How to Locate the Problem of Asic Miner and How to Solve It

October 31, 2025 On May 12, 2025

Are you still worried about ASIC miner hardware problems? Let’s learn how to diagnose, troubleshoot and fix common ASIC miner failures to make your mining smoother.

Some of our customers may sometimes worry about crypto miners not working properly because buy ASIC miners are very expensive. If there is a problem, the crypto miner will not be able to operate for a period of time. In this guide, Yesmining will help you identify ASIC miner failures, provide troubleshooting steps, and feasible repair solutions to get your ASIC miners back to normal operation.

The Most Common ASIC Miner Failure Symptoms

Before repairs, please recognize the following may be red flags:

Sudden drop in hashrate: The mining hashrate drops significantly (for example, the hashrate of 105T is only 90T or less).

Overheating: The fan is running too noisy or the miner is shut down directly.

Connection failure: The miner cannot be detected by the mining pool or management software, and the machine cannot display the hashrate value.

Prompt error code: Hardware-specific alerts (for example, “Hardware Error” on Antminer and the error code prompted in the log).

Unusual noises: The fan or chip makes a grinding or humming sound.

Step 1: Diagnose the Problem

A. Check the hardware connections.
Power: Make sure the power cable and power supply are firmly connected, and only one of the two ports is connected.

Ethernet/Network: Check the LAN cable and router settings. If there are other cables, replace the other cables for testing, and you can also try different router ports.

Cooling system: If the fan has too much dust, clean the fan and make sure it rotates normally (without deformation).

B. Check the software and firmware.
Check whether the mining pool is set up correctly and whether VPN operation is required on the router.

Firmware update: Outdated firmware may cause instability. You can visit the official website of the ASIC brand to get updates.

C. Monitor temperature.
Use the built-in tool to get the chip temperature. The ideal operating temperature of most ASICs is between 60°C and 80°C.

Step 2: Troubleshoot Specific Problems

Issue 1: Low hashrate.
Possible causes: overheating, ASIC chip failure, or software configuration error.

Solution:

Clean the dust from the heat sink and fan.

If the temperature soars, please replace the thermal grease on the chip (strong DIY ability).

Check the background to see if any chips are offline (a chip will be shown in red in the background).

Reboot and reconfigure the mining software settings.

Issue 2: Miner not detected.
Possible causes: network problems, IP conflicts, or control board failure.

Solution:

Assign a static IP to the miner. (Set up through a router)

Test with another router or Ethernet port.

Reset the miner control board (see user manual).

Issue 3: Frequent hardware errors.
Possible causes: hashboard failure, insufficient power, or voltage fluctuations.

Solution:

Test by isolating a single hashboard.

Use a voltage regulator or PDU to ensure stable power input, or replace it with a new PSU.

Step 3: Advanced Repair

A. Replace the faulty component.
Fan: Order a compatible replacement and follow the disassembly guide.

Hashboard: If a specific chip fails, consider seeking professional repair service (self-repair may cause further damage).

B. Re-flash firmware.
Regular cleaning: Dust accumulation is the most common cause of overheating. Please clean the miner regularly (every month).

Surge protection: Buy an official power supply to prevent power failure.

We also offer high quality accessories which can be purchased in our store.

When To Seek Professional Help

If troubleshooting fails, contact the Yesmining support team or a certified repair service. Modifying sensitive components yourself may void the warranty, so proceed with caution.

In Summary

Quickly diagnosing and fixing ASIC miner errors ensures maximum mining efficiency and ROI. By following these steps, you can minimize downtime and extend the life of your hardware. If you encounter any problems when installing or running Asicminer, you can contact the Yesmining team to answer your questions!If your miner keeps having problems or doesn’t work well even after repairs, and downtime is costing you more than fixes, we recommend upgrading to newer ASIC miners that perform better and save power consumption.
