Bad Armstrong circuit board?
Hello,
I have an Armstrong Ultra SX 80 Model #GUJ075D10-3A. My circuit board numbers on it says FCC-1A 40403001 then 9807 below. The R-1 sensor is burnt on both sides and I believe this is my problem. I want to replace the board myself but I don't know what board I should get to replace it with. I'm not a H/C guy and I am confused and I'm not cross referencing it right or something. Some sites say replace it with part #40403003 at $134 and another site it says code # CIB9120C2028 at $188. Both pics look like different boards. My model number doesn't really match exactly with perfect. I just don't want to get the wrong one. Any help would be greatly appreciated. Thanks |

My light doesn't not come on the circuit board 50a50-241 I have 120volts coming into the board but furnace won't do anything at all. Transformer has power on both sides. I have 24 volts when I check R and W on the board. I think it is a bad board would you agree?
