To troubleshoot and resolve Thermo King Code 26, consider the following key elements:

1. Heat Circuit:

  • Ensure the heat circuit is functioning correctly. Faulty components or sensors in the heat circuit can trigger this error.

2. Discharge Air Sensor:

  • Check the discharge air sensor for proper functioning. A malfunctioning sensor can lead to inaccurate temperature control and trigger Code 26.

3. Auto Switch from Diesel to Electric:

  • Examine the automatic mode transition of the system from diesel to electric. Errors may arise from issues with this switching mechanism.

4. High-Pressure Cut and High Discharge Pressure:

  • Pay attention to high-pressure situations. Code 26 and alarms may sound when the refrigeration system is under high pressure. Verify the proper operation of high-pressure cut-off systems.

5. Vapor Motor and Engine Issues:

  • Investigate any problems with the vapor motor and engine. If they fail to start or experience issues, it can lead to error codes.

6. Suction Line Solenoid and Liquid Line Solenoid:

  • Check the solenoids in the suction and liquid lines. Issues with these components can affect temperature control and trigger alarms.

7. Receiver Tank Pressure Solenoid:

  • Ensure that the receiver tank pressure solenoid is functioning properly. Malfunctions can disrupt the refrigeration cycle and lead to errors.

8. Evaporator Coil Temperature Sensors:

  • Examine the coil’s inlet and outlet temperature sensors and other sensors on the evaporator coil. Alarms and temperature readings that are not accurate can result from issues with these sensors.

9. Remote Fan Speed:

  • Monitor the remote fan speed control. Inconsistent or incorrect fan speeds can result in alarms.

10. Multiple Alarms:

  • Keep in mind that there might be other alarm codes in addition to Code 26. Methodically handle several alarms to find and fix the problem’s core cause.

11. Evaporator Coil Outlet Temperature Sensor:

  • Pay attention to the temperature sensor controlling the evaporator coil outlet. Accurate temperature control relies on these sensors functioning correctly.

Examining the heat circuit, sensors, solenoids, and pressure control systems are all necessary steps in proper troubleshooting. By quickly resolving problems, you can minimize downtime and product spoiling while ensuring the dependable operation of your Thermo King unit.

Repair the error ASAP or report the issues right away, whether Thermo King code 17 or Thermo King code 26.
