Troubleshooting
Symptom-based troubleshooting guides for diagnosing and resolving ASIC miner faults.
Overview
Start here when a miner is not operating correctly. Each guide targets a specific symptom, walks through the most likely causes in order of probability, and provides step-by-step diagnostic procedures. Guides apply across brands unless otherwise noted.
By Symptom
- No Hashrate — Miner is powered on but producing zero hashrate
- Low Hashrate — Hashrate is below expected levels
- Abnormal Chip Voltage — Voltage domain readings outside normal range
- Board Not Detected — Hashboard not recognized by the control board
- Missing Chips — Partial chip detection on a hashboard
- High Temperature — Overheating and thermal shutdown events
- Fan Errors — Fan speed warnings, fan not detected, or abnormal RPM
- Power Issues — PSU faults, voltage errors, and power delivery problems
- Miner Keeps Restarting — Watchdog resets, boot loops, and frequent reboots
- Network Problems — Pool connection failures, IP conflicts, and DNS issues
- Firmware Corruption — Checksum errors, NAND failures, and recovery procedures
