OEM vs. Generic

This is the authentic Goodman OEM pan, molded to the exact dimensions and drain-port placement of your unit — guaranteeing a leak-free, drop-in fit. Universal generic pans are often close but require trimming or shimming and can misalign the drain outlet, leading to standing water and float-switch nuisance trips. For drain pans, OEM fitment is strongly recommended.

Installation Difficulty

Moderate. Requires removing the coil to access and reseat the pan; budget 45–60 minutes. Confirm the drain line is clear and pitched correctly before reassembly.
