Amana-Goodman 20197310 Pressure Switch

The Amana-Goodman 20197310 Pressure Switch is a critical induced draft safety component engineered for Amana, Goodman, and Janitrol gas furnaces. This Single Pole Single Throw (SPST) switch is factory-calibrated to a -0.60" PF (Pressure Fall) setpoint, ensuring the inducer fan maintains the precise vacuum required for safe combustion and flue gas venting. Featuring a 1/4" barbed connection for secure pneumatic tubing attachment and standard 1/4" spade terminals, this switch provides a direct-fit replacement for the 9371VO-HS-0015. It serves as a primary limit against vent blockages or blower failure, preventing the ignition sequence if the combustion air-flow pressure is inadequate. For contractors, the Goodman 20197310 is a high-reliability OEM part that resolves furnace pressure switch lockout codes and 7-flash error codes on compatible control boards, maintaining the integrity of the induced draft system without requiring field adjustments.

• OEM Compatibility: Exact replacement for Amana and Goodman furnace models including AMH95, GMS9, and GMH95 series.
• Precise Sensing: -0.60" W.C. rating ensures accurate detection of negative pressure within the collector box.
• Fast Installation: Integrated mounting bracket and 1/4" barbed hose port facilitate rapid swap-outs during service calls.
• Safety Compliance: Designed as a normally open SPST switch that closes only when the draft inducer motor reaches the proper RPM.

How do I troubleshoot a 20197310 switch that won't close?
First, verify 24V at the incoming terminal. If the inducer motor is running, use a manometer to confirm the vacuum pressure exceeds -0.60" W.C. If the pressure is correct but the switch stays open, the internal diaphragm may be ruptured.

What causes a "Pressure Switch Stuck Open" error code?
This is often caused by a blocked flue pipe, a clogged port on the collector box, or water in the pressure switch tubing. Always clear the lines before replacing the hardware.

Can I use this switch as a universal replacement?
No. Pressure switches must match the manufacturer's specified W.C. rating exactly. Using a switch with the wrong setpoint can lead to dangerous combustion conditions or nuisance tripping.
