Reznor 204326 Pressure Switch
The Reznor 204326 Pressure Switch is a mission-critical safety component designed for heavy-duty HVACR applications, specifically within Reznor unit heaters and combustion air systems. This SPDT pressure switch features a precise 0.7" WC (water column) set point, ensuring accurate monitoring of the pressure differential required for safe burner ignition and operation. Built with a dual 1/4" barb connection, it integrates seamlessly into standard pneumatic tubing layouts, providing a robust interface for combustion air pressure sensing. As an OEM-spec HVAC replacement part, it is engineered to replace failing sensors that cause ignition sequence interruptions or limit switch trips. By utilizing a Single Pole Double Throw configuration, this switch offers versatile wiring options for both normally open and normally closed circuits, ensuring reliable system feedback and protecting high-value heat exchangers from improper venting conditions. When diagnosing "no-heat" calls, verifying the 0.70" WC trip point of the Reznor 204326 is essential for maintaining strict industrial performance standards.
Key Benefits- Precise Calibration: Factory-set at 0.7" WC to maintain optimal combustion safety and prevent pilot or burner failure.
- Industrial Compatibility: Features dual 1/4" barb connections for easy fitment with standard sensing lines and silicone tubing.
- Versatile Electrical Interface: The SPDT (Single Pole Double Throw) design allows for flexible integration into various localized control circuits.
- OEM Reliability: Designed specifically as an OEM Reznor pressure switch to ensure exact drop-in compatibility and electrical match for unit heaters.
What are the signs that my pressure switch has failed?
Common indicators include the inducer motor running without the burner igniting, or the control board flashing a code for "Pressure Switch Stuck Open." Professionals should check lines for moisture or cracks before replacing the Reznor 204326.
Can I use a higher set point switch instead of the 0.70" WC version?
No. Pressure switch ratings are specific to the appliance's blower performance and venting length. Using a switch with a different water column rating will compromise safety and cause intermittent operation.
Does this switch handle both positive and negative pressure?
Yes, the dual 1/4" barb configuration allows the switch to monitor the differential between two points or a single point relative to atmospheric pressure.
