Troubleshooting for Antminer S19 Series Control Board


This post troubleshoots for the Antminer S19 Series control board. When the Antminer S19 Series miners have the following problems, you need to consider shipping the control board back for repair.

Case 1: the Miner Cannot Get IP

There are two cases,

1. The new miner cannot get the IP address

Use the method in the following link to return to factory settings after first making sure the DHCP mode of the network has been enabled, routers, and network cables are in working order.

The control board needs to be sent back for repair if it still isn’t working.

2. After changing the network, the miner cannot get the IP address

Changing the IP or going back to factory settings may help you get the new IP if the miner is configured with a static IP; if not, please see 1.

Case 2: the Miner Power Off During the Upgrading Process

Recharge the miner, and if that doesn’t help, try the approach described above.

Case 3: the Hash Board Cannot Be Detected

Replace the miner’s control board with a well-known control board from another miner if it can only detect two or three hashboards. If the problem persists, it means the hashboard(s) is/are damaged; send the control board back for repair.

Case 4: the Miner Cannot Detect the Fan

Replace any bad fans with good ones if the miner can only detect one fan or cannot detect any fans at all. If the problem persists, swap the miner’s control board with another miner to check whether the control board’s fan port has been damaged. If so, send the control board back for repair.
