Atwood 2334 DCLP

Again Thank for all your help. Great information. This should work out great. Gary

Fan speed and which gas valve is used are critical

Low fan and high btu gas valve.........Smoking/Sooting (as you are aware)
High fan and low btu gas valve.........Lean/HOT flame (if it lit/stayed lit) overfiring..furnace trip

White wire (6 pin connector on Speed control board----#6 position) is 10V power to motor for Low Speed (RED wire thru the power switch/circuit breaker is fan 12V high speed)

Low but gas valve....Brown wire is power (6 pin connector on speed control board----position #1)

High btu gas valves.....Red wire is power (6 pin connector on IGNITION board----position #4) Only Pins 1,3 & 4 are used

Hey OB, just a after-though, would there be a simple way to make this a one speed unit by moving wires around? I have not had time to get back with my friend to check out the board. Will see what he wants to do tomorrow. Thanks again Gary

Thanks OB Your information was useful. Gave me something to work on. Now I have to figure out why the board is not changing the gas valves. Thanks Gary

Atwood 2334 DCLP........is a 2 stage DC operated furnace using LP fuel

It has 2 gas valves....23K btu and a 34K btu
Fan motor is also 2 speed..high speed for higher btu gas valve (34K btu) and low speed for the lower btu gas valve (23K btu)

Speed control module is NOT swapping gas valves when fan speed swaps thus the smoking----low air to fuel ratio
