Troubleshooting Thermo King Code 35
When encountering a Thermo King code 35 error, it is essential to follow a systematic troubleshooting approach to identify and resolve the underlying issue. By understanding the possible causes and taking the necessary steps, you can effectively troubleshoot and fix the Thermo King code 35 error.
- Check the Relay Board: Begin by inspecting the relay board for any signs of corrosion or broken circuits. These issues can disrupt the functioning of the run relay circuit and trigger the code 35 error. If you encounter any corrosion or broken circuits, it may be necessary to repair or replace the relay board.
- Tap the K9 Relay: In some cases, tapping the K9 relay on the board can temporarily revive it and resolve the code 35 error. Give the relay a gentle tap and observe if it helps restore the functionality of the unit. However, keep in mind that this is merely a temporary solution and further repairs may be required.
- Check the Alternator: The alternator’s compatibility with the unit’s software can also contribute to a code 35 error. If the alternator is incompatible and does not meet the required current draw, a software update may be necessary. Consult the manufacturer’s guidelines and inquire about available updates to address this issue.
- Inspect Wiring, Fuses, and Sensors: The run relay circuit is interconnected with various components such as wiring, fuses, and sensors. Examine these elements thoroughly to ensure they are in proper working condition. Replace any damaged or faulty wiring, fuses, or sensors that may be causing the code 35 error.
- Check Fuel Pump and High Pressure Cutout: Another crucial step in troubleshooting the code 35 error is to verify the voltage levels of the fuel pump and high-pressure cutout. Insufficient voltage to these components can result in the code 35 error. Ensure that the power supply is adequate and resolve any voltage-related issues to resolve the error.
By following these troubleshooting steps, you can effectively diagnose and address the Thermo King code 35 error. However, it is important to remember that complex issues may require professional assistance. If the problem persists or if you are unsure about performing these tasks yourself, it is recommended to consult a certified technician or Thermo King service provider for further guidance.
Repairing Thermo King Code 35
To repair a Thermo King code 35 error, it’s important to address the potential causes mentioned earlier. If you find that the relay board is defective, you may need to replace or repair it. It’s common for these boards to experience corrosion, but simply replacing the faulty relays often resolves the problem.
If the alternator is incompatible with the software of the unit, a software update may be necessary. It’s crucial to ensure that the wiring, fuses, and sensors associated with the run relay circuit are in good condition. Additionally, fixing any issues with the fuel pump and high-pressure cutout voltage can help resolve the code 35 error.
By following these steps and addressing these components, you can successfully repair the Thermo King code 35 error and get your refrigeration unit back on track.
