OEM Goodman Horizontal Drain Pan for ARPF182416BA — B1756021L

The Goodman B1756021L Horizontal Drain Pan is the genuine OEM condensate pan built specifically for Goodman/Amana ARPF182416BA air handlers installed in the horizontal position — common in attic and crawlspace applications. Horizontal pans see constant exposure to standing condensate, so a cracked or rusted pan is one of the most frequent causes of ceiling stains and water damage. This factory replacement restores reliable drainage and protects the home.

OEM vs. Generic

A horizontal pan must match the coil's slope and drain location precisely or condensate pools and overflows. Universal aftermarket pans rarely match these dimensions. The genuine OEM B1756021L seats exactly as the factory intended, aligning with the primary and secondary drain ports for proper flow.

Installation Difficulty

Moderate to advanced. Horizontal pan replacement usually means partially withdrawing the coil and working in a tight attic or crawlspace, so plan 60–90 minutes. Many homeowners prefer to have a licensed HVAC technician perform this swap. Disconnect power and clear both drain lines before reinstalling.
