Find the reasons and solutions if your Bitmain Antminer L3+ and Antminer L3++ miners restarts automatically or the hashrate is unstable.
The Bitmain Antminer L3+ and Antminer L3++ are two popular models of Bitmain Antminer L3 series. Try the methods below if your miners keep restarting themselves or if the hashrate is unstable.
Abnormal Performance
- The Bitmain Antminer L3+/L3++ restarts automatically
- The hashrate is unstable
Reasons and Solutions
- Interference. The Bitmain Antminer L3+/L3++ is an electronic product and is sensitive to electromagnetic interference. When the control signal is interfered, the miner may restart. When the chip is interfered with, the chip or hash board may behave abnormally. In most cases, it can be repaired after restarting and avoided by grounding and shielding.
- The power supply is unstable. When the Bitmain Antminer L3+/L3++ is operating, the power output of the hash board can reach 200–300A, and the power output for the liquid cooling miner is higher. It is difficult to tell when the power output varies significantly because it will restart the hash board. As a general rule, you can try changing the power supply.
- Low or unstable voltage are the circumstances. You need specialized tools or an experienced electrician to check for this issue.
- The control board is damaged. The control board is the center of the miner, which is equivalent to a microcomputer. The firmware programs are stored in the flash memory. The control board malfunction will also force the miner to restart. In most cases, the factory settings can be restored.
- The chip is unstable. Generally, it can be found by querying the log. The chip is broken or unstable; it can be sent back to the manufacturer for immediate repair.
- The network is unstable, and there is a certain probability that the Bitmain Antminer L3+/L3++ will restart. You can typically try switching the network cable or network port for local inspection.
