Amana-Goodman 10207903 Pressure Switch

The Amana-Goodman 10207903 Pressure Switch is a critical safety component designed for precise furnace pressure switch monitoring in high-efficiency gas furnaces. Rated at -1.20" WC (Water Column), this SPST induction draft pressure switch ensures the combustion blower is pulling the correct amount of air through the heat exchanger before ignition. It features a Single-Pole Single-Throw (SPST) contact configuration, engineered to close upon reaching the specified vacuum pull, maintaining strict system safety protocols. As a direct OEM replacement pressure switch, it is compatible with a wide range of Goodman and Amana 90% AFUE units, providing a drop-in solution for HVAC pressure switch troubleshooting. The 10207903 is built for durability in harsh environments, ensuring reliable gas furnace inducer motor feedback and preventing short-cycling or ignition failure caused by improper venting or restricted airflow.

• Factory Calibrated: Set at -1.20" WC for precise vacuum detection and system safety.
• OEM Compatibility: Designed specifically for Goodman and Amana furnace repair, ensuring exact fit and electrical specifications.
• SPST Configuration: Normally open contacts close on pressure drop to signal valid combustion conditions.
• Hardware Resilience: Engineered to withstand high temperatures and vibration common in furnace inducer assemblies.

Common Questions

How do I verify if the 10207903 is the correct switch for my furnace?
Verify the WC rating on your existing switch. The 10207903 is rated for -1.20" WC. Using a switch with an incorrect pressure rating can lead to safety hazards or system lockouts.

What causes this pressure switch to trip?
While a faulty switch can occur, trips are often caused by restricted vent pipes, a failing inducer motor, or moisture in the vacuum tubing. Always check the venting and collector box before replacing the component.

Can I use an adjustable pressure switch instead of this OEM part?
Technicians recommend using the OEM 10207903 to ensure the furnace operates within the manufacturer's exact combustion parameters and safety standards.
