Lennox WhisperHeat G20Q3/4E-100-5 Gas Furnace - Sparks But No Flame

I have a Lennox WhisperHeat G20Q3/4E-100-5 Gas Furnace which will not ignite.

When turned on, it clicks repeatedly for about a minute or so with the green led light steady on, then it stops clicking and the green led light goes off. The led never flashes; it's just steady on when clicking, steady off when not.

With each click, I see a spark between the ignitor and the pilot nozzle, but never any flame.

I would think that with gas coming through the nozzle for a minute but not being burned, I'd smell some gas. But I do not smell gas at all, so I wonder if no gas is getting through.

The gas valve is a Honeywell VR8204H.

Any suggestions on next steps?

Are you getting 24 volts AC to the valve?

Hi Houston24,

How do I check whether I have 24 volts to the valve? I have a multimeter but not sure how to check that.

Thanks,

Greg
