Kenmore Refrigerator: compressor continuously running
What is this symptom?
Is your Kenmore refrigerator compressor running continuously? This issue often results in higher energy usage and heat buildup at the back of the unit, indicating potential problems such as dirty condenser coils, faulty door seals, or an inefficient compressor. Understanding these causes can help you troubleshoot effectively.
Important Tips for Kenmore Models
- Kenmore guides specifically note defrost thermostat and thermistor faults can cause continuous operation.
Possible Causes
Dirty condenser coils reducing heat dissipation
How to Identify: Dusty/dirty coils visible at rear or beneath unit, compressor hot, increased runtime
Part: Condenser coils
Dirty or leaky door seals (gasket) allowing warm air entry
How to Identify: Cold air visibly escaping, failed ‘dollar bill test’ between seal and frame
Part: Door gasket/seal
Inefficient or failing compressor
How to Identify: All other components test good but compressor still runs continuously, unusual noise or heat
Part: Compressor
DIY Solutions
Clean condenser coils
- Unplug refrigerator.
- Slide out fridge and locate condenser coils.
- Use vacuum/brush to remove dust and debris.
- Slide fridge back and plug in.
Inspect and fix door seals
- Check door seal with dollar bill test.
- Clean seal with soapy water.
- Replace gasket if cracked or fails seal test.
Adjust/verify temperature settings
- Set refrigerator to recommended 37°F and freezer to 0°F.
- Monitor compressor behavior over a day.
Check for frost buildup and defrost
- Unplug fridge and empty freezer.
- Remove access panel and inspect coils.
- If frosted, allow controlled defrost.
- Reassemble and test.

Common Issues Reported by Users
- Faulty thermostat preventing the compressor from cycling off
- Dirty condenser coils causing overheating and continuous running
- Refrigerant leak leading to inefficient cooling and compressor running constantly
User Suggested Solutions
-
Check and replace the thermostat if faulty. Locate the thermostat inside the refrigerator, disconnect the power, and test the thermostat with a multimeter. If it shows no continuity, replace it with a new one.
-
Clean the condenser coils. Unplug the refrigerator, locate the coils (usually at the back or beneath), and use a vacuum or brush to remove dust and debris. Plug the refrigerator back in and monitor the compressor.
-
Check for refrigerant leaks. Inspect the refrigerant lines for any signs of damage or leaks. If a leak is found, it is recommended to call a professional to repair and recharge the refrigerant.
