The Goodman B1756020L is a genuine OEM vertical condensate drain pan engineered as a direct-fit replacement for the WAHMS4961P4ACA air handler. Mounted beneath the evaporator coil, it captures condensate as warm return air passes across the cold coil and channels it safely to the drain line — preventing overflow, water damage, and biological buildup inside the cabinet.

Specifications

Part Number: B1756020L
Type: Vertical (upflow/downflow) condensate drain pan
Dimensions: 23 in. x 20 in. (OD)
Brand: Goodman OEM
Equipment: Air Handler
Fits Model: WAHMS4961P4ACA

OEM vs. Generic

This is the genuine Goodman OEM pan, molded to the exact cabinet footprint and drain-port location of your unit. Universal/generic pans often require trimming, re-drilling, or adapters and can leave gaps where condensate escapes. The OEM part drops in with the original mounting points and slope, ensuring proper drainage the first time.

Install Difficulty

Moderate — requires removing the coil access panel and sliding out the existing pan. Allow 30–60 minutes. Power off the unit at the disconnect, clear the drain line, and verify the float switch reseats correctly before restoring power.
