Heil Gas Furnace Not Lighting
No heat yet....I blew out the 1/2-inch condensate hose between the two condensation collector units (top and bottom), including the drain hose from the lower unit which flows to the clear drain hose outside the furnace. Still have two LED flashes (repeatedly), and I can hear a humming sound from the mother board behind the lower access panel. Is there a reset button on the board? Or, is the smaller motor/fan near the heat exchanger froze into position? (Sorry, I didn't answer sooner; I was out of town for five days). Again, thanks for everyone's help...
