The Goodman B1756020L Vertical Drain Pan is a genuine OEM condensate pan sized 23 x 20 inches OD for Goodman AEPF30361AA air handlers in vertical (upflow/downflow) configurations. It captures coil condensate and channels it to the drain line, preventing water damage, overflow, and microbial buildup from a cracked or corroded original pan.
This OEM pan matches the original mounting points, drain port location, and coil footprint exactly. Universal or generic pans frequently misalign with factory drain fittings and coil rails, risking leaks. OEM ensures a leak-free, drop-in fit.
Moderate (3/5) — Requires removing the coil/blower section to access and swap the pan, then re-sealing the drain connection. Plan 45–90 minutes and verify proper drainage slope before restoring service.
