Antminer T15 hash board common faults and solutions

The following faults come from the T15 test fixture. When this phenomenon occurs, it can be eliminated according to the following methods.

Fault 1: The single hash board test fixture log shows "Pattern NG";

When "Pattern NG" appears, it means that the hash rate of one or several ASIC chips is low, thus affecting the overall hash rate of the hash board.

According to the log, the hash rate of No.2, No.3, and No.50 ASIC chips are low, and it is recommended to replace No. 2/3/50 ASIC chips directly.

Fault 2: The single hash board test fixture log shows "Sensor NG";

When the test fixture log shows "Sensor NG, " the hash board temperature sensing circuit is faulty.

According to the log, ASIC chips No.11/15/41/45 can be re-soldered. However, if the problem cannot be solved after re-soldering, it is recommended to replace them directly.
