Amana-Goodman 10727905 Pressure Switch

The Amana-Goodman 10727905 Pressure Switch represents a critical safety and operational component for your HVAC service calls. As a factory-certified HVAC replacement part, this SPST pressure switch is engineered to monitor the negative pressure created by the inducer motor, ensuring proper venting before the ignition sequence begins. It features a precise -1.10" WC set point, making it a drop-in OEM furnace pressure switch for specific Goodman, Amana, and Janitrol models. When you are troubleshooting a furnace that is failing to stay in a heat cycle or displaying a 3-flash error code, this switch provides the reliable electrical contact closure needed to verify draft integrity. Constructed for the high-cycle demands of residential gas furnaces, the Goodman 10727905 ensures your installs maintain factory specifications for flue gas management and combustion safety.

• Precise Draft Detection: Factory-set at -1.10" WC to ensure the inducer motor is moving sufficient air for safe combustion.
• OEM Compatibility: Genuine Goodman Amana replacement part designed for perfect fitment in gas furnace pressure switch applications.
• Reliable Logic: Single-pole, single-throw (SPST) configuration integrates seamlessly with standard furnace control boards.
• Pre-Tested Quality: Each unit is verified by the manufacturer to meet strict performance tolerances before leaving the factory.

• How do I know if the 10727905 switch is the source of the furnace failure? Use a manometer to verify that the inducer is pulling at least -1.10" WC. If the pressure is sufficient but the switch remains open (infinite resistance), the internal diaphragm or contacts have likely failed.
• Does this switch come with new tubing? This is the individual pressure switch component. We recommend inspecting existing vacuum lines for cracks, moisture, or debris that could affect the switch's operation.
• Can I use this to replace a switch with a different WC rating? No. Pressure switches are safety devices calibrated to specific blower and venting requirements; always match the -1.10" WC rating exactly to maintain equipment safety.
