Kenmore Refrigerator Error Codes: Complete List with Fixes

Kenmore refrigerators are among the most common in American homes, but here is what most owners don't realize: Kenmore doesn't manufacture anything. The Kenmore brand (originally Sears) contracts production to Whirlpool, LG, Electrolux/Frigidaire, and GE — which means your Kenmore fridge's error codes depend entirely on who actually built it. This guide is the only cross-manufacturer Kenmore refrigerator error code reference you need.

Step 1: Identify Your Kenmore Refrigerator's Manufacturer

Before looking up any error code, find your model number on the sticker inside the fridge (usually on the left wall near the top, or behind the crisper drawers). The first three digits tell you who made your refrigerator:

• 106.xxxxx — Built by Whirlpool (most common for side-by-side models)
• 253.xxxxx — Built by Frigidaire/Electrolux (common for top-freezer models)
• 795.xxxxx — Built by LG (Elite French-door and bottom-freezer models)
• 363.xxxxx — Built by GE (select models)
• 596.xxxxx — Built by Whirlpool (newer side-by-side and French-door)
• 970.xxxxx — Built by LG (recent Elite models)

Why this matters: A "Er IF" code on a 795-series (LG-built) means ice fan failure, while the same symptom on a 106-series (Whirlpool-built) displays as "C" or "CF." Using the wrong troubleshooting steps for your manufacturer wastes time and can cause damage.

Whirlpool-Built Kenmore Refrigerators (106.xxxxx, 596.xxxxx)

These are the most widely sold Kenmore refrigerators. They use Whirlpool's control architecture and share parts with Whirlpool and KitchenAid fridges.

CF or C — Condenser Fan Error

The condenser fan (located near the compressor at the bottom-rear) is not running or running below expected RPM.

Common causes:

• Dust and pet hair buildup on condenser coils restricting fan airflow
• Fan motor failure (part W10189703)
• Fan blade hitting debris or ice buildup
• Wiring harness disconnected at fan motor connector

How to fix:

1. Pull the fridge away from the wall and remove the rear lower panel (4 screws).
2. Clean the condenser coils with a coil brush and vacuum the area thoroughly.
3. Check that the fan blade spins freely by hand. Remove any debris wrapped around the shaft.
4. If the fan doesn't spin or hums without turning, replace the condenser fan motor. Part W10189703 costs $25–$50.

Part cost: Condenser fan motor W10189703 runs $25–$50. Professional repair: $150–$250 total.

PO — Power Outage

The control board detected an interruption in power supply and is alerting you that temperatures may have risen during the outage.

How to fix:

1. Press any button to clear the PO display.
2. Check food safety — if the outage lasted more than 4 hours, use a thermometer to verify the freezer is below 0°F and the fridge below 40°F.
3. If PO appears without a known outage, check the power cord connection and the wall outlet. A loose plug or a tripping GFCI can cause intermittent PO codes.

EF or Er FF — Evaporator Fan Error

The evaporator fan in the freezer compartment is not circulating cold air. This fan pushes cold air from the freezer into both the freezer and fresh food sections.

Common causes:

• Ice buildup around the fan from a defrost system failure
• Evaporator fan motor failure (part W10438708)
• Blocked fan blade from ice or packaging material

How to fix:

1. Open the freezer and listen — you should hear the fan running when the door is closed (use the door switch to simulate a closed door). Silence means the fan is not operating.
2. Remove the freezer back panel (evaporator cover) to access the fan. If ice is encasing the fan, manually defrost with a hair dryer on low heat, keeping it 6+ inches from plastic parts.
3. If the fan motor is dead (no ice blockage, motor doesn't spin when powered), replace it. Part W10438708 costs $30–$55.

Part cost: Evaporator fan motor W10438708 is $30–$55. Professional repair: $150–$275.

Er dH or dF — Defrost Heater / Defrost Circuit Failure

The adaptive defrost system detected that the defrost heater did not raise the evaporator temperature as expected. Frost builds up on the evaporator, gradually reducing cooling performance.

Common causes:

• Defrost heater element open (part WPW10278727)
• Defrost bi-metal thermostat failed open
• Defrost timer or adaptive defrost control board fault
• Defrost termination thermostat stuck

How to fix:

1. Remove the freezer back panel and inspect for heavy frost on the evaporator coils. Heavy frost confirms a defrost system failure.
2. Test the defrost heater continuity with a multimeter — it should read 20–40 ohms. Infinite resistance means the heater is open and needs replacement.
3. Check the bi-metal thermostat — it should show continuity when cold (below 50°F).
4. The defrost heater assembly WPW10278727 costs $30–$60 and is a common failure point.

Part cost: Defrost heater WPW10278727 is $30–$60. Professional repair: $175–$300.

LG-Built Kenmore Refrigerators (795.xxxxx, 970.xxxxx)

These are the premium Kenmore Elite models — French-door, bottom-freezer, and counter-depth units. They use LG's linear compressor technology and LG's error code system.

Er IF — Ice Fan Error

The ice compartment fan is not operating correctly, causing ice maker malfunction and potential temperature rise in the freezer.

Common causes:

• Ice buildup around the fan assembly from a drain issue
• Fan motor failure (part ABA72913413)
• Frost clogging the ice duct

How to fix:

1. Remove the ice maker assembly and inspect the fan behind it.
2. If ice is blocking the fan, defrost manually with warm water or a hair dryer.
3. Check the drain at the bottom of the ice compartment — a clogged drain causes water to refreeze around the fan. Clear with hot water and a turkey baster.
4. If the fan motor itself is dead, replacement ABA72913413 costs $40–$65.

Er FF — Freezer Fan Error

The freezer evaporator fan is not running. Cold air cannot circulate to maintain freezer temperature.

Common causes:

• Fan motor failure (part EAU60694510)
• Frost accumulation on fan blades from defrost failure
• Wiring harness issue between fan and main control board

How to fix:

1. Listen at the back of the freezer compartment. With the door closed (press the door switch), you should hear the fan. Silence means it has failed.
2. Remove the freezer rear panel and check for ice around the fan. If ice is present, a defrost issue is causing secondary fan failure.
3. Test motor leads — the fan motor should show 150–300 ohms resistance.
4. Replacement fan motor EAU60694510 costs $35–$60.

Er CO — Communication Error

The main control board and display board cannot communicate — a serious error that disables temperature control.

Common causes:

• Wire harness between door display and main board damaged (often at the door hinge where wires flex)
• Main control board failure
• Display board failure
• Power surge damage

How to fix:

1. Open and close the fridge door slowly while watching the display — if it flickers, the wire harness through the hinge is damaged.
2. Unplug for 5 minutes and replug. If Er CO clears temporarily, the connection is intermittent.
3. Inspect the harness at the top hinge — this is the most common failure point. Replacement harness costs $20–$40.
4. If the harness is intact, the main control board (part EBR73304205, $80–$150) is likely failed.

Er FS — Freezer Sensor Error

The freezer temperature sensor (thermistor) is reading out of range — either shorted or open circuit.

Common causes:

• Failed thermistor (part EBG61106803)
• Disconnected sensor connector
• Wire break in sensor harness

How to fix:

1. Locate the freezer thermistor (clipped to the evaporator or side wall).
2. Measure resistance — should be approximately 5K ohms at 77°F. A reading of 0 ohms (short) or infinite (open) confirms failure.
3. Check the connector at the main board for corrosion or loose pins.
4. Replacement thermistor EBG61106803 costs $10–$25.

Frigidaire/Electrolux-Built Kenmore Refrigerators (253.xxxxx)

These Kenmore models share their platform with Frigidaire refrigerators. Error codes display as two-character alphanumeric combinations.

SY EF — Evaporator Fan Circuit Failure

The control board cannot detect the evaporator fan running — identical to the code on Frigidaire and Electrolux fridges.

Common causes:

• Fan motor failure (part 242077702)
• Ice blockage on the evaporator fan
• Wiring harness fault between fan and control board

How to fix:

1. Listen at the freezer vent — no airflow sound confirms the fan is stopped.
2. Remove the freezer back panel and check for ice encasing the fan blade.
3. Measure fan motor resistance — should read 200–800 ohms.
4. If the motor is dead, replacement 242077702 costs $35–$60.

SY CF — Communication Failure

Board-to-board communication lost between the user interface (display) and the main control board.

Common causes:

• Ribbon cable or wire harness damaged at the door hinge
• Main control board failure (part 5304514710)
• UI display board failure

How to fix:

1. Power-cycle the unit for 5 minutes.
2. Inspect the ribbon cable between the door UI board and the rear main board.
3. Check the door hinge harness for pinched wires — this is the most common failure point on side-by-side Kenmore/Frigidaire models.
4. Main control board replacement 5304514710 costs $100–$200.

DF — Defrost Circuit Error

The defrost system is not raising the evaporator temperature as expected during the defrost cycle.

Common causes:

• Defrost heater failure (part 242044113)
• Defrost thermostat stuck open
• Control board defrost relay failure

How to fix:

1. Remove the freezer back panel and check for thick frost on the evaporator coils.
2. Test defrost heater continuity — should read 20–40 ohms.
3. Check the defrost bi-metal thermostat — should show continuity when cold.
4. Force a defrost cycle via the service mode (hold both temperature buttons for 3 seconds on some models).
5. Defrost heater assembly 242044113 costs $25–$50.

GE-Built Kenmore Refrigerators (363.xxxxx)

Less common but still found in some top-freezer and side-by-side models. These use GE's diagnostic system.

FF — Freezer Fan Fault

The freezer evaporator fan motor is not detected by the control board.

Common causes:

• Fan motor failure (part WR60X10074)
• Ice buildup on fan blades
• Wiring issue at fan connector

How to fix:

1. Remove the freezer back panel and inspect for ice around the fan.
2. Test the fan motor — should read 200–500 ohms.
3. Check the connector at the main board for corrosion.
4. Fan motor WR60X10074 costs $25–$45.

CC — Condenser Coil Issue

The condenser coils are too hot or airflow is restricted, causing the compressor to overheat.

How to fix:

1. Clean the condenser coils at the rear or bottom of the fridge.
2. Ensure 2+ inches of clearance on all sides for ventilation.
3. Check that the condenser fan is running. If the fan is dead, replace it before the compressor overheats.

Kenmore Refrigerator Diagnostic Mode

Most Kenmore refrigerators have a diagnostic/service mode, but the entry method depends on the manufacturer:

• Whirlpool-built (106/596): Press the door switch 3 times within 10 seconds, then press the refrigerator temp button once. The display enters diagnostic mode and cycles through sensor readings and error history.
• LG-built (795/970): Press and hold Freezer Temp + Fridge Temp simultaneously for 5 seconds. The display shows the last 4 error codes stored in memory.
• Frigidaire-built (253): Hold both temperature set buttons for 5 seconds. The display scrolls through stored fault codes.
• GE-built (363): Press and hold the temperature UP and DOWN buttons simultaneously for 3 seconds to enter service mode.

Frequently Asked Questions

Q: How do I find out who manufactured my Kenmore refrigerator? A: Look at the first three digits of your model number (found on a sticker inside the fridge). 106 or 596 = Whirlpool, 795 or 970 = LG, 253 = Frigidaire/Electrolux, 363 = GE. This determines which error codes and parts apply to your unit.

Q: Can I use Whirlpool parts in my Kenmore refrigerator? A: If your Kenmore model starts with 106 or 596, yes — these are Whirlpool-built and use identical parts. A Whirlpool part number will fit directly. However, a Whirlpool part will NOT fit a 795-series (LG-built) Kenmore, even if the appliance looks similar from the outside.

Q: Why does my Kenmore Elite show an error code not in the Kenmore manual? A: Many Kenmore manuals are generic and don't cover every code for every manufacturer platform. Kenmore Elite French-door models (795.xxxxx) are LG-built and use LG error codes — searching "LG refrigerator" plus your error code often yields better results than searching "Kenmore."

Q: My Kenmore refrigerator is beeping but shows no error code. What should I do? A: Continuous beeping without a code usually means the door has been open too long (door ajar alarm) or the temperature has risen above safe levels. Close the door firmly, wait 10 minutes, and listen for the beeping to stop. If it continues, check the door seal for gaps and verify the gasket is making full contact. On LG-built models, pressing the Alarm button silences the alert temporarily.

Q: How long do Kenmore refrigerator parts take to get since Sears closed? A: Kenmore parts remain widely available through third-party suppliers because the actual parts are Whirlpool, LG, Frigidaire, or GE parts with different labeling. Once you identify the manufacturer via the model number prefix, you can order the OEM part directly — often with faster availability and lower cost than ordering the Kenmore-branded equivalent.

When to Call a Professional

Some Kenmore refrigerator issues go beyond DIY repair:

• Sealed system problems (compressor, evaporator, condenser) — These require EPA-certified refrigerant handling and specialized recovery equipment. Never attempt compressor replacement yourself.
• Repeated communication errors (Er CO, SY CF) — Intermittent wiring faults in the hinge harness can be difficult to diagnose without specialized connector testing tools.
• Multiple error codes appearing together — Simultaneous codes often indicate a control board failure sending incorrect signals to multiple components.
• LG linear compressor issues on 795-series — LG's linear compressor has known longevity issues. If your LG-built Kenmore is 5–8 years old and running warm with no error code, the compressor may be weakening.
