How to fix no power on my LG GR-A207CTBA Refrigerator?
If your LG Refrigerator has no power, it might be due to a cut power cord or a faulty connector insertion, or a faulty connection between the plug and adapter. To address this, replace the components if the power cord is cut, or reconnect the connecting parts if there's a faulty connector insertion or connection between the plug and adapter.
Why is the compressor not operating in my LG GR-A207CTBA Refrigerator?
If the compressor in your LG Refrigerator isn't working, it could be due to a faulty PTC or a frozen compressor. If the PTC resistance is infinite, replace it with a new one. If the compressor is frozen, replace it with a new one, weld, evacuate, and recharge refrigerant.
