Error codeEr rt
ApplianceRefrigerator
Er rt: the refrigerator is complaining about its room temperature sensor. Expect to see Er rt on 795-series bottom-freezer units sold as Kenmore or Kenmore Elite.
What the manual pins it on
Condition: shorted sensor or faulty wiring.
Part: room temperature sensor.
Owner reset: not offered.
So the sensor plus the wires connected to it need a technician’s inspection. The manual offers no reset to try at home.
Letters differ by one character, so double-check which one your display shows.
