Having a problem with a Haier HGA080N3H, inducer motor turns on but will not light. Inducer fan stays on even thuogh the furnace does not light. Any comments would be greatly appreciated.

After the inducer starts, you should have some form of burner ignition happen. It could be a glowing hot surface ignitor or a pilot flame. If there is no sign of any main burner ignition, then you most likely have an inducer pressure safety switch that's open. Either the inducer is not generating the correct pressure or there is an obstruction in the flue or the tubing from the inducer assembly to the pressure switch is clogged.
