Just did and nothing happened
If you're referring to the circuit board I didn't notice any red light. It does have power and the green light is pulsing healthy on the blue controller valve up above.
I haven't tried the fan in the on position. I'll do that when I get home
Yes, fan turns on and runs when I turn the fan on at the thermostat
See if you can see a model
number on gas valve. Russ
Looks like it's SV9520H8034.
I took some pictures of the various pieces. Let me know if you need more.
Serial Number/Model Number
Gas Valve Model
ok, I don't have a specific place to get one. I do know there are a couple local shops in town to buy parts that I can call.
I just replaced the valve and it didn't fix it. It's still doing the same thing with the light pulsing green and happy and the furnace won't kick on.
please give me model number of fan board to check proper wiring for new valve. Russ
Hi Russ, sorry for the delay I had a pretty busy weekend. I hadn't messed with any of the fan board wiring, but your post got me to thinking that was likely the only place left.
We fortunately have two furnaces (upstairs and down) with the same board so I just swapped them between the two units. Sure enough, that was the problem and now the broke one is working perfect and the good one is now broke. I should be able to find one of these locally.The board model is ST9160B 1068
I did notice on the bad board that it was very warm in the middle behind one of the circuits and on the good one it was cold to the touch. So I suspect something popped on it.
Unfortunately I had to pretty much destroy the old gas valve to get it off, so we did spend a little extra swapping that out, but even with that you helped me save a lot of money over a standard service call, so thank you very much for your help. :)
