Goodman HVAC Error Code 2

Fault code 2 means the inducer end switch is open when the control board expects it to be closed during the ignition sequence. The furnace requires confirmation that the inducer motor has established adequate draft pressure before it will attempt ignition. Until the switch closes and signals proper airflow, the furnace will not proceed to light the burners. This is a safety lockout designed to protect the heat exchanger and prevent incomplete combustion.

No, you should not attempt to bypass or override this fault. The inducer end switch is part of a critical safety chain that ensures combustion gases are properly vented before ignition occurs. Running the furnace without confirmed draft pressure risks incomplete combustion and potential carbon monoxide buildup inside the home. Leave the unit in lockout until the underlying issue is diagnosed and corrected.

A reset may temporarily clear the fault and allow the furnace to attempt another ignition cycle, but if the underlying problem is still present, the furnace will detect the open switch again and return to lockout. Repeated resets without addressing the root cause can cause additional wear on the inducer motor and control board. The fault code will continue to return until the defective component or blockage is properly repaired.

Some causes of this fault are DIY-accessible, such as inspecting and reattaching a disconnected pressure switch hose or clearing a blocked exterior flue vent. However, testing the pressure switch with proper equipment, diagnosing an inducer motor, and working inside a furnace's gas and electrical components carries real risk. If you are not experienced with HVAC systems, a licensed technician is the safer and more reliable option for this repair.

Repair costs vary widely depending on the root cause. Replacing a pressure switch hose or the switch itself is typically a lower-cost repair, often in the range of $75 to $250 including labor. An inducer motor replacement is more involved and can range from $300 to $600 or more depending on the model and local labor rates. A blocked flue that only needs cleaning may fall on the lower end of that scale.
