Product Details

Description

This air pressure switch is a critical safety component designed for Goodman, Amana, and Janitrol gas furnaces. Often referred to as an air proving switch, its primary function is to monitor the pressure produced by the draft inducer motor to ensure exhaust gases are being properly vented. Rated at -0.55" WC, this switch acts as a safeguard, preventing the furnace from igniting if it detects an obstruction in the flue or a failure in the venting system. If your heating system is experiencing ignition issues or intermittent shut-offs, this replacement pressure sensor provides a reliable solution for restoring safe and efficient furnace operation.
