LG Refrigerator: not functioning

Professional Repair Guide

What is this symptom?

If your LG refrigerator is not functioning, you may notice that there are no lights on the display, no sounds from the compressor, or any cooling activity. This issue can stem from a lack of electrical power, a failure in the internal control board, or a damaged power cord. Addressing these problems promptly is essential to prevent food spoilage.

Urgency: High

Important Tips for LG Models

  • LG official troubleshooting prioritizes checking power supply, cord, and breaker before deeper diagnostics.

Possible Causes

No electrical power supply to the refrigerator

How to Identify: No display lights, no sounds when plugged in; other appliances on the same circuit may work or not

Part: Power cord / circuit breaker / outlet

Internal electronic control board failure

How to Identify: Refrigerator has no signs of life even after confirming power supply, or intermittent behaviour after resets

Part: Main control board

Faulty power cord

How to Identify: Visible damage or test with a known good cord/outlet; fridge gets no power while outlet is known good

Part: Power cord

Blown internal fuse/thermistor or safety cut-off

How to Identify: No power but external supply and cord are confirmed good — requires disassembly to check internal safety components

Part: Internal fuse/thermal cutoff
