What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model GMT070-4 Furnace — 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 GMT070-4 Furnace — 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.

Goodman 2539306S Blower Housing (10 x 8 in.)

The Goodman 2539306S is a genuine OEM 10 x 8 inch blower housing (scroll) for the GMT070-4 gas furnace. This housing surrounds the squirrel-cage blower wheel and directs conditioned air into the supply plenum. A cracked, rusted, or distorted housing causes rubbing, excessive noise, air leakage, and reduced CFM, which in turn drives high-limit trips and uneven heating. A correctly dimensioned OEM housing restores rated airflow and quiet operation.

Specifications

Part Number: 2539306S
Type: Blower housing / scroll assembly
Dimensions: 10 in. x 8 in. wheel size
Compatible Model: GMT070-4
Brand: Goodman (OEM)
Equipment: Gas furnace

OEM vs. Generic

Blower performance depends on the housing's exact cutoff geometry and cubic-inch volume. The OEM 2539306S matches the wheel and motor your GMT070-4 was engineered around, preserving CFM and static pressure. Generic housings can throw off airflow balance and create wheel interference. OEM keeps the system in spec.

Installation Difficulty

Moderate to Advanced. Requires pulling the blower assembly, transferring the motor and wheel, and setting the wheel-to-cutoff clearance. Plan 60–90 minutes; less-experienced users should have an HVAC technician perform the swap.

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.
