The heat exchanger is the heart of your furnace — it transfers combustion heat to the air stream while keeping flue gases sealed away from your home's air. A cracked or corroded exchanger is a safety concern and a common failure on aging furnaces; replacing it with the correct factory part restores safe, efficient heating.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCell count: 6-cell clamshell design\u003c\/li\u003e\n\u003cli\u003eMaterial: aluminized steel for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eFits Goodman GDT070-3 (70K BTU) furnaces\u003c\/li\u003e\n\u003cli\u003eDirect OEM replacement — no modification required\u003c\/li\u003e\n\u003cli\u003ePart number: 2921308S\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a \u003cstrong\u003egenuine Goodman OEM\u003c\/strong\u003e exchanger. Because the heat exchanger is a combustion-critical, safety-rated component, we strongly recommend OEM only. Generic exchangers are rarely offered for this application, and dimensional or metallurgical differences can compromise the seal, cause premature cracking, or void your furnace warranty.
