The Goodman B1756021L Horizontal Drain Pan is a genuine OEM condensate pan built for ATUF182416AA air handlers mounted in the horizontal (attic or crawlspace) orientation. It captures condensate runoff from the evaporator coil and routes it to the drain connection. Because horizontal installs sit above living space, a failed pan can cause serious water damage — an OEM replacement restores safe, leak-free drainage.

OEM vs. Generic

This genuine OEM pan is shaped for horizontal mounting with the correct pitch toward the drain outlet so water cannot pool. Generic pans frequently lack the proper slope and lip height for side-mount use, risking overflow into the attic. OEM ensures correct fit and dependable drainage.

Installation Difficulty: Moderate

Rated Moderate. Shut off power, open the coil compartment, remove the old pan, transfer drain fittings, and install the new pan with proper slope toward the outlet. Confirm the secondary/drain line is clear and test drainage. Allow 30–45 minutes.
