The Goodman 0130F00506 is a genuine OEM air pressure switch for the Amana/Goodman AMES800804CXAA gas furnace. Rated at -0.75 inch water column and normally open, this switch proves that the induced-draft blower is running and that the venting is unobstructed before the control board allows ignition. If adequate negative pressure isn't sensed, the furnace safely refuses to fire, preventing operation with a blocked flue.
Pressure switches must match the furnace's exact set point and NO/NC configuration; a -0.75" WC switch cannot be substituted with a different rating without risking no-ignition faults or unsafe operation. Genuine OEM guarantees the correct pressure calibration and hose port. We recommend OEM for this safety-linked part.
Easy (2/5). Disconnect power, note the hose and wire positions, remove the mounting screws, and transfer the tubing and terminals to the new switch. About 15–20 minutes. Confirm the hose is free of condensate and seated fully.
