Quick answer
SS is a sensor code: the manual calls it a water tank temperature detection issue, while another list says pantry sensor shorted or open.
Model compatibility: LG reuses codes across series and model years, so SS may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
SS is a water tank temperature sensor fault, described elsewhere as a shorted or open pantry sensor.
The SS code on an LG refrigerator is a sensor warning, and LG’s two help pages word it a little differently. One says SS indicates an issue in the detection of the water tank temperature and that it reduces the appliance’s performance. The other says an SS error code indicates a shortened or open pantry sensor.
What to do
Neither entry gives owner troubleshooting steps. The manual’s action is to request service, and the unit will require a repair service.

Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
