Refrigerator Not Cooling Evenly? Evaporator Fan Motor 4681JB1027C – Fix Airflow Fast
When a refrigerator develops warm spots, stops cooling evenly, or loses cooling entirely despite the compressor running, a failed evaporator fan motor is one of the most common causes. In most LG and Kenmore French door and bottom-freezer refrigerators, the evaporator fan motor circulates cold air from the evaporator coil throughout the fresh food and freezer compartments. When it fails, airflow stops, temperatures rise unevenly, and the compressor runs continuously trying to compensate. ⚡ Common failure point in LG-built French door and bottom-freezer refrigerators. Part 4681JB1027C is the genuine OEM replacement fan motor that restores full airflow and even cooling immediately upon installation.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Your refrigerator powers on and the compressor is running
- ✔ The evaporator coil is not frost-blocked (or has been manually defrosted and the problem returned)
- ✔ You can hear the compressor running but feel little or no airflow from the vents inside the fridge
- ✔ ONLY problem is uneven cooling, warm spots, or no airflow despite the compressor running

🔧 Common Symptoms
- Refrigerator section warm or developing warm spots despite compressor running
- No airflow or very weak airflow from interior vents
- Freezer cooling but fresh food section not cooling
- Loud humming, grinding, or no sound at all from the evaporator fan area
✔ If these symptoms match, this is the most likely failed component in the system.
✔ In most cases, replacing this evaporator fan motor restores full airflow and even cooling immediately.

While the evaporator compartment is open, inspect the evaporator fan blade and wire harness connector for cracks or corrosion. A damaged blade or corroded connector can cause the new motor to fail prematurely. Replacing the blade and cleaning the connector takes 5 minutes and ensures the repair lasts.
⚙️ Installation
Skill Level: Moderate — 30 to 45 minutes. Disconnect power before servicing. Remove the freezer contents and rear interior panel to access the evaporator fan assembly. Disconnect the wiring harness, remove the mounting screws, and swap in the new 4681JB1027C motor. Reconnect the harness, reassemble the panel, restore power, and confirm airflow from the interior vents before reloading the freezer.

💡 Pro Tip
With the fridge unplugged, manually spin the evaporator fan blade — it should spin freely with no resistance. If it's seized or grinds, the motor bearings have failed and 4681JB1027C is your fix. Also check for 13.5V DC at the motor connector with the fridge running; no voltage means the control board or wiring harness is the issue, not the motor itself.
