The Goodman 0154A00000BL Drain Pan Gasket is a genuine OEM sealing gasket engineered for the WAHMS3743P4ABA air handler. It forms the watertight seal between the drain pan and the cabinet, preventing condensate from wicking past the pan and causing water damage, rust, or microbial growth inside the unit. A cracked, flattened, or missing gasket is one of the most common causes of nuisance water leaks at the air handler, and replacing it restores the factory seal.

Specifications

Part Number: 0154A00000BL
Type: Drain pan / condensate seal gasket
Brand: Goodman (also fits select Amana air handlers)
Fits Model: WAHMS3743P4ABA
Equipment: Air Handler
Material: Closed-cell foam sealing gasket

OEM vs. Generic

This is the genuine Goodman OEM gasket, cut to the exact die profile of the original so it seats flush against the pan flange with no field trimming. Generic foam strip is cheaper but rarely matches the OEM thickness and compression, which can leave gaps and lead to repeat leaks. For a one-time, leak-free repair, the OEM part is the reliable choice.

Installation Difficulty

Easy — peel, position, and seat the gasket on a clean, dry pan flange. No tools or refrigerant work required. Most homeowners and techs complete the swap in under 15 minutes.
