Refrigerator Not Cooling? Inverter Board 011666-000 – Fix Compressor Failure Fast

If your refrigerator compressor won't run or the unit can't hold temperature, a failed inverter board is the most common cause. In most refrigerators, the inverter board controls compressor speed and power delivery using variable-frequency drive technology. When it fails, the compressor stops running entirely or runs erratically, causing the fridge to warm up and food to spoil. ⚡ Common failure point in modern inverter-driven refrigerators. Part 011666-000 is the genuine OEM replacement that restores proper compressor control and stable temperature regulation.

❓ Is This the Right Part?

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

• ✔ Refrigerator powers on and interior light works
• ✔ Fans run but compressor does not start or cycles off immediately
• ✔ Power supply and outlet confirmed OK
• ✔ ONLY problem is compressor not running / refrigerator not cooling

Not sure? Send us your model number — we'll confirm before you order.

🔧 Common Symptoms

• Refrigerator runs but does not cool — compressor never starts
• Compressor hums briefly then shuts off (thermal overload tripping)
• Fridge temperature drifts above set point over several hours
• Error codes related to compressor or inverter on display panel

✔ If these symptoms match, this is the most likely failed component in the system.

✔ In most cases, replacing this inverter board restores normal compressor operation immediately.
