The “read temp sensor failed” error on Bitmain Antminer S17+ ASICs can frustrate miners. Temperature sensors play a crucial role in monitoring the temperature of the ASICs and ensuring they don’t overheat. When the temperature sensors fail, it can cause the hashboard to stop working and the miner to stop running. In this troubleshooting guide, we will provide you with a step-by-step guide on how to fix the “read temp sensor failed” error on Bitmain Antminer S17+ ASICs. We will cover various methods, including checking the physical connections of the temperature sensors, updating the firmware, and testing the temperature sensor chip. These steps will help you resolve the issue and get your miner back up and running.

Possible causes of the read temp sensor error

Bitmain Antminer S17+ ASICs can encounter the “read temp sensor failed” error for various reasons affecting the hash board’s performance and stability. High temperature can make the miner shut down or malfunction, while a faulty data cable can prevent communication between the hash and control boards. Additionally, the wrong temp sensor type can result in incorrect temperature readings, and incompatible firmware can cause conflicts and glitches with the hardware. Different solutions can be applied to fix this error depending on its cause and severity. Rebooting the miner or using recovery firmware can resolve minor issues and glitches while flashing the latest firmware or installing a non-Bitmain firmware can update the miner with new features and customization options. However, before attempting any repairs on the miner, following safety precautions and warnings is crucial to prevent damage and ensure safety. This includes avoiding electrostatic discharge, wearing protective gloves and goggles, and disconnecting the power supply before touching any components to avoid electric shock and short circuits.

Troubleshooting Steps to fix “read temp sensor failed” on Bitmain Antminer S17+ ASICs

  1. Look for “read temp sensor failed” or “can’t get enough hashrate reg val” messages in the kernel logs.
  2. Check all the physical connections of the temperature sensors to ensure they are correctly connected. A loose or poorly connected sensor can sometimes trigger the “read temp sensor failed” error.
  3. Reboot the miner and check if the issue resolves itself. Sometimes, a simple reboot can fix the problem.
  4. If restarting the miner doesn’t work, reset it to its default settings. To do this, log in to the miner’s control panel and navigate to the “System” tab. Click on the “Reset Config” button and then confirm the action. This will reset the miner to its default settings.
  5. If resetting the miner doesn’t work, try updating the firmware. You can find the latest firmware for the Antminer S17+ on the Bitmain website. Download the firmware and follow the instructions to update the miner.
  6. If none of the above steps work, there may be a hardware issue with one or more temperature sensors. Check the backstage kernel log to see if the temperature sensor chip is faulty. If it is, you may need to replace it. If you’re not familiar with hardware repair, it’s best to contact Bitmain support or a professional technician for assistance.
  7. If the temperature sensor chip is not faulty, the issue could be with the data cable. Swap the data cable of the Antminer S17+ hashboard that is not shown with the data cable of the normal hashboard (only the hash board is replaced), and first eliminate the problem of the cable and the Antminer S17+ control board.
  8. Measure the voltage and resistance of the corresponding chip, and compare the measured resistance with other hash boards of the same type or good hash boards. If the temperature sensor chip is normal, the chip through which the temperature sensor circuit will pass may be abnormal.
  9. Use a fluke 15b+ multimeter in DC gear and diode gear, connect the red test lead to the corresponding heat sink and test with the black test lead. Compare the measured chip data with the standard chip data. If an abnormality is found, replacing the abnormal chip directly is recommended.
