Commercial True Refrigerator Error Code LA or lo
If you encounter the error code “LA” or “lo” on your Commercial True refrigerator, it signifies a low-temperature alarm. This means the temperature inside the refrigerator has dipped below the set point, raising concerns about the proper preservation of your food and beverages.
Several factors can contribute to this issue, and addressing them promptly is crucial to maintain optimal food safety and prevent spoilage. Here’s a breakdown of the potential causes and DIY solutions you can explore:
1. Malfunctioning Thermostat:
The thermostat is responsible for regulating the temperature within the refrigerator by turning the compressor on and off as needed. A malfunctioning thermostat might send incorrect signals, causing the compressor to over-cool, leading to excessively low temperatures. While attempting to repair a thermostat yourself isn’t recommended due to the risk of improper calibration, you can try resetting it. Consult your True refrigerator’s manual for specific instructions on resetting the thermostat. If the issue persists, it’s advisable to contact a qualified appliance repair technician for professional diagnosis and repair.
2. Faulty Defrost Timer:
The defrost timer initiates and controls the defrost cycle, periodically melting frost buildup on the evaporator coil. If the defrost timer malfunctions and extends the defrost cycle, it can lead to excessively low temperatures inside the refrigerator. Similar to the thermostat, repairing the defrost timer yourself isn’t recommended due to its intricate functionality. You can try resetting the defrost cycle by consulting your True refrigerator’s manual. However, if the issue persists, contacting a qualified appliance repair technician is crucial.
3. Sensor Issue:
The refrigerator relies on various sensors to monitor temperature at different points. A faulty temperature sensor can send inaccurate readings to the control board, causing the compressor to run excessively and leading to excessively low temperatures. Unfortunately, diagnosing and repairing a faulty sensor is beyond the scope of DIY solutions due to the specialized tools and expertise required. Contacting a qualified appliance repair technician for proper diagnosis and repair is essential.
4. Other Potential Causes:
- Door left ajar: Ensure the refrigerator door is closed properly and forms a complete seal. Even a minor gap can allow cold air to escape, causing the temperature to drop.
- Excessive door openings: Frequent opening and closing of the door can introduce warmer air, requiring the compressor to work harder to maintain the set temperature. Minimize door openings and maintain proper organization to avoid blocking airflow vents.
- Refrigerator overloaded: Overcrowding the refrigerator can impede proper air circulation and prevent the cold air from reaching all areas effectively. Ensure adequate space between items to allow for efficient air flow.
Remember: While these DIY solutions might offer temporary relief, it’s crucial to emphasize consulting a qualified appliance repair technician for professional diagnosis and repair, especially if the issue persists or you’re uncomfortable troubleshooting the appliance yourself. They possess the expertise and tools to accurately identify the root cause of the low-temperature alarm and ensure your Commercial True refrigerator functions optimally.
