What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WFD18045S3AXCB — 2539305S 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 WFD18045S3AXCB — 2539305S.

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 2539305S is the OEM 10 x 6-inch blower housing (scroll) for the WFD18045S3AXCB furnace and compatible Goodman/Amana models. This housing encloses the blower wheel and motor, directing conditioned air through the heat exchanger and into the duct system with the correct velocity and static pressure.

A cracked, corroded, or damaged housing causes airflow loss, excessive noise, wheel rubbing, and can throw off temperature rise across the heat exchanger. Replacing the full housing restores the furnace's engineered airflow path and quiets blower operation.

Specifications

Type: Blower housing / scroll assembly
Dimensions: 10 x 6 inch blower opening
Function: Encloses blower wheel; channels supply airflow
Fits: Goodman WFD18045S3AXCB and compatible furnace models
Part number: 2539305S

OEM vs. Generic

The OEM 2539305S matches the factory cutoff plate, motor mount, and wheel clearance exactly, so the blower wheel spins true and airflow specs are preserved. Aftermarket housings often force re-drilling and can create wheel rub or airflow imbalance. For a structural airflow component, OEM is the safe choice.

Installation Difficulty

Hard (4/5). Requires pulling the blower assembly, transferring the motor and wheel, setting wheel-to-cutoff clearance, and re-balancing. Best handled by an experienced tech; budget 60–90 minutes and disconnect power first.

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

Fan not spinning, spinning slowly, or making grinding/squealing noises = motor failure. Grinding = bearings failed. Squealing = bearings dry. No spin + hum = check the motor capacitor first before replacing the entire motor.

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. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

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.
