The diagnosis and processing for the KA3 log are shown here.
- Power Failure
If the log indicates that three computing boards are unable to locate the chip and the majority of the power supplies on the computing boards have output issues, you can check to see if the power supply’s copper row screws are loose or you can replace the power supply.
- Fan Failure
If the log prompted “sweep error string = F:1” that is, the fan is abnormal, you can try to replace them one by one with a normal fan, and then replace them after confirmation.
- Drop Board Failure
KA3 has 3 computing boards (chain=0, chain=1, chain=2); if less than 3 are found, that is, if there are fewer boards, the row of wires can be disconnected, re-plugged, and checked to see if the power supply copper row screws are loose; if not, it is advised to return for repair.
- High Temperature Failure
If the log indicates “poweroff=true msg=”high temp 1 low temp fan err 0 read no temp 0, uneffective temp 0, lost connection too long 0″” is high temperature protection, you can reboot to recover (before rebooting, you need to check whether the operating environment temperature of the mining machine is too high, whether there are foreign objects blocking the air inlet of the mining machine, and whether the ventilation is normal to avoid repeated high temperatures leading to damage to the mining machine).
- Mining Pool Anomalies
If the logs indicate “No servers could be used”, it means the pool is abnormal, you need to check if the pool settings are wrong, you can change the pool or contact the mining pool to solve the problem.

I have ka3 antiminer showing abnormal chips after 30 minutes or running, can you help me by explaining this error please? Thanks!
Sweep error string = J0:1
First, thanks for reading our blog!
The “J0:1” error string on your ka3 Antminer indicates a problem with the ASIC chips on your miner. It means that one or more of the chips are not functioning correctly or have become defective, leading to the abnormal behavior you are experiencing.
When the miner is running, it performs various operations, including hashing, and if any of the ASIC chips are not working correctly, it can cause the device to malfunction or display errors. This error can occur due to various reasons, such as a faulty chip, insufficient cooling, or improper power supply.
To resolve this issue, you can try the following steps:
Check the power supply: Ensure that your Antminer is receiving enough power and that the power supply is working correctly.
Check the cooling: Ensure that the Antminer is receiving sufficient cooling. Overheating can cause the ASIC chips to malfunction or fail. Make sure that the fans are working correctly, and that the temperature inside the miner is within the acceptable range.
Inspect the ASIC chips: Check the ASIC chips for any visible damage, such as cracks or burn marks. If any chips are damaged, you may need to replace them.
Reset the Antminer: Sometimes, a simple reset can resolve the issue. Try resetting the Antminer to its default settings.
Update firmware: Updating the firmware on the Antminer can also help resolve any software-related issues that may be causing the problem.
Youcan check our BuyantminerKA3.com to get the latest firmware and get more information about Antminer KA3.
If none of the above steps work, you may need to contact the manufacturer or a professional technician for further assistance. They can help diagnose the issue and provide a solution.
It’s important to note that attempting to repair or modify the Antminer yourself may void the warranty and cause further damage. So, if you are not familiar with the hardware or the technical aspects of mining, it’s best to seek professional help.
