Laars Heating Systems RE2334700 Pressure Switch
The Laars RE2334700 Air Pressure Switch is a critical safety component engineered specifically for the Laars NeoTherm boiler series, including models NTH-150 through NTH-850. As a veteran-grade HVAC replacement part, this switch monitors the differential pressure within the combustion chamber, ensuring that the inducer fan is moving sufficient air for safe combustion. If the boiler pressure switch detects a blocked vent, intake obstruction, or fan failure, it immediately opens the safety circuit to prevent the accumulation of carbon monoxide and protect the heat exchanger from thermal stress. This OEM part features a precise setpoint calibration and a durable diaphragm assembly designed to withstand the high-cycle demands of condensing boiler applications. For technicians performing boiler troubleshooting, replacing a fluttering or stuck switch with this genuine Laars Heating Systems component restores the sequence of operation and ensures the unit meets its original energy-efficient heating specifications. Its compact design and standard spade terminals allow for a direct-drop-in fit, minimizing labor time during emergency service calls.
Key Benefits- Direct OEM Compatibility: Engineered for the full range of Laars NeoTherm high-efficiency boilers (NTH-150, 285, 500, 600, 850).
- Failsafe Combustion Monitoring: Prevents ignition if airflow pressure is insufficient, protecting the system and the property.
- Industrial-Grade Construction: Built with robust materials to resist moisture and high ambient temperatures in mechanical rooms.
- Optimized Performance: Maintains the differential pressure thresholds required for clean, low-emission combustion.
- What are the signs of a failing pressure switch in a NeoTherm boiler? Common indicators include a lockout with a "pressure switch did not close" fault code, the inducer fan running without ignition, or intermittent cycling during high-wind conditions.
- Can this switch be used in other Laars models? While primarily for the NeoTherm series (NTH/NHT), always verify the specific part number in your technical manual, as setpoints vary by HVAC equipment BTU ratings.
- How do I test the RE2334700 during a service call? Use a manometer to check the actual pressure at the switch ports and a multimeter to verify continuity across the terminals once the setpoint is reached.
