Laars Heating Systems E2312300 Pressure Switch
Professional-grade Laars Heating Systems E2312300 Pressure Switch is a critical safety component designed for precise draft monitoring in high-efficiency boilers and volume water heaters. This 0.15"WC pressure switch functions as a normally open contact that closes once the inducer motor establishes the required static pressure, ensuring the combustion chamber is properly vented before the ignition sequence begins. Built to handle the rigorous duty cycles of commercial and residential hydronic systems, this OEM Laars replacement part prevents the main gas valve from opening if venting is obstructed or the inducer fails, mitigating the risk of flue gas spillage.
When troubleshooting Laars boiler parts, a failing switch often manifests as a "pressure switch open" error code (such as Error 137 or 67 on specific models) or a system that hangs after the blower initiates but before the igniter glows. The E2312300 features a factory-calibrated set point of .15 inches water column, providing the exact sensitivity required for low-pressure draft sensing. Using a genuine Laars E2312300 ensures seamless electrical compatibility with the existing wiring harness and maintains the factory-specified safety parameters of your heating appliance.
Key Benefits:- Precise Calibration: Fixed 0.15"WC set point ensures accurate detection of proper venting pressure for safe ignition.
- System Protection: Acts as a primary safety interlock to prevent combustion during inducer failure or flue blockages.
- OEM Compatibility: Designed specifically for Laars equipment, including select NeoTherm and Rheos+ models, ensuring correct mounting and vacuum port alignment.
- Durable Construction: Engineered to withstand the heat and moisture levels common in high-efficiency condensing boiler cabinets.
- How do I know if the E2312300 is faulty? Use a multimeter to check for continuity across the terminals. If the switch remains open while the inducer is running and the venting is clear, it likely needs replacement.
- Can I use a universal switch instead? Universal switches often lack the exact .15"WC calibration, which can lead to nuisance lockouts or unsafe operation. Sticking with the Laars E2312300 is recommended for reliability.
- What causes these switches to fail? Common culprits include moisture in the sensing tube, cracked diaphragms, or debris entering the vacuum port from the inducer housing.
