LG Refrigerator: not powering on
What is this symptom?
Is your LG refrigerator not powering on? If your appliance shows no lights, sounds, or signs of life when plugged in, it may indicate a power supply issue, a faulty power cord, or a failed control board. This guide will help you troubleshoot and resolve the problem effectively.
Important Tips for LG Models
- LG official support specifically recommends checking outlet and circuit breaker first, and if still no power, service is required
Possible Causes
Power supply issue (outlet/circuit)
How to Identify: No lights or sounds, other appliances on the same outlet also not working; tripped circuit breaker
Part: Outlet/circuit breaker/power supply
Faulty power cord or plug
How to Identify: Visible damage to cord/plug; replacing with known good cord restores power; no signs of power with same outlet on other devices
Part: Power cord/plug
Control board failure
How to Identify: No response when power is applied even after outlet and cord verified; known LG models with control board issues documented by community sources
Part: Main control board
Start relay/thermostat or internal electrical component failure
How to Identify: No compressor start or lights although power supply is good; requires component testing
Part: Start relay/thermostat or internal controls
DIY Solutions
Verify and reset power supply
- Check circuit breaker for trip and reset if needed
- Test outlet with another appliance to confirm power
- Unplug refrigerator, wait 30 seconds, and plug back in

Where can I find the model number?
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.
Other parts options
Check related components first; use model search as a fallback.
Main Control Board
The central brain of the appliance that controls all components, cycles, and timings.
Thermostat
Regulates temperature by turning the heating or cooling system on or off.
Model-compatible Refrigerator parts
Enter the complete model number to browse compatible replacement parts. This is a model-based parts search, not a diagnosis that a specific component failed.
