- Code 26 often accompanies code 32 and signifies poor cooling.
- Check the refrigerant charge and replenish if it’s low.
- Inspect the evaporator coil sensor, control return air sensor, and control discharge air sensor.
- Monitor the temperature manually and report any alarms at the end of the day.
Troubleshooting Thermo King Reefer Code 32
In the world of reefer units, the Thermo King SL3000 is a reliable and popular choice. However, like any mechanical system, it can encounter issues from time to time. Two common alarm codes that may appear on the SL3000 unit are code 26 and code 32. Understanding the causes and troubleshooting these alarm codes is crucial for maintaining the optimal performance of your Thermo King reefer.
Alarm code 26 is an indicator of a problem with the electric motor. This can result from various issues such as motor overload, abnormal voltage, or a faulty motor. If you encounter this alarm code, it is recommended to check the motor’s connections and wiring for any loose or damaged parts. Additionally, assessing the voltage input and ensuring it falls within the manufacturer’s specified range is essential. If the issue persists, contacting a professional technician for further inspection and repair is advisable.
Alarm Code 32: Low Refrigeration Capacity
Alarm code 32 points to low refrigeration capacity, indicating that the reefer unit may struggle to maintain the desired cooling temperature. To address this alarm code, several troubleshooting steps can be taken.
- Check the refrigerant charge: Insufficient refrigerant can lead to reduced cooling capacity. It is important to ensure the refrigerant levels are within the recommended range. If the charge is low, it should be replenished by a qualified technician.
- Inspect the evaporator coil sensor: The evaporator coil sensor plays a crucial role in determining the temperature and regulating the cooling process. If it is malfunctioning, inaccurate temperature readings can occur. Check for any sensor damage or wiring issues that may affect its performance.
- Examine the control return air and control discharge air sensors: These sensors monitor the airflow and temperature within the reefer unit. Faulty or damaged sensors can disrupt the cooling process and trigger alarm code 32. Inspect these sensors for proper functioning and address any issues accordingly.
