Nordyne 632555 Pressure Switch
The Nordyne 632555 Pressure Switch is a critical dual-stage safety component engineered for high-efficiency gas furnaces and packaged units. As a genuine OEM HVAC replacement part, this switch monitors the negative pressure generated by the draft inducer motor, ensuring the flue is clear and combustion gases are safely exhausted before the ignition sequence begins. Designed to replace or cross-reference with Nordyne 632555R, this component is calibrated for precise set points (often rated at -0.70" and -0.50" W.C. depending on the specific application), providing the exact tolerances required by Intertherm, Miller, following and Frigidaire gas furnaces.
For service technicians, the Nordyne 632555 is a direct-fit solution that eliminates the reliability risks associated with universal aftermarket switches. It features a robust diaphragm construction and high-quality electrical contacts to prevent common "limit switch open" or "pressure switch stuck open" fault codes. This OEM part ensures the furnace inducer motor and venting system maintain proper static pressure, protecting the heat exchanger from overheating and preventing carbon monoxide fallback into the residential space.
Key Benefits:- Genuine Nordyne OEM Quality: Guarantees specific pressure calibrations and electrical compatibility for Nordyne-manufactured heating systems.
- Enhanced System Safety: Prevents the gas valve from opening if insufficient draft or blocked flue vents are detected.
- Reliable Ignition Cycles: Minimizes "short cycling" and "no heat" calls by maintaining consistent pressure switch closed status during operation.
- Broad Compatibility: Fits a wide range of mobile home and residential brands including Tappan, Westinghouse, and Maytag HVAC units.
- What does a 'Pressure Switch Open' fault code mean? Usually, this indicates the inducer motor is running but the 632555 switch hasn't sensed enough vacuum. This can be caused by a cracked pressure hose, a blocked chimney, or a failing switch diaphragm.
- Is this switch a direct replacement for the Nordyne 632555R? Yes, the "R" suffix typically denotes a retail or updated part number, but the technical specifications and fitment remain identical for the 632555.
- Will this fix a furnace where the inducer runs but the igniter won't glow? Often, yes. If the pressure switch fails to close, the control board will lock out the ignition sequence as a safety precaution.
