Amana-Goodman C6456513 Pressure Switch

The Amana-Goodman C6456513 Pressure Switch is a critical OEM replacement part designed for specific Goodman and Amana furnace models. This single-pole single-throw (SPST) inductive switch is factory-calibrated to a set point of -0.65" WC, ensuring precise monitoring of the flue gas pressure and draft inducer performance. If the static pressure falls outside the safe operating range, the switch breaks the electrical circuit to the gas valve, preventing unsafe combustion cycles. The C6456513 pressure switch serves as the direct cross-reference for the C6456504, offering seamless integration with existing control boards and wiring harnesses. Built for high-cycle reliability, this switch maintains system safety by verifying proper venting before allowing ignition. For technicians troubleshooting furnace pressure switch failure or induced draft blower issues, using this genuine Goodman draft switch ensures the unit operates according to original equipment manufacturer specifications for pressure differential and airflow safety.

Key Benefits

• Direct OEM replacement ensures exact electrical ratings and mechanical fitment for Goodman and Amana equipment.
• Internal SPST contact configuration designed for standard 24V control circuits in high-efficiency gas furnaces.
• Calibrated -0.65" WC set point provides accurate sensing of negative pressure created by the inducer motor.
• Replaces legacy part number C6456504, allowing for a simplified inventory and direct compatibility with older systems.
• Durable phenolic housing resists heat and vibration found within the burner cabinet.

Common Questions

Is the C6456513 compatible with my Goodman furnace?
This switch is compatible with various Amana and Goodman models requiring a -0.65" WC rating. Use the model number from your furnace data plate to verify compatibility, as many units utilize multiple switches with different set points.

What does it mean if my furnace is stuck in a pressure switch lockout?
A lockout often indicates either a faulty C6456513 pressure switch, a restricted flue, a failing inducer motor, or obstructed pressure tubing. Verify the actual static pressure with a manometer before replacing the component.

Can I use a universal pressure switch instead of this OEM part?
While universal switches exist, OEM Goodman parts are recommended to ensure the set point and sensing characteristics match the safety parameters established by the manufacturer's engineering team.
