How to Troubleshoot a Goodman Draft Inducer
The draft inducer blower on a Goodman furnace is meant to help blow the gases that are generated during combustion up and through the furnace and out the chimney. The draft inducer is located inside the blower access compartment and has a motor and a fan assembly. If the draft inducer is not working properly, the furnace may not operate efficiently, soot may develop on the burners, or the furnace may shut down as a safety precaution to prevent dangerous gases from leaking. Does this Spark an idea?

1
Shut off power to your Goodman furnace at the household breaker panel and wait for the furnace to cool down completely before proceeding. Stop immediately if you smell gas, leave the home then call your gas company or local emergency services.

2
Check the flue and vents in the furnace and clear away anything that may obstruct proper airflow. Debris can trip the pressure switch circuit and the blower motor, which will cause the furnace to lock out.
