The GOODMAN 0130F00478 Dual Pressure Switch is designed for Goodman Amana Janitrol furnaces equipped with pressure ignition systems. It features dual pressure monitoring and adopts mechanical operation with durable plastic and metal construction to ensure stable pressure sensing. The switch monitors both high and low furnace pressure, automatically triggering protection when pressure is abnormal to prevent system damage.
This dual pressure switch resolves common problems caused by faulty switches, including high/low pressure abnormalities, inducer motor errors, ignition failure and frequent shutdowns, restoring stable furnace operation.
