Goodman 0221F00008PDG 14" Access Door Panel

The Goodman 0221F00008PDG is a genuine OEM 14-inch access door panel for Goodman GMTH045-3 furnaces. This panel covers the blower or burner compartment and is a functional safety component — it seats against the door interlock switch that cuts power when the panel is removed, and it maintains the sealed airflow path the furnace needs for correct combustion and blower operation. A warped, rusted, or missing panel can cause the furnace to short-cycle or refuse to run.

Specifications

Part Number: 0221F00008PDG
Type: Access / blower compartment door panel
Size: 14 inches
Material: Painted galvanized steel
Fits: Goodman GMTH045-3 furnaces
Function: Seals compartment, engages door safety switch

OEM vs. Generic

The genuine Goodman panel is stamped to the exact cabinet dimensions and insulation pattern, so it presses the door interlock switch reliably and preserves the sealed air path. Universal or aftermarket panels rarely match the flange bends and switch alignment, which can defeat the safety interlock. For proper fit and safe operation, OEM is strongly recommended.

Installation Difficulty

Easy (1/5) — No tools beyond aligning the panel into its lower tabs and latching the top. Under 5 minutes. Confirm the door safety switch engages fully when the panel is seated.

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