The Bitmain Antminer KA3 is Unstable

Find out why your Bitmain Antminer KA3 restarts itself and how to fix it if the hashrate is unstable.

Abnormal Performance

1. The Bitmain Antminer KA3 restarts automatically
2. The hashrate is unstable

Reasons and Solutions

1. Because it is an electronic device, the Bitmain Antminer KA3 is susceptible to electromagnetic interference. The miner might restart if the control signal is disrupted. When the chip is interfered with, the chip or hash board may behave abnormally. Restarting usually restores it, and grounding and shielding can help prevent it from happening.
2. The electricity supply is erratic. When the Bitmain Antminer KA3 is operating, the current of the hash board’s power output can reach 200–300A, and the power output for the miner with liquid cooling is higher. The hash board will restart when the power output varies significantly, which is difficult to notice. You can usually try to replace the power supply.
3. The voltage is low or the voltage is unstable. You’ll need specialized tools or an experienced electrician to check for this issue.
4. The control panel is harmed. The control board is the center of the miner, which is equivalent to a microcomputer. Firmware programs are stored in flash memory. It will also force the miner to restart when the control board is abnormal. Generally, it can be restored to the factory settings .
5. In general, the chip can be located by querying the log, but it is unstable. It is possible to directly return to the factory for repair if the chip is unstable or lost.
6. Because of the network’s instability, there is a chance that the Bitmain Antminer KA3 will restart. In general, you can try changing the network cable or network port for local inspection.
