Default Furnace heat cycle

If the inducer was the problem, it should not get to the igniter stage. I'm
wondering if the igniter isn't drawing enough amps to satisfy the board.

You're saying maybe the heat sensor has crud from previous cycles
and shuts the gas valve down before the burners have a chance to
fire???

The burners don't fire and then shut down prematurely. They
fail to fire at all.

Hi,
When inducer motor comes upto speed pressure switch should trigger next
is ignitor coming on(if it's not spark type, it should glow bright) then
valve opens, gas ignites, flame sensed, blower comes on. What model
furnace? No trouble code?
