LG Refrigerator Door Sagging or Won’t Close? 4984JJ3003A Hinge Bushing – Fix It Fast

If your LG refrigerator door sags, doesn’t seal properly, or swings open on its own, the door hinge bushing is the most common cause. In LG French door and bottom-freezer refrigerators, the plastic hinge bushing supports the door pivot pin — when it wears or cracks, the door drops out of alignment, the gasket loses contact, and the refrigerator works harder to maintain temperature. ⚡ Common wear item in LG LFX, LMX, and LFXS series refrigerators. Part 4984JJ3003A is the genuine OEM replacement bushing that restores proper door alignment and a tight seal immediately.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Refrigerator is cooling normally — compressor and fans work
• ✔ Door gasket is intact — no tears or missing sections
• ✔ Door hinge pin is not bent or broken
• ✔ Door visibly sags, sits lower than the opposite door, or swings open
• ✔ ONLY problem is door alignment, seal, or self-closing behaviour

🔧 Common Symptoms

• Refrigerator door sags or sits lower than the other door — most common complaint
• Door swings open on its own instead of staying closed
• Door gasket not sealing — condensation or frost around the door frame
• Refrigerator runs constantly or struggles to hold temperature
• Visible gap between door and cabinet on one side
• Cracked, worn, or missing plastic bushing visible at the hinge point

✔ If these symptoms match, the hinge bushing is the most likely failed component.

✔ In most cases, replacing this bushing restores proper door alignment and seal immediately.
