The Goodman 0221F00008PDG is a genuine 14-inch access door panel for the GMTH045-3A furnace and compatible Goodman/Amana models. This front cover panel seals the blower/burner compartment, supports proper airflow, and — critically — depresses the door interlock safety switch that allows the furnace to run. A cracked, rusted, or missing panel can trigger nuisance shutdowns, air leaks, and reduced efficiency.

Specifications

Part number: 0221F00008PDG
Type: Access / door cover panel
Nominal width: 14 inches
Fits: Goodman GMTH045-3A furnace
Material: Painted formed steel
Function: Compartment seal + interlock switch actuation

OEM vs. Generic

OEM Goodman panels match the exact dimensions, flange bends, and switch-tab location your furnace expects, ensuring the door safety switch engages reliably. Generic or aftermarket panels often fit loosely, leak air, or fail to trip the interlock — leaving you with a furnace that won't start. Fit and safety make OEM the right call here.

Install Difficulty: Easy

No tools beyond simple hand tools are typically needed. Power down the furnace, remove the old panel, and seat the new panel so it fully engages the door interlock switch. Confirm the switch clicks and the blower compartment is sealed.

Compatible with GMTH045-3A. Verify panel dimensions before ordering.
