The Goodman 0221F00031PBB 14-inch Blower Door Panel is a genuine OEM access cover for GMPN040-3 equipment. The blower door seals the blower compartment and, on most furnaces, holds in the door interlock (safety) switch — meaning a warped, rusted, or missing panel can actually prevent the unit from firing. This factory panel restores a proper seal, correct airflow, and safe operation.
This is the OEM Goodman panel (0221F00031PBB), formed to the exact cabinet dimensions so the door-interlock switch seats correctly and the compartment seals tight. Generic or fabricated panels frequently miss the switch flange and leak air. For safe, code-correct operation, use the OEM door.
Easy (1 of 5). Lift the new panel into the door track or fasten the retaining screws — a 5-minute, tool-light swap. Confirm the door seats fully so the interlock switch closes.
Turn off power before opening the blower compartment.
