace gives #5 fault code so neither furnace works any ideas.

What does your owner's manual have to say about those fault codes?

I had the same coach for 12 years. The 2334 is a two speed furnace that can operate at either 23k btu or 34k btu and has two fan speeds.

Code 4 is a sticking sail switch, while code 5 is a faulty circuit board. Both those codes are usually pretty accurate, but I'd remove and reconnect all the wires at the circuit board. Corrosion on the contacts there can produce flaky results.


I've attached an image of the manual page with the fault codes. Or you can download the Hydroflame service manual and view it on page 13 (it's rather hidden!). It's free from Bryant RV website:
