Zero hash rate solution for S19 miners

When the S19 miners run for a long time, there may be a phenomenon of 0 hash rate. How should the miners solve this problem? We have found the following solutions for this fault, hoping to help you.

1. Zero hash rate caused by high-temperature protection mode

When the miner's temperature turns red (as shown in the figure below), it means that the miner is in high-temperature protection mode. In this mode, all power supplies of the hash board will be cut off, and the miner will have zero hash rate.

Solution: Check whether the temperature is too high during operation and whether the heat dissipation is normal.

2. Fan failure leads to zero hash rate

When the fan speed of the miner is obviously abnormal, it is usually a functional failure of the fan. When the fan fails to function correctly, all power to the hash board is cut off, and the miner becomes zero hashrate. When the miner is restarted or turned on, the function of the fan is checked; if the fan is broken, the miner will not be able to start, resulting in no hash rate.

Solution: Generally, the fan cable needs to be reconnected. If it still doesn't work, the fan needs to be replaced.

3. PSU abnormality leads to zero hash rate

When the miner detects that the PSU is abnormal, it will not supply power to the hash board, causing the miner to fail to boot. Therefore, if the PSU is abnormal, you need to check whether the data log shows the error code V:1 to identify whether there is an abnormality in the PSU.

Solution: Reconnect the cable of the PSU; if it still doesn't work, please replace the PSU.

4. Network or pool error

When the miner cannot connect to the network or cannot connect to the mining pool, the miner cannot be activated, resulting in no hash rate.

Solution: Check the settings of the mining pool. If the settings are normal, you need to check the network problems. Due to the different mining farm network constructions, relevant professional network technicians must troubleshoot.

5. Hash board failure

There are many kinds of hash board failures, especially if the ASIC IC on the hash board is lower than the design, the hardware version on the hash board is abnormal, PIC error, temperature error, EEPROM error, etc., the miners will cut off the power supply to the hash board, This will result in zero hash rate. Zero hash rate also happens when all 3 hash boards are not detected.

Solution: Generally, it needs to be sent to the nearest repair center for repair.
