Kenmore Fridge Freezing Food? Causes & Fix
Most likely the air damper is stuck open, letting too much freezer air into the fresh-food section, or the thermistor is reading warmer than reality so the board overcools — a control-board fault or, on older units, a failing mechanical cold-control can also freeze the fridge, so check the temperature setting and…
How the fresh-food temperature is set#
The freezer is the only source of cold in a frost-free Kenmore; a damper meters that cold air into the fresh-food compartment and a thermistor tells the board when to close it. If the damper hangs open or the thermistor under-reports the temperature, the board keeps sending cold and the fridge over-chills. Kenmore builds these on the 106 and 596 Whirlpool platform and the 795 LG platform, which sense and meter slightly differently.
Causes at a glance#
| Likely cause | What you'll notice | Share of cases | First move |
|---|---|---|---|
| Damper stuck open | Produce freezing near the vent | 35% | Check the damper for free travel |
| Thermistor reads warm | Whole fridge overcools | 25% | Test the fresh-food thermistor |
| Control board fault | Overcools despite good sensor | 15% | Inspect the control board |
| Mechanical cold-control (older) | Dial units freeze on any setting | Occasional | Test the cold-control thermostat |
| Setting too cold | Improves when dialed warmer | Occasional | Adjust the temperature setting |

Working through the causes#
Damper stuck open (35%). The air damper on the Whirlpool-platform 106 and 596 units sits at the top rear of the fresh-food compartment where freezer air enters; the 795 LG platform uses a DC-motor damper behind a top panel. Stuck open, it floods the fridge with cold air and freezes food near the vent. The damper is checked for free travel and its motor tested. Thermistor reads warm (25%). The fresh-food thermistor reports compartment temperature to the board. If it reads warmer than actual, the board keeps cooling past target and the whole fridge over-chills. The thermistor, part family around WPW10384183, is tested and replaced. Control board fault (15%). The board processes the thermistor input and commands the damper. A fault in its temperature-regulation circuit can overcool even with a good sensor, and the board is replaced after the sensor is cleared. Mechanical cold-control — older models (occasional). Some older 106 and 253 series units use a mechanical cold-control thermostat instead of electronics. A failing dial control can leave the compressor running cold on any setting; the cold-control is tested and replaced. Setting too cold (occasional). Kenmore models number their controls differently — 1 to 9 on some, actual degrees on digital — so a high setting can simply overcool. Try a warmer setting and see whether it recovers before opening anything.
Quick checks first#
- Check the temperature setting; Kenmore numbering varies, so a high number may just be too cold.
- Move temperature-sensitive items away from directly in front of the air vent.
- Watch whether the damper cycles or is stuck open at the top rear of the compartment.
- Note which platform you have — 106/596 (Whirlpool) or 795 (LG) — since the damper hardware differs.
- If a warmer setting does not help, the thermistor or damper is the likely cause.
Safety First — Know the Risks
Refrigerant (R-134a/R-600a) requires EPA certification to handle. Improper discharge is a federal violation and health hazard. Our techs are licensed and insured — let them handle the risk.

Preventing a repeat#
- Do not store produce and beverages directly in front of the air inlet vent.
- Keep the fridge about three-quarters full so cold air distributes evenly.
- Verify the setting after anyone adjusts it, since numbering is easy to misread.
- Have the thermistor checked if food keeps freezing despite a moderate setting.
- Keep the air vent at the top rear clear so cold air distributes instead of pooling on one shelf.
