The Goodman B1756028L Horizontal Drain Pan is a genuine OEM condensate pan engineered for the ATUF374316AA air handler installed in a horizontal (attic or crawlspace) orientation. In horizontal mounts the pan runs the full length of the coil to catch condensate across its slope and route it to the drain fitting. A failed pan in an attic install is especially damaging — replacing it with the factory part prevents ceiling leaks, mold, and float-switch trips.

Fits Model: ATUF374316AA Air Handler

OEM vs. Generic

Horizontal pans are unforgiving on fit — the slope and outlet position must match the coil exactly or water backs up under the coil. This OEM pan reproduces the factory drainage geometry, while generic substitutes often pool water and leak. For attic and horizontal installs, OEM is strongly recommended.

Install Difficulty

Moderate to Advanced. Requires sliding out the coil, swapping the pan, and re-leveling the unit so condensate drains toward the outlet. Plan 60–90 minutes; tight attic access adds time. Verify the secondary drain and float switch, and disconnect power before servicing.
