Draft Inducer Motor for your furnace

Is your furnace not starting up and maybe making a funny sound like it is trying to start up?  Perhaps you have shut it off and then turned back on. Maybe you just turned the fan on and it works.  You may be in need of a new induced draft motor or draft inducer motor. This motor is what creates a draft through the heat exchanger. Air and gas are drawn through the front of the furnace and conveyed to the flue connector. What you have is a whole assembly. In most cases the entire assembly is what gets replaced. In some rare cases you can replace just the motor which is cheaper but takes longer to do. When replacing the assembly it is important to replace the gasket that goes between the assembly and the heat exchanger manifold. The gasket is usually fiberglass or fire rated foam. Modern furnaces have this motor as well the circulating or blower motor. Out of the 2 motors, the inducer motor typically is the one that fails first. The bearings start to wear out making the operation noisier and eventually they fail and the motor stops turning. I have seen motors with noisy bearings run for a long time (years) and in other cases no increased noise is noticed before the motor fails.

The induced draft assembly is typically made of steel or metals such as the one in the picture.

They often  develop rust and wear out. Replacing the draft inducer motor assembly is the only way your furnace will operate.
