What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WFM18090S4BXCB — 2539306S is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty. You can verify this by checking the data plate on your Goodman equipment which lists the model number WFM18090S4BXCB — 2539306S.

My AC fan is not spinning. What part do I need?

A fan that does not spin, spins slowly, or makes grinding or squealing noises needs a new motor. Grinding means the bearings have failed. Squealing means the bearings are dry. No spin with a humming sound means the capacitor may be the issue. Check the motor capacitor before replacing the entire motor.

Is this blower housing compatible with Bryant or Payne systems too?

Many Goodman parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across multiple brand labels with different model numbers. To verify cross-compatibility, check your Bryant or Payne equipment service manual for cross-compatible part numbers, or contact info@nationalhvacparts.com with your model number for confirmation.

The Goodman 2539306S Blower Housing is a genuine OEM 10 x 8 inch scroll assembly for the Goodman/Amana WFM18090S4BXCB furnace and compatible units. The housing channels air from the blower wheel into the heat exchanger and supply plenum — a cracked, corroded, or damaged scroll causes rattling, air-flow loss, and poor heating performance.

This factory part is stamped and formed to Goodman's original dimensions so the blower wheel and motor mount align perfectly, preserving the correct blade-to-cutoff clearance that quiet, efficient operation depends on.

Specifications

OEM Part Number: 2539306S
Size: 10 x 8 inch blower housing / scroll
Fits: Goodman/Amana WFM18090S4BXCB and compatible furnaces
Material: Galvanized steel scroll assembly
Accepts OEM blower wheel B1368016S and matching motor mount

OEM vs. Generic

Aftermarket housings frequently vary in cutoff-plate position and mounting-flange spacing, which throws off wheel clearance and forces field modification. This genuine OEM 2539306S matches the original geometry exactly, so the wheel, cutoff, and motor mount line up on the first try with no cutting or shimming.

Install Difficulty

Moderate (3 of 5). Requires pulling the blower assembly, transferring the motor and wheel, and confirming wheel-to-cutoff clearance. Plan 45–90 minutes and have a nut driver, wheel puller, and setscrew wrench on hand. Mark wiring before disassembly.

My AC fan isn’t spinning. What part do I need?

Is this blower housing compatible with Bryant or Payne too?

Many Goodman parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers.

Should I use OEM or aftermarket for my Goodman blower housing?

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
