Trane SWT3073 Furnace Air Pressure Switch – SPDT Safety Switch (.76" Set Point)

The Trane SWT3073 Pressure Switch is a genuine replacement part designed to ensure safe and reliable operation of gas-fired heating systems. This SPDT (Single Pole Double Throw) air pressure switch monitors inducer motor airflow and verifies proper draft before allowing the furnace to ignite, preventing unsafe operation and protecting your heating system.

Engineered for accuracy and dependability, the SWT3073 interrupts the heating cycle if adequate airflow is not detected, safeguarding the furnace from potential damage. Replacing a faulty pressure switch can resolve issues such as ignition failure, short cycling, or pressure-related fault codes.
