Amana-Goodman 20170903AS Cover/Gasket

The Amana-Goodman 20170903AS Heat Exchanger Cover/Gasket is an essential OEM kit designed to restore the seal of the combustion chamber in high-efficiency gas furnaces. This assembly includes both the furnace heat exchanger cover and the corresponding high-temperature gasket, engineered to maintain precise static pressure and prevent combustion gas bypass. Constructed from heavy-duty sheet metal and resilient sealing materials, this Goodman furnace replacement part ensures the integrity of the secondary heat exchanger assembly, which is critical for preventing furnace pressure switch trips and ensuring safe flue gas venting. As a factory OEM part, it offers exact dimensional compatibility for Amana heat exchanger sealing, allowing technicians to resolve air leakage issues that compromise thermal efficiency. Utilizing this HVAC collector box kit during preventative maintenance or corrective service helps protect the system from moisture-induced corrosion and optimizes the combustion process for long-term reliability in Janitrol and Goodman-Amana systems.

• Engineered Precision: Matches 20170903AS specifications for a seamless fit on compatible AMVC and GMVC furnace models.
• Complete Sealing Solution: Includes both the heat exchanger cover and sealing gasket to eliminate the need for separate sourcing.
• Pressure Stability: Restores proper airflow dynamics to prevent nuisance pressure switch lockout codes.
• Industrial Durability: Heat-resistant materials withstand the aggressive environment of condensing furnace heat exchangers.

Is the gasket included with the 20170903AS cover?
Yes, this is a kit that includes both the metal collector cover and the necessary high-temperature gasket for a complete furnace heat exchanger repair.

Why is my furnace pressure switch failing with this part?
If the heat exchanger gasket is not seated correctly or if the cover is warped, it can cause vacuum leaks. Ensure all mounting fasteners are torqued to spec to maintain a gastight seal.

Can I use RTV silicone instead of the provided 20170903AS gasket?
It is highly recommended to use the OEM Gasket provided in this kit to ensure chemical compatibility and proper thickness for pressure switch calibration.
