How to Repair Chiller Freezer That’s Not Cooling?

 

If you’ve ever encountered the issue of your commercial refrigerator or display chiller not cooling, it can be frustrating, especially when it disrupts your business operations. Understanding how to troubleshoot and repair these issues is critical to avoiding significant losses. Here’s a comprehensive guide on how to repair a commercial refrigerator when it’s not cooling, with essential tips for restaurant and retail business owners.

 

1. Overloading the Chiller Freezer

 

One of the most common causes of cooling problems is overloading the commercial refrigerator or display chiller. When you place too many items inside, the doors may not seal properly, leading to warm air entering the unit. This compromises the cooling capacity, causing the internal temperature to rise and resulting in poor refrigeration performance. It can also lead to higher energy consumption, as the refrigerator works harder to cool down. Ensure that the doors are fully closed and that items are not blocking the door seals.

 

2. Manual Defrosting Issues

 

For refrigerators and chiller freezers without automatic defrost functions, ice buildup over time can block the cold air flow. If the frost layer becomes too thick, it can hinder the heat exchange, making it difficult for the refrigerator to maintain the desired temperature. For manual defrost units, it is essential to defrost them regularly to prevent frost accumulation.

 

Even for refrigerators equipped with automatic defrosting systems, it’s advisable to inspect the evaporator for ice buildup. If the evaporator has excessive frost, the cooling process can be compromised. In such cases, manually removing the ice and checking the defrost timer or heater is a good idea.

 

3. Incorrect Temperature Settings

 

Another potential cause of refrigeration failure could be incorrect temperature settings. If the commercial refrigerator or chiller fridge is not reaching the set temperature, this could point to an issue with the thermostat. A faulty thermostat might prevent the refrigerator from reaching the desired cooling level. On the other hand, if the temperature is achieved but the refrigerator keeps running without stopping, it may be due to compressor overheating or a faulty temperature control system.

 

4. Compressor Problems

 

The compressor is the heart of any commercial refrigerator. If the compressor is malfunctioning, the refrigerator won’t cool properly. One common issue is refrigerant (also called “snow oil” or Freon) leakage, which can prevent the compressor from effectively cooling. You can identify this problem by feeling the compressor or valves for unusual heat levels or listening for irregular sounds.

 

Additionally, if the compressor is not running but the unit is still powered on, it may be a result of an electrical issue, such as a broken thermostat or a damaged relay switch. In any case, troubleshooting the compressor should only be done after disconnecting the unit from the power source to avoid any potential hazards. If compressor problems persist, it’s best to contact a professional technician for assistance.

 

5. Professional Repair and Maintenance

 

When a commercial refrigerator or chiller freezer is not cooling properly, diagnosing the issue is the first step, but it’s essential to know when to call in a professional. Some issues, like refrigerant leaks or electrical faults, require specialized equipment and expertise to repair. Regular maintenance can also help prevent these issues, such as cleaning the condenser coils, checking refrigerant levels, and inspecting door seals for wear and tear.
