What dS
actually means.
The sensor the defrost cycle depends on has shorted or come disconnected. On models with two such sensors the letter in front tells you which: F dS is the freezer one and r dS the refrigerator one. LG lists nothing an owner can do about it.

Before you book,
in this order.
Each step comes from LG's own guidance for dS on its refrigerators. Follow it to the end: the last card says whether this is a visit.
Write down the full code, including any F or r before it, since it tells the technician which sensor to test.
Look for frost building on the back panel inside the freezer and mention it if you see it.
Book a repair visit.
What not to do
It is not dH. dH means a defrost cycle ran too long; dS means the control cannot read the defrost sensor at all.

In LG's own words
A dS error code indicates a short or disconnection of the defrosting sensor.
Every code on this site is taken from the manufacturer's documentation, never from a forum or a parts listing. Shown as dS, F dS or r dS depending on the model; the S may look like a 5.
