This genuine OEM Goodman 20197308 pressure switch is a direct-fit replacement for the AMVM961005DXAA modulating variable-speed gas furnace, along with many other Goodman and Amana furnace models that share the same platform. The switch monitors combustion-air and venting draft, closing on a proof of proper airflow and locking out ignition if a blocked flue, failed inducer, or restricted intake is detected. A faulty pressure switch is one of the most common causes of a furnace that clicks but will not light.
Our genuine OEM switch is calibrated to the exact -.10" WC set point specified by the manufacturer, ensuring correct lockout behavior and safe combustion. Universal or generic switches often ship with a nearby-but-not-exact trip point, which can cause nuisance lockouts or, worse, mask a real venting fault. For a safety-critical component we recommend the OEM part.
Moderate. Requires disconnecting power, removing the old switch, and transferring the pressure tubing to the correct port. Most experienced DIYers complete it in 20–30 minutes; if you are unsure which port the hose attaches to, consult a licensed HVAC technician.
