How do I fix a fridge that suddenly lost all power?
Answer
If the fridge is completely dead while the outlet works, check the dedicated breaker or GFCI first, then try a longer unplug reset and listen for a click or hum when power returns. No lights, beeps, or display after those checks usually means a failed control board, main board fuse, or power supply that needs service.
Before you start: stop right away if…
- Do not open sealed electrical compartments or bypass fuses on the main board yourself.
- If the outlet itself is dead, stop fridge troubleshooting and fix the circuit or outlet first.
Follow these steps
Confirm the outlet and circuit
Plug a lamp or phone charger into the same outlet the fridge uses. If that works, check the breaker panel for a tripped fridge or kitchen breaker and reset it fully off, then on. Also reset any GFCI outlet in the kitchen or garage that shares the circuit.
You should see: The outlet stays live and any tripped breaker or GFCI is reset.
Do a short power reset
Unplug the fridge for about 5 minutes, then push the plug firmly all the way into the outlet. Watch the control panel for any light, beep, or error code as power returns.
You should see: The panel shows some sign of life, or it stays fully dark so you know the short reset did not help.
Try a longer reset and listen
Unplug again for about 10 minutes. Plug it back in and listen closely for a relay click, compressor hum, or a brief display flash. If nothing happens, leave the unit unplugged and arrange service rather than repeatedly cycling power.
You should see: You either hear or see a startup response, or confirm the fridge remains completely dead.
Protect food and get model details ready
Move perishable food to a cooler if the fridge stays off. Note the model and serial from the sticker (often inside the fresh-food section) before contacting LG support or a refrigerator technician.
You should see: Food is safeguarded and you have the model info needed for service.

Extra tips
What to look for: Completely dead panel with no lights or display, outlet that tests good, other kitchen outlets still working, and any click, hum, or brief light after plugging back in.
Before you change anything: Confirm the wall outlet actually powers another appliance. Do not force open sealed electrical covers on the fridge. Keep food safety in mind if the unit stays off for hours. Unplug before inspecting the cord or rear power plug.
