A refrigerator that runs but doesn’t cool is a common issue reported in many Appliance Repair San Diego cases. The unit may sound normal, and the lights might work, but the food inside remains warm. If this happens, it’s important to act fast to avoid food spoilage and higher repair costs.
Technicians offering Appliance Repair San Diego often trace this problem to a few specific causes. The good news is that some of them are easy to check before calling a professional. Start by inspecting the condenser coils. These are usually located behind or beneath the refrigerator. If they are covered in dust or pet hair, the cooling system can’t release heat properly. Use a vacuum or brush to clean them.
Next, check the evaporator fan. This fan circulates cold air throughout the refrigerator and freezer. If the motor is faulty or the blades are blocked, the fridge may run but not cool. Open the freezer and listen for the fan. If you don’t hear it, the part may need replacement.
Another possible cause is a problem with the start relay. This small device helps the compressor start. If it fails, the compressor may not run correctly even though the fridge seems active. Unplug the unit and test the relay for continuity using a multimeter. If it’s defective, replace it.
Make sure the temperature settings are correct. Sometimes, someone may accidentally change the dial or press a button. Set the refrigerator to around 37°F (3°C) and the freezer to 0°F (-18°C). Wait a few hours to see if cooling improves. Avoid overloading the fridge, as poor airflow can also affect cooling.
Inspect the door seals. If they are cracked, loose, or dirty, cold air may escape, causing the fridge to work harder without success. Close the door on a piece of paper and try to pull it out. If it slides out easily, the seal may need replacing.
If all these parts seem fine and the refrigerator still doesn’t cool, the compressor might be failing. This is a more serious issue and usually requires a trained technician. Compressors are costly and difficult to replace without proper tools and knowledge.
In many cases, calling an expert in Appliance Repair San Diego can save time and prevent bigger damage. Technicians can quickly test components and make repairs using the right parts. Delaying service could result in more expensive fixes or the need for a new appliance.
To keep your refrigerator running properly, clean the coils twice a year and avoid blocking air vents inside. Regular checks on seals, settings, and fan noise can also help catch issues early. Simple maintenance and quick action can make a big difference in appliance performance and energy use.
