The Goodman B1376857 Motor Mount Arm is a genuine OEM support leg that anchors the blower motor band to the blower housing on Goodman GDI125-5 gas furnaces. These arms bolt to the blower scroll and hold the motor mount band (typically three legs per motor), suspending the motor centered in the blower wheel. Bent or fatigued arms let the motor drift off-center, producing wheel rub, rattle, and accelerated bearing failure.

Specifications

  • Type: Blower motor mount arm / support leg
  • Fits: Goodman GDI125-5 furnace
  • OEM Part Number: B1376857
  • Material: Zinc-plated steel
  • Pairs with: B1376851 motor mount band

OEM vs. Generic

This OEM Goodman arm matches the factory bolt pattern and length of the GDI125-5 blower housing. Generic universal legs frequently need bending or elongated slots to line up and can leave the motor misaligned. The OEM arm restores the original geometry exactly.

Install Difficulty: Easy

Straightforward for a DIYer or tech. Disconnect furnace power, remove the blower assembly, unbolt the old arm, and fasten the replacement in the same holes. Replace all worn arms together for even support. Typical time: 20–30 minutes. Verify power is off before you begin.

Frequently Asked Questions

Does this Motor Mount fit my Goodman GDI125-5 Furnace — B1376857?
Yes. This is the factory-specified OEM motor mount for the Goodman GDI125-5 Furnace — B1376857. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the motor mount on my Goodman GDI125-5 Furnace — B1376857?
Difficulty: Medium-Hard (1–2 hrs)
Step 1: Turn off breaker. Step 2: Note motor specs: HP, RPM, voltage, rotation direction. Step 3: Remove old motor from mounting. Step 4: Transfer fan blade to new motor. Step 5: Mount new motor, reconnect wiring. Step 6: Restore power, verify rotation direction.
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 motor mount 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 motor mount?
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.
