The condensate pan collects and channels moisture produced during the cooling cycle away from the coil and internal components, protecting your air handler from corrosion, water damage, and microbial growth. A cracked, warped, or clogged drain pan is one of the most common causes of ceiling stains and water leaks — replacing it with the correct OEM part restores proper drainage and protects the equipment around it.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e B1756028L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Horizontal condensate drain pan\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (OEM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e WAHMV3137P4AAA air handler\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrientation:\u003c\/strong\u003e Horizontal installation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Molded corrosion-resistant pan\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine OEM Goodman drain pans are molded to the exact contours of the coil and cabinet, so the drain outlet, slope, and mounting points line up perfectly.
