Goodman 2820005S Flue Collector Box

The Goodman 2820005S flue collector box is a factory-original combustion venting component for GSM080-4 gas furnaces. It captures flue gases exiting the heat exchanger and channels them into the induced-draft blower and vent, maintaining proper draft and safe combustion. Because it lives in the hottest, most corrosive part of the furnace, the collector box is a common wear item — pinhole rust or cracked seams can leak flue products and trip the pressure switch. Replacing it with the correct OEM part restores safe, code-compliant venting.

Specifications

Compatible Model: Goodman GSM080-4

OEM vs. Generic

This genuine OEM Goodman collector box matches the original heat-exchanger flange pattern and gasket seat exactly. Aftermarket boxes frequently seal poorly, risking flue leakage and nuisance pressure-switch faults. Choosing OEM ensures a gas-tight fit and protects the manufacturer warranty.

Installation Difficulty

Advanced — involves opening the combustion area, replacing gaskets, and verifying draft after reassembly. Plan 60–90 minutes. A combustion-safety check with a manometer is strongly recommended. Professional HVAC installation is advised for any flue-side repair.
