Are you are saying that you have heat but the inducer never shuts off or do you not have heat & the inducer doesn't shut off.
Do you have a flashing led light visable through an inspection port on your furnace. If so, record the light sequence and compare it ti the diagnostic chart inside the furnace.
Turn off furnace power for a couple of minutes and then turn it back on. Now watch the furnace when the thermostat is turned up. The inducer motor should turn on, followed later by the hot surface igniter glowing and then the burners should ignite. Tell us what you see.
