What Does Error Code ER RS Mean on a Kenmore Refrigerator?

Refrigerator temperature sensor fault.

ER RS fires when the control board reads the fresh-food (refrigerator) compartment thermistor as electrically open or shorted, losing valid temperature feedback. It is the fridge-side counterpart to ER FS, which covers the freezer sensor. Without a usable resistance reading, the board can no longer regulate the compartment, so the fridge may run too warm or too cold as cooling free-runs. A failed thermistor, a loose sensor connector, or harness damage behind the interior panels are the usual triggers.

Models affected: LG-built Kenmore refrigerators on the 795 Series platform, plus similar LG-sourced Kenmore models using digital fresh-food thermistors
What owners report: Owners commonly report this code appearing alongside fridge temperatures drifting warm or unusually cold, sometimes after cleaning or moving interior shelves that disturb the sensor plug. A quick reseat of the connector often clears a false trigger, but a genuinely failed thermistor is an inexpensive, clip-in swap that many owners handle themselves.

What Causes Error Code ER RS?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

  1. 1
    Failed refrigerator thermistor 55% of cases
  2. 2
    Loose sensor connector 30% of cases
  3. 3
    Harness damage behind interior panels 15% of cases

How to Fix Kenmore Refrigerator Error Code ER RS

🔧 Easy DIY Est. time: 10–20 min
⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.
  1. 1

    Reseat the connector

    Unplug the unit and reseat the sensor plug behind the fridge interior panel.

    ⚠️ Unplug first.
  2. 2

    Test the thermistor

    Verify resistance changes with temperature; open or shorted readings mean replacement.

  3. 3

    Replace the sensor

    Cheap part, simple clip-in replacement.

Frequently Asked Questions

Can I keep using my Kenmore Refrigerator when error ER RS appears? +
You often can for a cycle or two, but the temperature-sensor issue behind ER RS will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.
What most commonly causes ER RS on a Kenmore Refrigerator? +
Across reported Kenmore refrigerator repairs, the most frequent is failed refrigerator thermistor (55% of cases), loose sensor connector (30%), then harness damage behind interior panels (15%). Check them in that order before replacing any parts.
ER RS keeps coming back after a reset — what should I check next? +
A reset only clears the stored ER RS fault; if it returns, the temperature-sensor problem is still present. Move on to the physical checks — reseat the connector, then test the thermistor — since the code will reappear until the root cause is resolved. This is a beginner-friendly job needing only basic hand tools.
How much does it cost to fix Kenmore Refrigerator error ER RS? +
A DIY repair typically runs $0–$30 in parts, versus $140–$260 for a professional service call, so handling it yourself saves around $140. Expect the work to take about 10–20 minutes.
Which Kenmore Refrigerator models show error ER RS? +
ER RS is documented on LG-built Kenmore refrigerators on the 795 Series platform, plus similar LG-sourced Kenmore models using digital fresh-food thermistors. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
