The Goodman B1756028L Horizontal Drain Pan is a genuine OEM condensate pan engineered as a direct-fit replacement for the Goodman ARPF374316CA air handler. When a cracked, corroded, or warped drain pan starts dripping onto the coil or into the cabinet, replacing it with the factory part is the fastest way to stop water damage and restore proper condensate drainage.
This genuine Goodman OEM pan is molded to exact factory dimensions, so the drain port, mounting tabs, and coil clearances line up the first time. Generic universal pans often require trimming or shimming and can leave gaps that allow water to bypass the pan — a common cause of repeat callbacks. For a sealed, drip-free fit, the OEM part is the right choice.
Moderate — Requires pulling the coil and access panel. Plan 45–60 minutes. Always disconnect power before service and confirm the condensate line and trap are clear after installation. Professional installation recommended for warranty coverage.
