The Goodman B1756028L Horizontal Drain Pan is a genuine OEM condensate pan engineered for the AEPF303616BB air handler installed in horizontal (attic or crawlspace) orientation. It collects evaporator coil condensate and directs it to the drain, safeguarding the equipment and the structure below from water intrusion. Because horizontal installs are especially prone to overflow damage, a sound, correctly fitted pan is critical — a cracked or corroded pan should be replaced promptly.
The genuine Goodman OEM pan matches the coil and drain-fitting layout precisely for the horizontal cabinet. Generic pans often misalign with factory drain ports — a serious risk in attic installs where overflow can damage ceilings below. OEM delivers a guaranteed, leak-tight fit.
Moderate to Difficult — Typically 60-90 minutes, often in a tight attic space. Requires disconnecting power, pulling the coil, swapping the pan, and re-sealing drain connections. A licensed HVAC technician is recommended for horizontal applications.
