Ensure the safety and efficiency of your heating system with this professional-grade Low Pressure Switch. Designed as a critical air proving component for HVAC systems, this switch monitors the airflow within the draft inducer to verify that the system is venting correctly before allowing ignition. A failing pressure switch is a common cause of furnace ignition failure, short-cycling, or system lockout. This replacement part detects low-pressure conditions to prevent hazardous operation, making it an essential safety sensor for commercial and residential rooftop units and furnaces. Built for precision and long-term reliability, it helps restore consistent heating performance and ensures your equipment meets necessary safety standards.
Type: Air Pressure Switch
Size: Small
Application: Used in residential and commercial HVAC units, furnaces, and rooftop heating systems to monitor draft inducer pressure and ensure proper combustion venting.
Specifications: Safety-critical air proving sensor; monitors negative pressure; integrated mounting bracket for standard furnace installations.
