The Goodman 2528007S flue collector plate is a genuine OEM combustion component for the GMNT100-4 gas furnace. The collector plate caps the heat-exchanger outlets and channels spent combustion gases into the flue or induced-draft assembly, forming a critical gas-tight seal between the burner section and the venting system. A corroded, cracked, or warped collector plate can leak flue products, hurt efficiency, and pose a carbon-monoxide risk, so a compromised plate should be replaced promptly.
The OEM collector plate matches the exact heat-exchanger port pattern, gasket seat, and induced-draft flange of the GMNT100-4. Because this part seals combustion gases, an imprecise generic fit can leak. OEM ensures a proper, safe seal and correct draft performance.
Moderate (3/5). Requires removing the inducer/vent connection and existing gasket, transferring or replacing seals, and torquing fasteners evenly to seat the plate. Because it affects combustion venting, a combustion/CO check after install is recommended. Best performed by an experienced DIYer or HVAC technician; budget 45–60 minutes.
