The Goodman B1756017L Vertical Drain Pan is a genuine OEM condensate pan designed for WAHMS1931P4ACA as well as ARUF036 and ARUF042 air handlers configured for vertical (upflow/downflow) installation. The drain pan captures condensate that forms on the evaporator coil and channels it to the drain line. A cracked, rusted, or clogged pan leads to water leaks, ceiling stains, water damage, and float-switch shutdowns — making this an essential maintenance and repair part.

Specifications

Configuration: Vertical drain pan
OEM Part Number: B1756017L
Brand: Goodman (Amana compatible)
Equipment: Air Handler
Fits Models: WAHMS1931P4ACA, ARUF036, ARUF042
Material: Corrosion-resistant molded composite

OEM vs. Generic

This genuine OEM pan is molded to the exact coil footprint and drain-port locations of the supported cabinets. Generic universal pans rarely seal correctly against the coil slab and can allow secondary overflow. For leak-free drainage and proper float-switch fitment, the OEM B1756017L is the correct choice.

Installation Difficulty

Moderate (3/5). Requires opening the air handler cabinet, sliding out or lifting the evaporator coil, swapping the pan, and reconnecting the condensate drain and any safety float switch. Disconnect power and have a towel ready for residual water. Plan on 45–90 minutes; a technician can complete it during a routine service call.
