Kenmore Refrigerator Error Codes: Full Diagnosis Guide
Kenmore refrigerators display error codes to flag failed components before the fridge warms up and ruins your food. The catch: Kenmore is not a manufacturer — it's a brand sold under Sears and now Transformco, and different Kenmore refrigerator models are built by three different companies depending on the model-number prefix. Understanding which platform you have is step one, because the error codes are entirely different between platforms. **How to identify your Kenmore refrigerator's manufacturer:** - **Model prefix 106.xxx** — Built by Whirlpool. Uses Whirlpool-style error codes: E0, E1, E2 (thermistor faults), SY EF (evaporator fan fault). Examples: 106.73025601. - **Model prefix 795.xxx** — Built by LG. Uses LG-style Er codes: Er FF (freezer fan), Er rF (refrigerator fan), Er dH (defrost heater), Er IF (ice maker fan). Examples: 795.51833.410. - **Model prefix 253.xxx** — Built by Frigidaire/Electrolux. Uses Frigidaire-style codes: SY CE (communications error), H1 (high temperature). Examples: 253.44323400. The model number label is located inside the fresh-food compartment on the left wall near the top, or on the frame behind the lower crisper drawer.

- SY EF, Er FF, or H1 blinking on the display
Most Likely Causes
- 1
E0 / E1 / E2 — Thermistor Faults (Whirlpool-based 106.xxx)
On Kenmore models built by Whirlpool (106.xxx prefix, e.g. 106.73025601), E0 indicates a fresh-food thermistor fault, E1 indicates a freezer thermistor fault, and E2 indicates an ambient (outside-air) thermistor fault. Thermistors are NTC resistors whose resistance falls as temperature rises — a healthy fresh-food thermistor reads approximately 16.6kΩ at 32°F and 10kΩ at 50°F. Disconnect the thermistor connector and test resistance with a multimeter. An open circuit (OL), shorted circuit (0Ω), or grossly out-of-spec reading confirms failure. Thermistors are inexpensive ($15–$30) and straightforward to replace — the main challenge is accessing the sensor behind the liner.
- 2
SY EF — Evaporator Fan Fault (Whirlpool-based 106.xxx)
SY EF on Whirlpool-platform Kenmore refrigerators means the control board has detected the evaporator fan is not running or not running at the correct speed. The evaporator fan circulates cold air from the freezer evaporator coils into both compartments — when it stops, the fresh-food section warms while the freezer may remain cold initially. Common causes: fan motor failure, ice buildup locking the fan blade (defrost system has failed), or a wiring harness issue between the fan and the control board. First check if the freezer is frost-packed (blocked fan due to defrost failure), then test the fan motor's winding resistance (~100–300Ω on most models) if the blade spins freely.
- 3
Er FF — Freezer Fan Fault (LG-based 795.xxx)
Er FF on LG-built Kenmore refrigerators (795.xxx prefix, e.g. 795.51833.410) means the freezer evaporator fan motor is not operating. This is one of the most common faults on LG-platform Kenmore French door refrigerators. The fan is located behind the rear panel in the freezer compartment. Ice accumulation around the fan shaft or a failed fan motor are the two primary causes. If the freezer is heavily frosted, run a manual defrost first (unplug for 24–48 hours with towels down) before replacing the fan. If the fan blade spins freely by hand but the motor won't run when powered, the motor has failed. Part: EAU61524007 or equivalent.
- 4
Er rF — Refrigerator Fan Fault (LG-based 795.xxx)
Er rF means the fresh-food compartment fan is not operating on LG-platform Kenmore models. This fan draws air from the evaporator into the fresh-food section. Failure causes the refrigerator to warm while the freezer stays cold — a classic symptom pattern. Test the fan motor by removing the rear interior panel in the fresh-food section and verifying the fan blade spins freely and the motor receives power. Fan motor resistance spec: approximately 50–200Ω depending on model.
- 5
Er dH — Defrost Heater Fault (LG-based 795.xxx)
Er dH on LG-platform Kenmore refrigerators indicates the defrost heater is not operating or the defrost cycle is not completing within the expected time window. The defrost heater melts frost from the evaporator coils on a timed schedule (usually every 8–12 hours of compressor run time). Failure causes progressive frost accumulation until the evaporator is fully blocked. Check the defrost heater resistance (typically 20–80Ω when cold), the defrost thermostat (should show continuity when cold, open when hot), and the defrost sensor. Part numbers vary by model — search your full model number.
- 6
Er IF — Ice Maker Fan Fault (LG-based 795.xxx)
Er IF means the ice maker compartment fan is not running on applicable LG-platform Kenmore models. Some LG-based Kenmore French door models have a dedicated fan for the ice maker in the upper fresh-food section. When this fan fails, the ice maker may still produce ice but at reduced capacity, or the ice maker section may warm and cause soft or partially formed cubes. Check the fan for ice blockage and verify motor operation.
- 7
SY CE — Communications Error (Frigidaire-based 253.xxx)
SY CE on Kenmore models built by Frigidaire (253.xxx prefix, e.g. 253.44323400) indicates a serial communication failure between the main control board and a secondary board (dispenser board, temperature control board, or user interface). Causes include a failed control board, a failed secondary board, or a damaged wiring harness between the two. Begin with a power reset (unplug 5 minutes). If SY CE persists, inspect the wiring harness connectors — the most common physical cause is a loose or corroded connector at one of the board plugs.
- 8
H1 — High Temperature Alarm (Frigidaire-based 253.xxx)
H1 on Frigidaire-based Kenmore refrigerators means the compartment temperature has risen above the safe threshold. This is a consequence code — the root cause is usually a failed fan, condenser coil blockage, refrigerant leak, or compressor failure. The H1 alarm should trigger you to check food safety first (discard anything that has been above 40°F for more than 2 hours), then diagnose the root cause. Start by checking condenser coil cleanliness (rear or bottom), condenser fan operation, and evaporator fan operation before suspecting the sealed system.

Quick DIY Checks
Unplug the refrigerator before removing any internal panels, accessing the evaporator fan, or testing any wiring. Refrigerator defrost heaters operate at 120V and can deliver a lethal shock if contacted while energized.
Do not use a heat gun or open flame to defrost an iced-over evaporator — this can damage plastic liners and wiring insulation. Let the ice melt naturally with the refrigerator unplugged, or use a fan to circulate warm room air.
If you suspect a refrigerant leak (oily residue near the compressor, hissing sound, or confirmed no cooling with all fans and heaters working), do not attempt sealed-system repair yourself. Refrigerant handling requires EPA 608 certification.
- 1Identify your Kenmore refrigerator manufacturer by the model number prefix. Pull the model number label from inside the fresh-food compartment (left wall, near the top) or behind the lower crisper drawer. Model 106.xxxxx = Whirlpool-built (E0/E1/E2/SY EF codes). Model 795.xxxxx = LG-built (Er FF/Er rF/Er dH/Er IF codes). Model 253.xxxxx = Frigidaire-built (SY CE/H1 codes). This determines which diagnostic path applies.
- 2Do a power reset before any further diagnosis: unplug the refrigerator for 5 full minutes, then restore power. Many transient communication errors (SY CE, Er codes from power surges) clear with a full power cycle. If the same code returns within a few hours of normal operation, proceed with targeted diagnosis.
- 3For E0/E1/E2 (Whirlpool 106.xxx): set your multimeter to resistance (Ω). Disconnect the thermistor connector (the suspect sensor — fresh-food for E0, freezer for E1) and measure resistance across the two terminals. At room temperature (~70°F), a healthy thermistor reads approximately 7–11kΩ. An open circuit (OL) or a reading near 0Ω confirms a failed thermistor. Part cost: $15–$30.

Repair vs Replace
Most Kenmore refrigerator error codes point to a single inexpensive component — a thermistor, fan motor, or defrost heater. These repairs cost $15–$80 in parts and 1–3 hours of labor. Even a control board replacement at $80–$180 is far cheaper than a new refrigerator. Repair makes sense for units under 15 years old unless the sealed system (compressor or refrigerant) has failed — sealed-system repairs on older units often cost more than replacement.
Est. Repair Cost
$15–$200 depending on failed component (thermistor $15–$30, fan motor $25–$60, defrost heater $20–$50, control board $80–$180)
Est. Replacement Cost
$800–$2,200 for a new comparable refrigerator

Frequently Asked Questions
- How do I know if my Kenmore refrigerator is made by Whirlpool, LG, or Frigidaire?
- Check the model number label inside the fresh-food compartment (left wall near the top) or on the frame behind the crisper drawer. The first three digits of the model number identify the manufacturer: 106 = Whirlpool, 795 = LG, 253 = Frigidaire. For example, model 106.73025601 is a Whirlpool-built Kenmore and uses Whirlpool error codes (E0, E1, SY EF). Model 795.51833.410 is an LG-built Kenmore using LG error codes (Er FF, Er rF, Er dH). Model 253.44323400 is a Frigidaire-built Kenmore using Frigidaire codes (SY CE, H1).
- How do I enter diagnostic mode on a Kenmore refrigerator?
- The diagnostic procedure varies by platform. On LG-based Kenmore models (795.xxx): press and hold the Refrigerator and Ice Plus buttons simultaneously for 3 seconds to enter forced defrost mode ('FF' on display). To enter the full service/diagnostic mode, press both freezer and refrigerator temperature buttons simultaneously and hold for 3 seconds — the display will cycle through sensor readings. On Whirlpool-based Kenmore models (106.xxx), service mode varies by control board generation — consult the tech sheet inside the machine (typically taped to the inside of the fresh-food section). On Frigidaire-based models (253.xxx), press and hold the Freezer Temp UP and DOWN buttons simultaneously for 3 seconds.
- Will my Kenmore refrigerator error code clear on its own?
- Some Kenmore error codes are latching (persistent until the fault is repaired and the code is manually cleared or the unit is power-cycled). Communication errors like SY CE often clear with a power reset. Temperature alarms like H1 will clear once the compartment returns to a safe temperature. Fan fault codes (Er FF, SY EF) will reappear every time the control detects the fault — they won't self-clear until the failed component is replaced. Always perform a power reset first, but if the same code returns, proceed with diagnosis.
