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 verified with a meter, and the coils on the valve tested OK as well.

I can hear the igniter clicking, but don't hear anything from the valve itself. Propane tank is about 1/3 full, and the heater worked fine before. If the valve is opening, but failing to ignite, I think you would get some faint smell of propane from the exhaust port?

I pulled the burner assembly, the electrodes look good, and have about the 1/8" gap recommended.

Looking for ideas before I buy a new valve

Thanks
Steve

Piezo ignitors can click like a Western Union office and not ignite squat. So verifying would be high on my list. I believe in hammer and chisel troubleshooting. Use a long-neck barbecue lighter and put the fire right to the outlet to see if anything gets excited. I have a made in Mexico stove with piezo burners that sounds like a battalion of maracas. Ignite anything? Shirley you jest.

Love the brand name of your heater. Herb Tarlick at work... :)

There is two coils on the gas valve. You need to separate them and measure them individually. Readings should be the same.
