The Goodman 0130F00000P is a genuine OEM air pressure switch calibrated to -1.10 inches of water column and identified by its Sun Gold housing. It is engineered for the GMH950453BXAF 96% AFUE gas furnace and related Goodman/Amana models. This safety switch confirms that the induced-draft blower is establishing proper negative pressure before the control board allows ignition. When the switch fails or drifts out of calibration, the furnace locks out and refuses to fire — a very common no-heat complaint.
Pressure switches are calibration-critical. This OEM Goodman switch is factory-set to the exact -1.10 in. WC setpoint the furnace expects. A generic switch with even a slightly different trip point can cause false lockouts or, worse, allow ignition under improper draft. The color-coded Sun Gold housing guarantees you install the correctly rated switch.
Easy to Moderate (2 of 5). Usually 15–20 minutes. Cut power, photograph and disconnect the two spade terminals and the rubber sensing hose, remove the mounting screws, and install the new switch. Reconnect the hose and terminals exactly as before, then test for a clean ignition sequence.
