How much does it cost to replace a furnace inducer motor?
A draft inducer motor costs $200 to $1,500 to repair or replace. A simple fan wheel might cost $20 in parts with another two hours in labor. Replacing the entire unit runs $600 to $1,500, depending on the model and brand.

What should I do if my furnace inducer fan wont ignite?
After the hot surface ignitor heats up for 30 seconds or so, the circuit board should turn on the main burner gas and the main burners should light off the HSI. You need to check to see if the HSI is burned out.

Which is better an induced draft furnace or a standing pilot furnace?
This system is more reliable and safer than old conventional furnaces, which relied on a natural draft coming in from an opening at the front of the furnace. Induced draft furnaces use either an intermittent pilot (IP) or hot surface ignition (HSI) instead of a standing pilot light.
