Amana-Goodman 2820006S Collector Box

The Amana-Goodman 2820006S Collector Box is a critical 21-inch OEM recovery component designed for high-efficiency Goodman and Amana gas furnaces. Built to withstand the corrosive environment of condensing heat exchangers, this flue collector box provides an airtight seal to manage post-combustion exhaust gases and condensate. In the field, a cracked or failing collector box often leads to secondary heat exchanger issues or pressure switch trips; replacing it with this genuine Goodman replacement part ensures the venting system maintains its designed static pressure and structural integrity.

This 21-inch collector box is engineered for precision fitment in multi-positional furnace configurations, including 100k BTU models like the GMPN100-4. It replaces legacy part numbers such as B2810006, providing a direct-drop solution for technicians performing furnace repair or seasonal maintenance. By effectively directing flue gases toward the draft inducer, it maintains peak HVAC system efficiency and adheres to critical ventilation safety standards.

• OEM Precision: Guaranteed compatibility with Goodman-Amana 80% and 90%+ AFUE gas furnaces.
• Corrosion Resistance: Fabricated with durable materials designed to handle high-temperature flue gases and acidic condensate.
• Direct Replacement: Replaces B2810006, simplifying 21-inch cabinet system repairs.
• Optimized Ventilation: Ensures consistent draft through the heat exchanger for reliable performance.

What are the signs that a collector box needs replacement?
Technicians should look for visible cracks, water stains from condensate leaks, or recurring pressure switch fault codes that indicate an airflow restriction within the flue collection path.

Is the foam seal included with the 2820006S?
While this is the primary flue collector box assembly, always verify if a separate gasket set or high-temp RTV is required for your specific furnace model to ensure a gas-tight seal during installation.

Which furnace cabinet sizes is this part compatible with?
This part is specifically sized for 21-inch furnace cabinets. Always cross-reference the model and serial number of the unit to confirm the exact fitment before beginning the teardown.
