Read temp sensor failed issue on Bitcoin mining hardware

In the world of Bitcoin mining, ensuring that your hardware is running smoothly is crucial for optimal performance. One common issue that miners may encounter, particularly those using the Antminer T17/S17 series, is the “read temp sensor failed” error.

This error typically indicates a problem with the temperature sensor in the mining hardware. The temperature sensor plays a vital role in monitoring the heat levels of the hardware to prevent overheating and potential damage. Therefore, when the system fails to read the temperature sensor, it can lead to significant issues, including decreased mining performance or even hardware failure.

Understanding this error, its causes, and how to troubleshoot it is essential for anyone using the Antminer T17/S17 series for Bitcoin mining. In the following sections, we will delve deeper into this issue, providing a comprehensive guide on how to address and prevent it.

Problem Description

The error message associated with this issue typically reads as follows: “temperature.c:697:get_temp_info: read temp sensor failed: chain = 1, sensor = 0, chip = 64”. This message might seem complex at first glance, but it provides valuable information about the nature of the problem.

The “temperature.c:697:get_temp_info” part of the message refers to the specific function within the miner’s firmware that is encountering the issue. This function is responsible for retrieving the temperature information from the sensor.

The “read temp sensor failed: chain = 1, sensor = 0, chip = 64” part of the message provides more specific details about the problem. It indicates that the system failed to read the temperature sensor on a specific chain (chain = 1) and chip (chip = 64).

In essence, this error message indicates that there’s a problem with the temperature sensor in the mining hardware. The system is unable to retrieve the temperature information, which is crucial for monitoring the hardware’s heat levels and preventing overheating.

Common Solutions

When faced with the “read temp sensor failed” error, there are several common methods that you can try to fix the issue:

1. Reboot the Miner: The simplest solution is to reboot the miner. Sometimes, a simple reboot can help the system to reset and correct any minor glitches that might be causing the error.
2. Use the Recovery Firmware on the Miner’s SD Card: If a reboot doesn’t solve the issue, you can try using the recovery firmware that is stored on the miner’s SD card. This firmware is a backup of the system’s original settings and can help to restore the miner to its default state.
3. Flash the Latest Firmware: Another solution is to flash the latest firmware onto the miner. Firmware updates often include fixes for known issues, so updating to the latest version could potentially resolve the problem.
4. Use the Recovery Firmware and then Flash the Latest Firmware: If using the recovery firmware or flashing the latest firmware individually doesn’t work, you can try using them in combination. First, use the recovery firmware to restore the miner to its default state. Then, flash the latest firmware onto the miner.
5. Install a Non-Bitmain Firmware: If none of the above solutions work, you might consider installing a non-Bitmain firmware. Some users have reported success with this method. However, please note that this should be considered a last resort, as it may void your warranty and could potentially cause other issues if not done correctly.

Remember, it’s important to follow all instructions carefully when implementing these solutions, and always ensure that your miner is powered off and unplugged before performing any hardware modifications.

Sensor Replacement

In many cases, if the “read temp sensor failed” error persists after trying the above solutions, it may be necessary to replace the temperature sensor itself. This is because the error message often indicates a hardware issue with the sensor, which software fixes may not be able to resolve.

It’s important to note that while the above remedies can sometimes fix the issue, their success rate is not particularly high when it comes to this specific error. This is likely due to the fact that the problem is often rooted in a hardware malfunction, which software solutions are unable to address.

Replacing the temperature sensor is a more direct approach to resolving the issue. However, it should be undertaken with caution, as it involves manipulating the hardware components of the miner. If you’re not comfortable with this, it’s recommended to seek professional help.

Sensor Locations & Sensor Part Number

Understanding the location of the temperature sensors in your mining hardware can be helpful when troubleshooting the “read temp sensor failed” error. In the newer models of Antminer, there are typically four temperature sensors. These sensors are located near chip 9, chip 7, chip 22, and chip 24 on an Antminer T17, as an exemple.

Interestingly, the placement of these sensors follows a specific pattern. They are always located around the third column of the miner, with two sensors positioned above and two below. This arrangement is consistent, regardless of the exact model of the miner.

Being aware of the sensor locations can help you better diagnose and address the issue. For instance, if you’re receiving an error message related to a specific sensor, you can check its location and inspect it for any visible signs of damage or malfunction.

When it comes to replacing the temperature sensor, it’s crucial to know the exact part number to ensure compatibility with your mining hardware. The temperature sensor used in Antminer models typically has the part number TMP451AIDQFR.

Knowing the part number is especially useful if you’re ordering a replacement sensor. It allows you to ensure that you’re getting the correct part, which is essential for the proper functioning of your mining hardware. Always double-check the part number before making a purchase to avoid any potential issues with compatibility.

Sensor Replacement Process

Replacing the temperature sensor in your mining hardware can be a complex process, requiring a certain level of technical knowledge and expertise. Unfortunately, as of now, there’s no readily available information or detailed guide on how to replace the sensors in Antminer models.

This lack of information can make the process challenging for those who are not familiar with hardware repair. It’s important to approach this task with caution, as improper handling of the hardware components can lead to further damage.

If you’re not comfortable with performing the replacement yourself, it’s highly recommended to seek professional help. A professional can ensure that the replacement is done correctly and safely, preventing any potential issues.

Conclusion

Understanding and troubleshooting the “read temp sensor failed” error is crucial for maintaining the performance and longevity of your Bitcoin mining hardware. In this article, we’ve explored what this error means, how to identify it, and various methods to fix it, including rebooting the miner, using recovery firmware, flashing the latest firmware, and even installing a non-Bitmain firmware.

However, it’s important to note that these solutions may not always be successful, as the issue often stems from a hardware malfunction. In such cases, replacing the temperature sensor may be necessary. Unfortunately, there’s currently a lack of detailed information on how to perform this replacement, highlighting the need for continued community effort and knowledge sharing to solve this issue.
