Product Details

Description

The York Pressure Switch is a critical safety component designed for high-efficiency HVAC systems and residential furnaces. This air-proving switch precisely monitors the pressure differential within the combustion chamber to ensure the inducer fan is operating at the correct velocity. By verifying that harmful exhaust gases are being properly vented, this switch allows the ignition sequence to proceed safely. Rated at -0.45" WC, it serves as a vital sensor that prevents the furnace from firing if a venting obstruction or mechanical failure is detected. If your heating system is failing to ignite or shuts off prematurely, a reliable replacement air pressure switch is essential for restoring peak performance and ensuring home safety. This durable component is engineered for precision and long-term reliability in forced-air heating applications.
