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.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 2820005S\u003c\/li\u003e\n\u003cli\u003eFunction: Flue gas collection \/ draft transition\u003c\/li\u003e\n\u003cli\u003eCompatible Model: Goodman GSM080-4\u003c\/li\u003e\n\u003cli\u003eEquipment Type: Gas Furnace\u003c\/li\u003e\n\u003cli\u003eMaterial: Aluminized \/ stainless steel\u003c\/li\u003e\n\u003cli\u003eIncludes: Collector box with gasket surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003egenuine OEM Goodman\u003c\/strong\u003e collector box matches the original heat-exchanger flange pattern and gasket seat exactly.
