What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model MBE1200AA-1AA — B1376853 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 MBE1200AA-1AA — B1376853.

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 motor mount 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 B1376853 Motor Mount Arm

The B1376853 is a genuine Goodman blower motor mount arm (mounting leg/band) for the MBE1200AA-1AA air handler. The mount arm holds the blower motor in the housing belly band and keeps it concentric with the blower wheel. A bent, broken, or corroded mount arm lets the motor sag or vibrate, which causes wheel rub and noise — this direct-fit arm restores correct motor alignment.

Specifications

Type: Blower motor mount arm / support leg
Fits Model: Goodman MBE1200AA-1AA air handler
Function: Secures and aligns the blower motor in the belly band
Material: Plated steel
Brand: Goodman OEM
Part Number: B1376853

OEM vs. Generic

The genuine Goodman OEM mount arm matches the original bolt pattern and bend geometry, so the motor sits at the correct height and angle with no shimming. Generic substitutes often differ in length or hole spacing, throwing off motor-to-wheel alignment. For a small bracket that controls alignment, OEM is well worth it.

Installation

Difficulty: Easy. A typical job is loosening the belly-band clamp or mount bolts, swapping the arm, and re-torquing. Basic hand tools only; plan 15–20 minutes. Shut off power to the air handler before working near the blower motor.
