LG Refrigerator: not starting
What is this symptom?
Is your LG refrigerator not starting? When plugged in, it may show no signs of life—no lights, sounds, or fan activity. This issue can stem from several causes, including power supply problems or internal failures. Knowing how to troubleshoot can save you time and money.
Important Tips for LG Models
- LG support advises checking power cord, outlet, and dedicated circuit as first steps before internal repairs.
Possible Causes
No electrical power at outlet or incorrect dedicated circuit
How to Identify: The outlet has no power, the breaker is tripped, or the circuit is not dedicated; test the outlet with another device.
Part: Power outlet / circuit
Faulty or damaged power cord
How to Identify: Visible damage to the cord or fridge still won’t power on after verifying outlet power.
Part: Power cord
Main control board or internal power supply failure
How to Identify: No lights or activity even after correct power at outlet and functional power cord.
Part: Control board / internal PSU
Internal protective device triggered (e.g., during power surge)
How to Identify: Fridge won’t restart immediately after power outage; may reset after time.
Part: Internal protection/thermal fuse
DIY Solutions
Verify and Restore Power at Outlet
- Unplug refrigerator and check that outlet has power by testing with another device or outlet tester.
- Check house circuit breaker and reset if tripped.
- Ensure the refrigerator is on a dedicated 15 A circuit as specified by LG support.
Inspect and Replace Power Cord
- Unplug refrigerator.
- Visually inspect power cord for cuts, frays, or damage.
- Remove cord if possible and replace with OEM or rated equivalent.
- Reconnect and test.

Check the rating label around the door, lid, frame, rear panel, or inside the appliance cabinet. Use the complete model number, including suffixes.
Verify the complete model and part number on the retailer's compatibility page before ordering.
