The Goodman B1756028L Horizontal Drain Pan is the genuine OEM condensate pan designed for Goodman ARPF48601BA air handlers mounted in the horizontal position (attic and crawlspace installs). It collects condensate from the underside of the evaporator coil and directs it to the primary drain, preventing the water damage that horizontal installations are especially prone to.
This genuine Goodman OEM pan matches the factory length, depth, and drain-port placement required for proper horizontal drainage. Because horizontal pans depend on precise pitch to avoid standing water, generic substitutes frequently allow pooling and microbial growth. OEM guarantees correct drainage geometry.
Difficulty: Moderate to Advanced — Horizontal pan replacement requires accessing the unit in tight attic/crawlspace conditions and removing the coil. Plan 60–90 minutes. Confirm a secondary float switch is installed per code. Professional installation recommended.
