The back wall inside the fresh food compartment of a refrigerator, a small temperature sensor clipped beside the air vents, shelves soft in front of it.

showing ER rS

The temperature sensor in the fresh-food compartment is shorted or disconnected, so the board no longer knows how cold that side is.

Three short steps, about a minute.

Before you book,
in this order.

Each step comes from LG's own guidance for ER rS on its refrigerators. Follow it to the end: the last card says whether this is a visit.

01

Check whether the fresh-food side is too warm or too cold, and keep an eye on the food.

02

Have the full model number ready when you book.

03

Book a visit — this one is a sensor or its wiring.

Still there?

It usually turns into controls and sensors. Book with the code and the model number.

What not to do

Do not keep adjusting the temperature setting. The board cannot act on a setting while it cannot read the compartment.

In LG's own words

A rS error code indicates a short or disconnection of the refrigerator sensor.
LG US support: refrigerator error code list (archived January 2025)

Every code on this site is taken from the manufacturer's documentation, never from a forum or a parts listing. LG uses FS for the freezer sensor and F dS or r dS for the defrost sensors; the prefix varies by model.

Questions
about ER rS.

Can I clear ER rS myself?
Check whether the fresh-food side is too warm or too cold, and keep an eye on the food. If it comes back, it needs a visit.
Is there anything I can do at home about ER rS on my LG?
LG offers no owner fix, because the sensor or its wiring is shorted or disconnected. Keep an eye on the food and book a visit with the model number handy.
Why does changing the temperature not help with LG ER rS?
The board can no longer read the fresh-food compartment, so it has nothing to compare a new setting against. Adjusting the dial just adds guesswork until the sensor circuit is repaired.

Back to your everyday

Still showing ER rS?

Book with the exact characters, the full model number, and whether it is still cooling — on a code, that is the whole starting point.
