Amana-Goodman C6456506 Pressure Switch

The Amana-Goodman C6456506 Pressure Switch is a critical OEM replacement part engineered for high-efficiency HVAC equipment. Designed with a precise setpoint of -1.05" WC, this negative pressure sensor monitors induction fan performance and flue venting to ensure safe combustion cycles. This diaphragm-actuated switch is a direct replacement for Goodman furnace pressure switches used in many 80% and 90%+ AFUE gas furnaces. As a genuine Amana HVAC part, the C6456506 prevents ignition if the draft inducer motor fails to maintain the required static pressure, protecting the system from dangerous carbon monoxide buildup. Field technicians should verify the pressure switch rating against the factory nameplate before installation to ensure exact compatibility. Utilized across a wide range of Amana, Goodman, and Janitrol models, this switch features standard spade terminals for rapid electrical integration within the furnace control circuit.

Key Benefits for HVAC Professionals

• Accurate Setpoint Calibration: Calibrated at -1.05 inches water column to meet strict factory specifications for safety and sequencing.
• Direct OEM Compatibility: Eliminates the risks associated with universal aftermarket switches that may fail to trip at the correct negative pressure threshold.
• Enhanced Safety Logic: Restores proper HVAC pressure switch troubleshooting protocols by ensuring the draft inducer is clearing the heat exchanger effectively.
• Industrial-Grade Build: Constructed to withstand the temperature fluctuations and duty cycles common in residential and light commercial furnaces.

Common Questions

How do I know if my C6456506 pressure switch is faulty?
If your furnace or air handler codes for "Pressure Switch Open," first check for blocked vent pipes or a failing inducer motor. If those are clear and the Amana-Goodman C6456506 fails to close under the specified -1.05" WC load, the internal diaphragm or electrical contacts have likely failed.

Can I use a switch with a different WC rating?
No. Using a switch with a higher or lower WC pressure rating than the -1.05" specified can lead to unsafe combustion conditions or frequent nuisance tripping. Always match the OEM rating for the specific furnace model.

Does this switch work for both Amana and Goodman models?
Yes, this Goodman C6456506 pressure switch is a cross-compatible component used by both brands under the Daikin manufacturing umbrella, provided the part number matches your technical manual.
