Product Details

Description

This high-performance Air Pressure Proving Switch is a vital safety component for residential and commercial HVAC systems. Functioning as a draft inducer sensor, this switch monitors the airflow within the furnace or packaged unit to ensure the venting system is operating correctly before ignition occurs. If your heating system is experiencing ignition failure or intermittent shut-offs, replacing a faulty air pressure switch can restore reliable performance. Engineered for precision and thermal stability, this temperature-sensitive switch protects your equipment from improper venting of exhaust gases, ensuring a safe and efficient heating cycle. It is a common replacement part for gas-fired furnaces and packaged heating and cooling systems.
