Product Details

Description

This high-quality 0.15" WC Air Pressure Switch is an essential safety component designed for HVAC systems, including residential and commercial heating units. Often referred to as an air proving switch, this part monitors the pressure differential within your system to ensure the inducer motor or blower is providing adequate airflow for safe combustion and venting. If your HVAC unit fails to ignite or shuts down prematurely due to a pressure sensor error, replacing a faulty switch is critical for restoring reliable climate control. This durable component is engineered to detect precise air pressure levels, preventing the system from operating under hazardous conditions such as blocked flues or motor failure.
