How to fix “Chain only find 0 ASIC” on Bitmain Antminer S17+ ASICs

Start with safety and logs

Power down before opening a miner, label cables before moving boards, and capture logs before repeated reboots erase useful evidence. Record model, firmware, pool, uptime, fan speed, temperature, reject rate, chain count, and the exact error text.

Confirm the fault class

Separate configuration faults from hardware faults first. Pool errors, DNS failures, bad worker names, overheating, weak power, fan faults, and missing hashboards can look similar from the dashboard but require different fixes.

Document the test path

Change one variable at a time and keep the before/after result. Note cable swaps, PSU swaps, firmware changes, pool changes, fan replacements, ambient temperature, and whether the fault follows a hashboard, control board, network, or power source.

When to escalate

Escalate to professional repair when there is a burned smell, melted connector, breaker trip, corrosion, repeated hashboard loss, liquid exposure, or a board-level fault that returns after a basic cable, power, firmware, and airflow check.

After the fix

Run the miner long enough to confirm stable accepted hashrate, fan behavior, chip temperature, reject rate, and pool-side reporting. A dashboard that looks normal for five minutes is not enough evidence for a recurring power, heat, or hashboard fault.

If you’re an ASIC miner and are experiencing the issue of “Chain only find 0 ASIC” on your Bitmain Antminer S17+ ASICs, it can be frustrating and concerning. This error message indicates that the hash board is unable to detect any of the ASICs on the chain, which can lead to decreased mining efficiency or even total failure of the mining operation. However, there are a few steps that you can take to troubleshoot and fix this issue. This guide will provide you with a step-by-step approach to identify the root cause of the problem and implement the necessary solutions to get your Bitmain Antminer S17+ ASICs back up and running efficiently. It’s important to note that these steps should only be attempted by someone with experience in ASIC mining and electronics, and caution should be taken to avoid any potential risks involved in handling and modifying the hardware.

Troubleshooting Steps to fix “temperature sensor fault” on Bitmain Antminer S17e

Check the kernel log: The first step is to check the kernel log of your Bitmain Antminer S17+. Look for “check_asic_number_with_power_on: Chain[0]: find 0 asic, times 0” or “check_asic_number: Chain 0 only find 0 asic, will power off hash board 0” messages. This will help you identify which chain has the issue.

Swap data cables: Once you’ve identified the problematic chain, swap the data cable of the hash board that’s showing the “Chain only find 0 ASIC” message with the data cables of two other normal hash boards. This step helps to determine if the issue is with the cable or the hash board itself.

Check voltage domain: If swapping the data cables doesn’t fix the issue, use a fluke17B+ multimeter to check whether the total voltage domain of the hash board is normal. If it’s abnormal, you need to check whether the voltage of each PIC, MOS tube, and boost circuit is abnormal.

Check RI signal voltage: If the voltage domain is normal, check the RI signal voltage. First, find the RI signal of a group of chips on the edge of the domain for detection in the middle domain. If it’s normal, check it forward. If it’s abnormal, check it backward. The RI signal is transmitted from the last chip to the first chip.

Check for chip pseudo-soldering: If the kernel log and test fixture detection show “ASIC=0 or NO hash board”, check whether the chip’s RI signal voltage and the ground value are abnormal. If there’s any abnormality, it’s likely caused by chip pseudo-soldering. Soldering twice first. If it cannot be solved, replace the faulty chip.
