If your Avalon 1126 pro miner cannot continue to work normally after running for a while, you can first consider whether its hash board is faulty. When the hash board fails, the miner's hash rate will be lower than the normal hash rate. Therefore, the faulty hash board should be checked in time and replaced with a new one to ensure the miner's normal operation and profit. The quality of all our products is guaranteed, and each product is strictly screened to ensure that the product can normally work after receiving the goods.
