Kenmore Refrigerator Error Codes by Model Series and System

Kenmore refrigerator codes vary across 106, 253, 795, and 111-series models. Identify sensor, defrost, fan, airflow, communication, Wi-Fi, and door-switch faults, understand control-board LED patterns, and learn which warning signs require prompt refrigerator diagnosis in San Diego.

Kenmore Refrigerator Error Codes for San Diego Homes

Kenmore refrigerators can use very different error-code systems because the brand includes models built on several appliance platforms. A side-by-side unit beginning with 106 may show a single letter in the temperature display, a 795-series bottom-freezer model may use Er-style messages, and a 111-series refrigerator may report sensor faults through Lo/Hi codes or flashes from the main control-board LED. The full model number must therefore be checked before any part is ordered.

Airflow, Temperature, and Communication Display Codes

On compatible Kenmore 106 refrigerators, d in the refrigerator display means the air damper that moves cold air from the freezer into the fresh-food section is stuck. C in the refrigerator display identifies a refrigerator-compartment thermistor failure, while C in the freezer display identifies a freezer thermistor failure.

CF in the freezer display means the main control board and user-interface control are not communicating correctly. The problem may involve loose connections, a damaged wiring harness, the interface control, or the main electronic board.

OP in the freezer temperature display is used on certain Kenmore 253-series French-door models and means the freezer temperature-sensor circuit is open. The sensor, its wiring, and the control-board connection should be checked with the refrigerator disconnected from power.

Sensor and Defrost Codes on 795-Series Models

Er FS points to a freezer temperature-sensor problem, while Er rS identifies the refrigerator temperature sensor. F dS means the freezer defrost sensor has failed or its circuit is shorted.

The similar r dH code means the refrigerator defrost sensor did not rise above the expected temperature during defrost. The cause may involve the defrost fuse, heater, sensor assembly, wiring, or control-board relay.

These codes may appear with weak cooling, frost buildup, uneven temperatures, or a compartment that becomes too warm. A sensor code does not automatically prove that the thermistor alone is defective because damaged wiring or the main control board can create the same result.

Fan, Network, and Wi-Fi Errors

Er IF means the ice-compartment fan is not operating correctly. Ice buildup can block the fan, but the fan motor, wiring harness, or power control board may also be responsible.

Er FF indicates an evaporator-fan failure, while Er CF points to the condenser-fan circuit. These fans support airflow and heat removal, so a failure may lead to poor cooling, unusual operating sounds, or rising compartment temperatures.

Er CO means the main control board and display board have lost communication. E Od identifies a Wi-Fi modem failure on compatible connected refrigerators. The modem wiring and display-board connection should be inspected before either electronic component is replaced.

Lo and Hi Sensor Codes

On compatible Kenmore 111 bottom-freezer models, F1 Lo or F1 Hi identifies the freezer-compartment temperature sensor. r1 Lo or r1 Hi refers to the refrigerator temperature sensor, while i5 Lo or i5 Hi points to the ice-maker temperature sensor.

FD Lo or FD Hi identifies the freezer defrost sensor, and rD Lo or rD Hi identifies the refrigerator defrost sensor. “Lo” and “Hi” describe an electrical reading outside the expected sensor range, not simply a compartment that is too cold or too warm.

Wiring and sensor resistance should be tested using specifications for the exact model. The ice-maker sensor may be built into the complete ice-maker assembly rather than supplied as a separate replacement part.

dr Door-Switch Code

The dr message appears when the control detects the refrigerator door open for more than one hour. Close the door and check that shelves, bins, or food packages are not preventing a complete seal.

If the door is fully closed but dr remains, the door switch, its wiring, or the control-board input may be defective. A failed switch can make the refrigerator behave as though the door is still open even when it is physically closed.

Main Control-Board LED Flicker Codes

Some Kenmore 111 top-freezer refrigerators do not show these faults on the front display. The LED on the main control board flickers, pauses, and repeats a pattern.

One Flicker

One flicker means refrigerator temperature-sensor failure.

Two Flickers

Two flickers mean ambient temperature-sensor failure.

Three Flickers

Three flickers identify the defrost temperature sensor.

Four Flickers

Four flickers mean the control has detected the refrigerator door open for more than one hour.

The control-board area remains electrically live while the refrigerator is plugged in. Homeowners should not touch the board or nearby components. Power must be disconnected before the cover is reinstalled or any wiring is inspected.

Kenmore Refrigerator Error Code Service in San Diego

Record the exact code, the model-number prefix, and whether the refrigerator is cooling, making ice, or developing frost. Move temperature-sensitive food if either compartment is warming. A recurring code usually requires model-specific testing of sensors, fans, wiring, defrost components, electronic controls, or door switches.

Reset Appliance Repair provides Kenmore refrigerator diagnostics in San Diego for airflow faults, temperature-sensor errors, fan failures, defrost problems, communication codes, door-switch alerts, and control-board LED patterns.
