Amana-Goodman 2821302S Primary Heat Exchanger 5-Cell OEM Furnace Replacement

The Amana-Goodman 2821302S is a genuine OEM primary heat exchanger designed as a direct replacement for Goodman and Amana gas furnaces. This 5-cell heat exchanger packaging assembly is engineered to restore safe, reliable heating performance in compatible furnace units.

The heat exchanger serves a critical function inside the furnace: it transfers thermal energy from the combustion gases to the circulating air, allowing the blower to distribute warm air throughout the space while keeping combustion byproducts safely separated from the breathable air supply. A failed or cracked heat exchanger is a serious safety concern, making prompt replacement with a genuine OEM part essential.

Key Features:

• Genuine OEM Part — manufactured by Goodman Mfg. to original factory specifications for Amana and Goodman HVAC equipment
• 5-Cell Design — multi-cell construction maximizes surface area for efficient heat transfer
• Durable Construction — built to withstand high combustion temperatures and demanding operating cycles
• Direct Replacement — replaces worn, cracked, or failed primary heat exchangers in compatible furnace models
• OEM Part Number: 2821302S (also referenced as 28213-02S)

Compatible furnace models include GMPN040-3, GMPN060-3, GMPN080-4, GMPN100-4, GMPN120-5, GMN100-1, GMPE125-5, GMPE125-5A, GSM100-4, and GSMS100-4. Always confirm your furnace model number before ordering, as heat exchanger sizing and configuration can vary between models. Shut off electrical power and gas supply to the furnace before beginning any replacement work.
