Kenmore Refrigerator: compressor failure
What is this symptom?
Experiencing Kenmore refrigerator compressor failure can be frustrating. Symptoms include the compressor not running, a lack of cooling, intermittent clicking, or a constant humming sound. These issues may indicate problems with the start relay, compressor motor, or electronic control board, leading to inefficient cooling or complete breakdown.
Important Tips for Kenmore Models
- Kenmore troubleshooting documentation lists a locked compressor, defective electronic control board, or damaged evaporator as causes for compressor not running, with start device issues being common. (Sears Home Services
Possible Causes
Failed start relay / overload / start capacitor
How to Identify: No compressor hum, clicking noises, or compressor fails to start while control board energizes the compressor circuit. Multimeter testing can show open or short circuits in these components.
Part: Start relay, overload protector, start capacitor
Compressor motor internal failure
How to Identify: Compressor makes abnormal noises (loud humming without running, high-pitched or different tone and may overheat, then shut off repeatedly. (iFixit
Part: Compressor assembly
Electronic control board fault
How to Identify: No attempts to start compressor despite correct thermostat settings; other functions may also misbehave.
Part: Main control board
Thermal or PTC protection triggers
How to Identify: Compressor attempts to start then immediately shuts off with clicking; compressor may not run long enough to cool. (–
Part: PTC thermistor / thermal overload protector
DIY Solutions
Test and Replace Start Relay / Overload
- Unplug the refrigerator and locate the compressor start relay and overload protector on the side of the compressor.
- Remove the existing start device and test for continuity with a multimeter following component-specific procedures.
- Replace the start relay/overload with an OEM Kenmore part if tests show failure.
- Reconnect and power on the refrigerator to see if the compressor starts correctly.

Where can I find the model number?
Check the rating label around the door, lid, frame, rear panel, or inside the appliance cabinet. Use the complete model number, including suffixes.
Verify the complete model and part number on the retailer's compatibility page before ordering.
Other parts options
Check related components first; use model search as a fallback.
Compressor
Compresses refrigerant within the sealed cooling system and requires specialized service equipment.
Main Control Board
The central brain of the appliance that controls all components, cycles, and timings.
Thermistor
Measures precise temperature changes and sends resistance feedback to the control board.
