Odd. The freezer temperature lights only show from -16 to -22 and the fridge section +8 to +2
Freezer section should be minus 18 or thereabouts and the fridge +4.
Whatever, the red light says its too warm.
Check the manual here:

See the minor problems entry on page 15 and the one on page 16 - you may just need to defrost - yes even a frost free freezer can need that sometimes.
The pther thing to watch is the drain hole at the back of the fridge and the tube below it, should be kept clear ("A" in picture 8 on page 21) - a bit of old fashioned plastic covered net curtain wire is usually a great tool for that
