6 Common ASIC Miner Repair Errors Repeated by 80% of Miners

Why Proper ASIC Miner Maintenance Matters

As the price of Bitcoin continues to rise, the computing power of BTC is also gradually increasing, and more and more miners are beginning to invest in thee field of BTC mining. As the production equipment of Bitcoin, how should we maintain our BTC mining machines and reduce asic miner repair in time? A staggering 80% of mining machine failures result from simple maintenance oversights. To ensure the continuous operation of the equipment and maximize profits, this article will improve the overall benefits of your mining machine from the daily inspection of the following major issues.

Check Hashrate Regularly

Check the hashrate of the mining machine every two hours. You can use the batch management software BTC Tools to check it on site or log in to the corresponding mining pool website to check the hashrate. BTC Tools can batch set up mining pool miners and check the hashrate temperature in real time.

If the hashrate is low, we need to check the possible problems in time. It may be caused by overheating of the machine, network signal problems, or machine parts failure. Early detection of these issues prevents costly mining equipment repair services.

Monitor Power & Voltage Stability

ASIC miners are extremely sensitive to voltage fluctuations. Maintaining power within the standard range is critical to minimize bitcoin miner repair needs and prevent hardware damage.

Use a multimeter to check the voltage of the mining machine PDU socket every day to see if it is within the normal range of 220V±10%. Voltage that is too high or too low will cause unstable operation or failure to work, and may even burn the power supply or mining machine.

Check the mining machine regularly for leakage. Some mining machines may be charged due to poor grounding, and it is easy to damage the control board and hashrate board when operating the mining machine.

Pro Tip: If abnormal voltage or grounding issues are detected, notify a certified electrician immediately to prevent costly miner failures.

Ensure Stable Network Connection

Regularly check whether the backup broadband line is normal. You can check it from the router background or laptop by connecting the backup network cable. The mining network and the living network need to be separated to avoid the living area accessing unknown websites involving network security.

Regularly ping the mining pool used by the current mining machine to see if the delay is stable. If the delay is as high as 100ms or more, it is necessary to check the internal and external networks. The network administrator will check whether the network equipment is faulty in the local area network. The broadband operator needs to check the equipment line for the external network. Excessive delay will cause fluctuations in computing power.

Maintaining a stable Internet connection and minimizing downtime can ensure the overall profitability of your mining machine.

Maintain Proper Temperature & Humidity

Measure the air inlet temperature of your mining machines daily,and try to keep it between 10 and 25℃. If the temperature near the air inlet of the mining machine exceeds 30℃, it is easy to cause overheating protection aleading to hashrate drops or even zero output. In such cases, you should:

• Lower the ambient temperature immediately
• Improve ventilation or activate auxiliary cooling systems
• Check for airflow obstructions caused by dust

Low temperature treatment

While most ASIC miners operate within an ambient range of 0°C to 40°C, winter conditions in northern regions can drop to -10°C to -20°C. Such low temperatures may lead to :

• Burned boards,falling boards or falling chips
• Logs showing temperature sensor errors, or high/low temperature warnings
• Cold-start failures when powering up miners suddenly

Humidity treatment

Monitor humidity near the miner’s air inlet daily. Ideal relative humidity (RH) should be kept below 65%. Excess moisture can cause:

• Condensation on shelves, PSUs, or hashboards
• Potential short circuits or permanent board damage

Key humidity management tips:

• Keep water curtains at least 2–3 meters from racks
• Adjust the flow rate to avoid raising RH levels
• Ensure proper airflow to disperse moisture buildup

Note: Long-term high humidity and poor air quality in the vicinity of large chemical plants will accelerate the corrosion of the computing board or even make it scrapped.

Perform Environmental & Dust Checks

Your mining rig is your loyal partner in crypto mining. Regularly checking the dust condition of the mining machine monthly can also reduce unnecessary miner repairs.

You can disassemble the front fan of the mining machine to check. If you find a lot of dust and catkins accumulated at the heat sink, blocking the air duct and causing high temperature protection, you need to clean it in time. Because the accumulation of dust will cause the components to overheat, leading to the risk of hardware failure. Staying on top of this simple maintenance boosts your miner’s performance and lifespan. After all, a happy miner means happy mining!

Note: Before cleaning, safely shut down the miner following the manufacturer’s instructions. Allow the miner to cool down completely before starting the cleaning process. Perform the cleaning in a clean, well-ventilated area to ensure safety and effectiveness.
