Amana-Goodman 20197313 Pressure Switch

The Amana-Goodman 20197313 Pressure Switch is the direct OEM replacement for the legacy 20197306 model, engineered to maintain precise safety parameters in high-efficiency gas furnaces. As a veteran-grade furnace pressure switch, it is factory-calibrated to a -.37" WC (water column) set point, ensuring the inducer motor generates sufficient negative pressure before the ignition sequence initiates. This SPST (Single Pole Single Throw) air switch serves as a critical safety limit, monitoring the combustion air blower to protect against venting obstructions or mechanical failure of the draft inducer.

Designed for compatibility with a wide range of Amana, Goodman, and Janitrol cabinet configurations, this genuine OEM part (alternate part number 9371VO-HS-0013) eliminates the diagnostic guesswork of universal replacements. Its robust plastic housing resists heat cycles and prevents diaphragm fatigue, providing a reliable electrical path for the 24V control circuit once the specified vacuum range is achieved.

• Precise Calibration: Fixed at -.37" WC to meet specific manufacturer airflow requirements for safe flue gas venting.
• Direct Replacement: Seamlessly replaces legacy part 20197306 with the same footprint and SPST logic.
• Enhanced Safety: Acts as a primary safety interlock, preventing gas valve operation if venting conditions are unsafe.
• Durability: High-grade internal diaphragm designed to handle the frequent cycling of modern high-efficiency HVAC units.

• Will the 20197313 replace my metal-cased 20197306? Yes, this plastic-cased version is the current manufacturer-approved update for older metallic 20197306 switches.
• What does a -.37" WC rating mean? This is the specific negative pressure required for the switch to close. If your manometer shows a lower vacuum, the furnace will not fire.
• Does this switch work on 2-stage furnaces? This specific model is typically used as a single-stage or low-fire switch depending on the furnace wiring diagram.
