Product Details

Description

Ensure your heating system operates safely and efficiently with this high-quality air pressure switch, designed for use with Carrier, Bryant, and Payne furnaces. This critical safety component, also referred to as an air proving switch, monitors the draft created by the inducer motor to confirm that exhaust gases are being properly vented before the ignition process begins. With a precise 0.27" WC (Water Column) set point, it detects blockages or mechanical failures in the venting system, preventing the furnace from firing under unsafe conditions. Ideal for troubleshooting furnace ignition failures or error codes related to air pressure, this durable switch provides a reliable solution for maintaining optimal HVAC performance and home safety.
