The Goodman B1756013L Vertical Drain Pan is a genuine OEM condensate pan designed for ATUF182416AA air handlers installed in the vertical (upflow/downflow) orientation. The pan collects condensate from the evaporator coil and channels it to the drain line. A cracked or rusted pan leads to water leaks, ceiling damage, and mold — replacing it with the correct OEM pan protects your home and equipment.
This genuine OEM pan is molded to the exact coil footprint with correctly located drain ports and slope for full drainage. Generic pans often pool water due to wrong pitch or misaligned outlets, causing overflow. OEM guarantees proper fit, correct drain location, and reliable condensate flow.
Rated Moderate. Power down, remove the coil access panel, slide out the old pan, transfer drain fittings, and seat the new pan beneath the coil. Verify the drain line is clear and test for level drainage. Budget 30–45 minutes.
