Error code rD Lo/Hi
Appliance Refrigerator
Quick answer

rD Lo and rD Hi flag a failed refrigerator defrost sensor on Kenmore bottom-freezer Trio refrigerators with numbers starting 111.

Model compatibility

Kenmore reuses codes across series and model years, so rD Lo/Hi may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

The refrigerator-side defrost sensor reports a failure.

Overview

Kenmore bottom-freezer Trio refrigerators (numbers starting 111) can show rD Lo or rD Hi. Either way the refrigerator defrost sensor is reported as failing, and the code resets once it is repaired.

Owner steps in the manual

  • Switch the refrigerator off at the plug.
  • Inspect the sensor wiring that leads to the control board.
  • Fix damaged wires.

Meter work

After that the manual measures resistance across the sensor circuit. Replacement of the defrost sensor follows when the number is outside 8,000 to 40,000 ohms. A technician carries this out.
