Hydroflame Furnace
I have a hydroflame 8900 II furnace in my RV, which will not ignite. Does anyone know a way to verify the gas valve is opening? The led on the circuit board indicates power to the valve, which I verif...

Well, I pulled the burner assy out again, and the orifice seems to be clear. Also applied 12V to gas valve, and it appears to operating as it should.
I also verified the electrode is working properly, yet still not firing. Yesterday, I checked the lead to the valve with a multi meter, and it appeared to send voltage, but the reading was erratic. Thought maybe the contact on the meter wasn't secure.
The sequence of operation says the sail and limit switched need to be working properly to sent power to the ignition board. I checked voltage at the board and it was 12.4V. The lead to the gas valve from the circuit board travels via some device I'm not sure what it is.
On some models an on/off switch is in this location, but not on the 8900-II. I cannot find any kind of switch anywhere, and as I said, the furnace worked fine before.
Any thoughts on the unknown device/switch? I'm thinking of by-passing it to see the results.
