How to replace the damaged Avalon 1166 pro hash board?

With its excellent fully optimized performance and adaptability to varying mining environments, Canaan Avalonminer 1166 pro has gained widespread recognition. However, as the miner operates at high speed for a long time, wear or malfunction of core components such as the hash board becomes a non-negligible issue. Replacing a new hash board for Avalon 1166 Pro can quickly resolve the problem of hash rate decrease, ensuring its continuous mining, thus effectively safeguarding miners' income.

Factors such as high temperature, unstable voltage, and long-term continuous operation can damage the hash board. If the miner experiences a low hash rate or 0 hash rate, it may be caused by a corrupted hash board. In this case, we should immediately detect and replace the faulty one to quickly restore the normal operation of the miner, avoiding further losses.

Here are the replacement steps for Avalon 1166 pro hash board:

1. Power off the miner, then disconnect the power cord from the power socket. Wait for a few minutes to allow the machine to cool down, avoiding burns during the operation.

2. Unplug the fan connector, remove the protective cover plate above the control board.

3. Locate the connecting cables between the hash board and the control board, then gently unplug them. After that, unscrew the fixing screws of the conductive copper sheets.

4. Dismantle the outlet fan, then take out the faulty hash board that needs to be replaced.

5. Check if the new Avalon 1166 Pro hash board is intact. Then, insert it into the original position along the card slot, ensuring that it fits perfectly with the slot.

6. Tighten the fixing screws of the conductive copper sheets, reconnect the previously unplugged cables, and ensure that the connections are secure.

7. Install the air outlet cooling fan, align the protective cover plate with the screw holes, tighten the nuts.

8. Plug the fan connector into the corresponding port, and the replacement is complete.

9. Power on the miner to observe its operation, and confirm if the hash rate has returned to normal level through its backend logs.

In the field of digital currency mining, the stability of miner performance is directly related to their income. Timely replacement of the faulty hash board can quickly restore the optimal hash rate of the machine, maximizing mining revenue.
