Description
This furnace air pressure switch is a vital safety component used to verify proper airflow and draft within gas-fired heating systems. It monitors pressure created by the inducer motor and allows the furnace to proceed with ignition only when safe venting conditions are met. Accurate and dependable, this pressure switch helps protect the furnace from unsafe operation by interrupting the heating cycle if adequate airflow is not detected. Replacing a faulty pressure switch can resolve issues such as ignition failure, short cycling, or pressure-related fault codes.
