I have a Olsen Duomatic gas furnace with a Honeywell igniter board and Honeywell gas valve set up to be a downflow furnace. The old inducer motor died so bought new one with exact same specs. Also replaced the Inducer Relay; ignitor board, spark ignitor. Now when power is turned ON the inducer motor does not start but ignitor lights pilot, then gas comes on, burners light...and flame blowback happens - all w/o inducer motor making a sound of life. Connections from inducer have been checked and are in right place. what is going on here? Inducer should fire up at start before anything else happens!
