Kenmore Freezer NO-COOLING Error: Freezer Not Cooling (No Electronic Code)
The kenmore freezer no-cooling error is a fault signal from the control board — this guide walks through what it means, common causes, and safe diagnostic steps. Kenmore Chest Freezer Not Cooling — What It Means Kenmore chest freezers in the 253.1xxxx series — as well as older basic upright models — use a mechanical […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. A Kenmore freezer that is not cooling at all cannot maintain safe frozen food temperatures. Move all frozen food to an alternate freezer or cooler with dry ice immediately. Do not rely on the unit for food storage until the cause is diagnosed and repaired.
Can I reset the code?
No. A mechanical no-cooling failure on a Kenmore chest or basic upright freezer cannot be cleared by unplugging and replugging. The start relay, thermostat, or compressor has physically failed and requires inspection and part replacement.
When to stop immediately?
Stop if you notice: Compressor start relay shake test is silent but compressor still does not start after relay replacement — indicating compressor winding failure, Thermostat bypass confirms compressor is functional but clicking or humming recurs after thermostat replacement.
Symptoms You May Notice
Freezer interior is at room temperature despite the unit being plugged in
The most unmistakable symptom — food that should be solidly frozen is soft, thawed, or beginning to spoil, and the interior cabinet feels no colder than room temperature even after the unit has been running for several hours.
Compressor is silent when the room is quiet and no vibration is felt
On Kenmore chest and basic upright freezers, the compressor produces a steady low-frequency hum and vibration when running. If the unit is completely silent and no vibration is felt with a hand on the side of the cabinet, the compressor is not running — likely due to a failed start relay or overload protector.
Compressor hums briefly then clicks off repeatedly without cooling
A humming sound followed by a click after 2–5 seconds, repeated every few minutes, is the classic sign of a failed start relay on Kenmore chest and upright freezers. The compressor motor tries to start, cannot because the relay does not provide the starting current boost, and the overload protector trips to protect the motor windings.
Warm air felt blowing from the rear condenser area
On Kenmore chest and basic upright freezers where the thermostat is stuck closed but cooling has failed, the condenser fan and compressor may continue drawing current, producing noticeably warm exhaust air at the rear grille while the interior stays warm.
Possible Causes
Failed compressor start relay
The start relay plugs into the compressor body and provides the current pulse needed to start the motor winding on each cooling cycle. When the relay fails, the compressor cannot start. Shaking the relay near your ear: a rattle confirms the relay's internal element has broken and it must be replaced.
DIY PossibleFailed mechanical thermostat (stuck open)
The mechanical thermostat on Kenmore chest freezers and basic uprights is a sealed capillary tube sensor that controls when the compressor runs. If the thermostat fails in the open position, it never signals the compressor to start, leaving the cabinet warm even though all other components are functional.
DIY PossibleFailed compressor (seized motor or winding failure)
After years of service, the compressor motor windings fail or the compression mechanism seizes. This is the most expensive repair and is often not economically viable on older Kenmore chest freezers — replacement of the unit may be more cost-effective than compressor replacement.
Requires ProfessionalSafe Checks You Can Do

1
Test the compressor start relay with the shake test
Unplug the Kenmore chest or upright freezer. Pull the unit away from the wall. Locate the compressor — a large, domed black component at the rear bottom. The start relay is a small rectangular or cylindrical component plugged into the side of the compressor body (usually with a push-on connector). Pull it free from the compressor terminals. Shake it near your ear — if you hear any rattling inside, the relay has failed internally and must be replaced. A good relay is silent when shaken.
The start relay for most Kenmore chest freezers costs from $8 and is one of the most cost-effective first parts to replace when diagnosing a no-cooling complaint. Order by the Kenmore model number (253.1xxxxx) from SearsPartsDirect or RepairClinic to get the correct relay for your compressor.

Test the mechanical thermostat by bypassing it temporarily
Unplug the Kenmore freezer. Locate the mechanical thermostat control knob (typically inside the chest or on the exterior of the upright). Follow the capillary tube to the thermostat body and the two wire terminals. Disconnect the two wires from the thermostat terminals and temporarily connect them together (short them) with a small jumper wire or by holding the bare ends together. Plug the unit in briefly and listen — if the compressor starts immediately, the thermostat has failed open and needs replacement. Unplug before releasing the jumper.
This bypass test is safe to perform for 30 seconds to confirm compressor function, but do not leave the thermostat permanently bypassed — the compressor will run continuously without the thermostat to cycle it off, risking overheating.
Tools required
When to Call a Professional
Contact a qualified technician if:
- Compressor hums but does not start even after start relay replacement — suggests motor winding failure requiring compressor replacement
- Compressor runs after start relay replacement but evaporator coil never frosts — indicating refrigerant loss requiring a licensed technician
- Compressor draws high current (above nameplate amperage) on an ammeter — confirming seized compressor requiring replacement
