Dacor Refrigerator Error Code Er rS — Refrigerator Compartment Sensor Fault
What this means
Error code Er rS on Dacor refrigerators indicates the fresh food compartment temperature sensor (thermistor) has returned a reading outside the acceptable range. This sensor monitors the main refrigerator section temperature and helps the control board regulate the compressor and damper system. A failed sensor can cause the compartment to overcool (freezing food) or undercool (food spoiling). Dacor refrigerators, built on Samsung's platform, use the same Samsung-style error code format.
Alternate codes: Er-rS, Error rS, rS error
Step-by-step fix
4 stepsReset the refrigerator
Unplug the refrigerator for 5 minutes or use the button reset (hold Power Freeze + Fridge for 8 seconds). Allow 10 minutes after restoring power for the control board to take a fresh sensor reading.
If Er rS appeared after a temporary power outage, a reset often clears it permanently.
Locate the refrigerator sensor
Open the refrigerator door. The temperature sensor is typically located behind the air duct cover at the top or rear of the compartment. Remove the cover (usually clips or 2 screws) to access the sensor.
On Dacor column refrigerators, the sensor may be inside the evaporator housing. Check your model's tech sheet for the exact location.
Test the sensor
Disconnect the sensor and test resistance with a multimeter. At refrigerator temperature (37°F / 3°C), the sensor should read approximately 7,000–8,000 ohms. At room temperature (77°F / 25°C), it should read about 5,000 ohms. Significantly different readings indicate a failed sensor.
Place the disconnected sensor in a glass of ice water to simulate a known temperature and verify the reading is in the expected range.
Replace the sensor
If the sensor is out of specification, replace it. The sensor clips or screws into its mounting position. Route the wire along the original path and reconnect. Reassemble the cover and restore power.
Allow 24 hours after sensor replacement for the refrigerator temperature to fully stabilize.
When to call a professional
If the sensor tests fine but Er rS persists, the control board's sensor input may be faulty. A Dacor technician should verify before replacing the expensive control board.
