Goodman 0130F00436S Pressure Switch -.72/-1.47 W.C.

Description

The Goodman 0130F00436S is an OEM replacement pressure switch designed for use in Goodman and Amana gas furnaces and air handlers. This dual-setpoint pressure switch monitors negative pressure generated by the inducer motor to verify proper draft and venting operation before allowing the furnace to proceed through the ignition sequence — a critical safety function that protects against unsafe combustion conditions.

How It Works

The pressure switch is a normally open (NO) safety device that closes when the inducer motor creates sufficient negative pressure in the flue system. If adequate draft pressure is not established or is lost during operation, the switch opens and interrupts the control board signal, locking out the ignition sequence to prevent unburned gas accumulation and potential hazards.
