Product Details

Description

The Connector Pressure Switch is a critical safety component designed for modern HVAC heating systems. As an air proving switch, its primary function is to monitor the pressure levels within the draft inducer assembly, ensuring that the venting system is clear and the motor is moving enough air for safe combustion. If the switch detects an airflow obstruction or mechanical failure, it signals the furnace to halt the ignition process, preventing the buildup of hazardous gases. This high-quality replacement part is essential for restoring the reliability of your heating unit when the original sensor fails to respond. It is built to withstand the rigorous temperature cycles of residential furnaces, providing long-lasting performance and peace of mind during the heating season.
