Laars Heating Systems E2074501 Pressure Switch

Laars Heating Systems E2074501 Pressure Switch

The Laars Heating Systems E2074501 Pressure Switch is a high-precision safety component designed for critical pressure monitoring in residential and commercial hydronic systems. This 0.3" WC pressure switch features a Single Pole Single Throw (SPST) configuration, engineered to ensure proper inducer fan operation and venting before allowing the ignition sequence to proceed. Built with a robust 1/4" barb connection, this switch provides a secure pneumatic link to the burner or collector box, eliminating nuisance trips caused by minor pressure fluctuations. It is specifically calibrated for low-pressure applications, maintaining tight tolerances to protect the heat exchanger from poor combustion conditions. Ideal for Laars Mini-Therm JVi and JVH series boilers, this OEM part is rated for operation up to 5,000 feet, making it a reliable choice for high-altitude installs. When diagnosing a furnace pressure switch stuck open error or "no heat" calls, this direct replacement HVAC pressure switch ensures the system meets exact manufacturer specifications for airflow verification.

Key Benefits
  • Precise 0.3" WC Actuation: Calibrated specifically for Laars boiler draft requirements to ensure consistent safety shut-off.
  • OEM Compatibility: Designed for seamless integration with Laars JVH075, JVS050, and Mini-Therm units.
  • Durable Barb Fittings: The 1/4" barb connection ensures a leak-resistant seal for long-term pneumatic stability.
  • SPST Electrical Logic: Simple single-pole configuration allows for straightforward integration into the 24V control circuit.
Common Questions

Is this switch compatible with high-altitude boiler installations?
Yes, the E2074501 is engineered and rated for performance in systems located at altitudes ranging from 0 to 5,000 feet.

What does it mean if my pressure switch is "stuck open"?
An "open" switch usually informs the control board that either the inducer isn't creating enough draft or the pneumatic tubing is clogged. Replacing a faulty switch restoration of the safety circuit logic.

Can I use this switch in place of a 0.5" WC model?
No, pressure switches must match the manufacturer's specified set point (0.3" WC) to ensure the boiler operates within its certified safety and combustion parameters.
