Commercial True Refrigerator Fans running but not cooling

Your Commercial True refrigerator is running, but it’s not cooling properly. The fans are running, but the temperature inside the unit remains high.

There are several possible causes for this issue:

1. Dirty condenser coils: The condenser coils are located on the back or bottom of the refrigerator. They dissipate heat from the refrigerant, allowing the refrigerator to cool. If the coils are dirty, they can’t dissipate heat effectively, which can lead to cooling problems.
2. Faulty compressor: The compressor is the heart of the refrigeration system. It circulates the refrigerant throughout the system, absorbing heat from inside the refrigerator and releasing it outside. If the compressor is faulty, it can’t circulate the refrigerant properly, which can lead to cooling problems.
3. Defrost system malfunction: The defrost system prevents ice from building up on the evaporator coils. If the defrost system malfunctions, ice can build up on the coils, blocking airflow and preventing the refrigerator from cooling properly.
4. Refrigerant leak: A refrigerant leak can cause the system to lose pressure, which can lead to cooling problems.
5. Evaporator fan motor failure: The evaporator fan motor circulates air inside the refrigerator, helping to distribute cold air evenly. If the fan motor fails, the air inside the refrigerator will not circulate properly, which can lead to cooling problems.

There are a few things you can try to fix this issue yourself:

1. Clean the condenser coils: Use a brush or vacuum cleaner to remove any dirt or debris from the condenser coils.
2. Check the compressor: If the compressor is not running, check the power supply to the refrigerator. If the compressor is running but making strange noises, it may be faulty and need to be replaced.
3. Check the defrost system: If the defrost system is not working properly, you may need to replace the defrost timer, heater, or thermostat.
4. Check for refrigerant leaks: If you suspect a refrigerant leak, you will need to call a qualified technician to repair the leak.
5. Check the evaporator fan motor: If the evaporator fan motor is not running, you may need to replace the motor.

To prevent this issue from happening in the future, you can:

• Regularly clean the condenser coils: Clean the coils at least once every three months.
• Have the refrigerator serviced regularly: A qualified technician can check the compressor, defrost system, and other components for any potential problems.
• Look for signs of a refrigerant leak: If you notice a decrease in cooling capacity, a hissing sound, or frost formation around the refrigerant lines, call a qualified technician to repair the leak.

If you have tried the DIY solutions and the problem persists, you will need to call a qualified technician to repair the refrigerator.
