Product Details

Description

This high-quality air pressure switch is a critical safety component designed for residential HVAC and furnace systems. Functioning as an air-proving switch, it monitors the draft inducer motor to ensure proper airflow and venting before allowing the heating cycle to begin. Rated at 0.18" WC (Water Column), this Single Pole Single Throw (SPST) switch detects pressure changes to prevent the burner from igniting under unsafe conditions, such as a blocked flue or a failing inducer motor. This replacement part includes a pre-attached mounting bracket for a secure and straightforward installation, making it an essential component for maintaining the efficiency and safety of your gas-fired heating equipment.
