What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model GUI050-2 Furnace — 1439389S 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 GUI050-2 Furnace — 1439389S.

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 1439389S 9 x 6 in. Blower Housing

The 1439389S is a genuine Goodman 9 x 6 inch blower housing (scroll) built for GUI050-2 gas furnaces. The housing encloses the squirrel-cage blower wheel and shapes the airflow the blower produces, directing conditioned air into the supply plenum. A cracked, rusted, or deformed housing causes air leaks, whistling, and reduced CFM that starves the home of heat. This OEM scroll matches the factory 9 x 6 discharge dimensions and mounting points for a direct replacement.

OEM Part Number: 1439389S
Part Type: Blower Housing / Scroll
Discharge Size: 9 x 6 inches

OEM vs. Generic

The genuine Goodman housing is dimensioned to the GUI050-2's exact blower-wheel diameter and cabinet cutout. Aftermarket housings vary in scroll geometry and outlet size, which can reduce airflow efficiency or require cabinet modification. The OEM 1439389S drops in with correct wheel clearance and mounting alignment.

Installation Difficulty

Moderate (3/5) — Requires pulling the blower assembly, transferring the motor and wheel into the new housing, and re-seating it in the cabinet. Cut power first. Plan on 45–60 minutes; a socket set and comfort with sheet-metal assemblies are recommended.

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.

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.
