ASIC Troubleshooting Guide
This guide helps you diagnose and fix common issues with Bitcoin ASIC miners using simple, structured steps.
General Rule: Change One Thing at a Time
When troubleshooting, avoid changing multiple things at once. Adjust one variable, observe the result, then continue.
Problem: Miner Is Not Powering On
Possible Causes
- No power at outlet or breaker tripped
- Faulty power cord or loose connection
- PSU failure
Steps to Check
- Verify the breaker is on and not tripped.
- Test the outlet with another device (lamp or tool).
- Inspect power cords and connections for damage or looseness.
- If you have a spare PSU, test with it if you are comfortable doing so.
Problem: Hashrate Is Lower Than Expected
Possible Causes
- High ambient temperature
- Dust buildup restricting airflow
- Under-powered or failing PSU
- Thermal throttling
- Pool configuration errors
Steps to Check
- Check temperatures on the miner dashboard; compare to normal ranges for your model.
- Inspect fans for dust; clean filters and surrounding area.
- Make sure intake air is cool and hot exhaust air is not recirculating.
- Confirm PSU is correctly sized and not overheating.
- Double-check pool URL, worker name, and settings.
Problem: One or More Hashboards Offline
Possible Causes
- Loose data or power cable to the hashboard
- Overheating on a specific board
- Physical damage or failing chips
Steps to Check
- Power down the miner safely and disconnect from power.
- Visually inspect and reseat power and data cables to each hashboard.
- Check for obvious physical damage, corrosion, or burnt components.
- After restarting, monitor temperatures and see if the board returns.
- If the problem persists, you may need professional repair service.
Problem: Miner Overheating or Thermal Shutdown
Possible Causes
- Room temperature too high
- Insufficient ventilation or blocked exhaust
- Dust on heat sinks or fans
- Fan failure or reduced RPM
Steps to Check
- Verify room temperature; consider more ventilation or a different location.
- Ensure the miner exhaust has a clear path and is not blowing into a closed space.
- Inspect for dust buildup and clean carefully if needed.
- Check fan RPMs in the miner dashboard and listen for failed or noisy fans.
Problem: High Reject Rate in Pool
Possible Causes
- Network latency or packet loss
- Incorrect time settings
- Overclocking or unstable tuning
- Pool issues
Steps to Check
- Confirm your internet connection is stable; avoid Wi-Fi for miners.
- Reboot your router and switch if needed.
- Return miner settings to stock if overclocked.
- Try a different region server for the same pool or another pool temporarily.
Problem: Miner Keeps Rebooting
Possible Causes
- Power instability or undersized PSU
- Overheating leading to thermal protection
- Firmware bugs or corrupted configuration
Steps to Check
- Monitor voltage and amperage with a reliable power meter.
- Check logs on the miner dashboard for errors.
- Reduce any overclock/tuning and return to default settings.
- Consider reflashing to stable firmware if recommended by manufacturer.
Problem: Network Connection Lost
Possible Causes
- Faulty Ethernet cable or port
- Router/switch issues
- Wrong IP assignment or conflicts
Steps to Check
- Test with a known good Ethernet cable.
- Try a different port on your switch/router.
- Check your router’s device list to confirm the miner’s IP.
- Power cycle router and switch if necessary.
