LG Refrigerator Not Cooling? Compressor Control Board EBR65640204 – Fix No-Cool Fast

If your LG or Kenmore Elite refrigerator is not cooling, running warm, or the compressor won't start, the compressor control board is the most common cause. In most LG French door and bottom-freezer refrigerators, the compressor control board (PCB assembly) manages inverter compressor operation, fan sequencing, and defrost timing. When it fails, the compressor stops running, temperatures rise in both compartments, and the unit may display error codes. ⚡ Common failure point in LG linear compressor refrigerators. Part EBR65640204 is the genuine OEM replacement PCB assembly that restores full compressor control — no modifications required.

❓ Is This the Right Part?

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

• ✔ Refrigerator has power — interior lights and display are on
• ✔ Evaporator and condenser fans run (or run intermittently)
• ✔ Compressor is confirmed not starting or clicking off immediately
• ✔ Start relay has been tested and is not the cause
• ✔ ONLY problem is no cooling or compressor not running despite power being present

⚙️ Installation

Skill Level: Moderate — 30–45 minutes. Unplug the refrigerator and allow capacitors to discharge for 5 minutes before handling the board. The compressor control board is located at the rear bottom of the unit behind the access panel — remove the panel screws, photograph all harness connections, disconnect and swap the board, then reconnect all harnesses in the same positions. Handle the board by its edges only to avoid static damage, and ensure all connectors are fully seated before restoring power.
