The Goodman 0130F00041 is a genuine OEM air-proving pressure switch engineered for the AMH81155CXCA 80% AFUE gas furnace and compatible Goodman/Amana models. It monitors negative pressure in the venting system and proves the inducer draft before the control board allows ignition — a critical safety function that prevents the furnace from firing without adequate exhaust flow.
Our OEM 0130F00041 is calibrated to the exact -0.90" WC setpoint specified for your furnace, ensuring correct draft-proving and safe ignition. Generic equivalents often carry looser tolerances that can cause nuisance lockouts or, worse, allow firing under weak draft. For a life-safety component we recommend the genuine OEM switch.
Easy (2/5). Disconnect power, transfer the two wire leads and the rubber tubing to the new switch, and remount with the existing screw. Most homeowners and technicians complete this in under 15 minutes. Always verify the setpoint stamped on the switch matches -.90" WC.
