What Lo (Low Ambient Temperature Warning) Means
Lo is a warning, not a failure code, per LG's digital-and-analog error-code reference: it means the ambient (room) temperature around the refrigerator has dropped below -10 degrees Celsius, and the unit won't perform optimally in that environment.
Common Causes of Lo (Low Ambient Temperature Warning)
- Refrigerator installed in an unheated garage, porch, or outbuilding
- Extreme cold snap affecting an otherwise normal installation location
🔧 One Safe Check You Can Try
Move the refrigerator, if possible, to a location that stays above that threshold - an unheated garage or porch in deep winter is the most common cause - since this is an environment warning rather than an internal fault to repair.
⚠ Why You Shouldn't Go Further Than That
- There's no repair for Lo - it's telling you about the room, not the appliance, so a service call wouldn't find anything to fix inside the unit itself.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
