Quick answer
Determine whether the refrigerator has no power at all or has power but the compressor has not started. Check the plug, outlet, and breaker once using dry hands. If the outlet works but the refrigerator remains dead, or the breaker will not reset, stop troubleshooting and use LG or qualified electrical service.
Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
Look at the interior light or display without opening panels and confirm whether any control responds when a door opens or a button is pressed.
Expected result: Everything is dark, or the display and lights work while the compressor is quiet.
Next step: Use the matching power path below and do not remove electrical covers.
Why this matters
Why: A completely dark unit suggests incoming power or control supply; live controls shift attention to operating state or compressor start.
-
Check 2
With dry hands, inspect the plug for looseness or visible damage and test the same outlet with a small known-working device only if safe.
Expected result: The plug is loose/damaged, the outlet is dead, or the outlet works for another device.
Next step: Seat an undamaged plug fully; leave damaged wiring or a dead outlet to an electrician.
Why this matters
Why: LG identifies a loose plug or defective outlet as a reason the refrigerator cannot start.
-
Check 3
Check the refrigerator's circuit breaker and reset it once only after the appliance is safely disconnected or the model instructions permit it.
Expected result: The breaker resets and the refrigerator returns, or it trips again or will not reset.
Next step: Do not repeatedly reset a tripping breaker. Disconnect safely and arrange service.
Why this matters
Why: A one-time interruption may be external; a repeat trip or failed reset can indicate an appliance fault or building electrical issue.
-
Check 4
If controls have power but the compressor does not start, note whether the refrigerator was recently moved, serviced, or left without power.
Expected result: The appliance is recovering from a move or outage, or it remains silent with rising temperatures.
Next step: Keep doors closed during a short recovery check; request service if cooling does not resume.
Why this matters
Why: A restart delay can be temporary, but persistent silence with warming food requires diagnosis.

Helpful context
Understand the symptom
Start with the symptom
A refrigerator that is silent after a power interruption is a power-path question first. A silent compressor with a live display is different from a completely dark appliance and should not be treated as the same fault.
When checks do not resolve it
Need a professional?
Stop and request LG or qualified electrical service if the breaker repeatedly trips, the outlet or cord is damaged, the outlet is live but the refrigerator stays dead, or food temperatures rise.
Common questions
FAQ
Should I keep resetting the breaker if the LG refrigerator will not start?
No. LG links repeated or non-resetting trips with possible product, wiring, outlet, or breaker faults. Stop after a safe check and obtain qualified help.
What if the display works but I cannot hear the compressor?
First allow for a normal cycle or recent recovery only if the refrigerator is still maintaining temperature. If food warms or the compressor stays silent, request service.
