However, like any high-performance hardware, occasional faults may occur. This comprehensive troubleshooting guide helps you identify and fix common ICERIVER error codes and hardware issues efficiently.
1. Power Supply Issues
Error: Power Indicator Light Not Working
Cause: Loose connection, faulty adapter, or unstable input voltage. Solution:
- Check and firmly reconnect the power cable to the miner.
- Replace the power cord or adapter if damaged.
- Ensure voltage is within AC 170V–300V range.
- If unresolved, contact ICERIVER support for power module replacement.
Error Codes: 233–239 (Overtemperature Protection)
Cause: High ambient temperature or dust accumulation. Solution:
- Keep the environment below 35°C (Normal Mode) or 30°C (Performance Mode).
- Clean dust from power supply vents for proper airflow.
- Tighten copper bar screws to ensure firm electrical contact.
2. Fan-Related Faults
Error Codes: 110/111/120/121 (Fan Speed Abnormal)
Cause: Fan cable is loose or fan motor is damaged. Solution:
- Reconnect fan cables securely.
- Replace defective fans (use original ICERIVER parts).
- If the control board driver fails, update firmware or replace the control board.
Error Code: 140 (Fan Overspeed)
Cause: High temperature environment or fan aging. Solution:
- Improve ventilation or install external cooling fans (≤5V/0.5A).
- Replace with a high-speed fan designed for hot conditions.
3. Network Connection Problems
Symptom: Network Port LED Off
Cause: Unstable network or damaged port. Solution:
- Reconnect or replace Ethernet cable and test with another port.
- Check router/switch status and replace if faulty.
- Verify correct IP configuration (DHCP or Static IP).
Symptom: “404 Not Found” When Accessing Miner IP
Cause: Web interface not fully initialized. Solution:
- Wait 1–2 minutes after powering on before accessing.
- Restart miner and refresh browser.
- If persistent, re-flash or upgrade firmware.
4. Temperature Sensor and Overheating Issues
Error Codes: 300–302 (Temperature Sensor Failure)
Cause: Loose hashboard cable or faulty sensor. Solution:
- Reseat the connection cable between hashboard and controller.
- Replace the defective sensor or hashboard.
Error Codes: 350–352 (Overheat Protection Triggered)
Cause: Poor ventilation or blocked airflow. Solution:
- Remove any covering or obstruction around miner vents.
- Use external cooling fans or lower ambient temperature.
- Check fan RPM; replace if malfunctioning.
5. Hashrate Issues
Symptom: Hashrate Drops or Shows Zero
Cause: Unstable network, defective chip, or faulty hashboard. Solution:
- Check internet connection and replace network cable if needed.
- Observe average hashrate over 12 hours; short-term fluctuations are normal.
- If consistently low, replace faulty hashboard or chips.
Symptom: Pool Hashrate Differs from Local Hashrate
Cause: Network latency or pool statistics variance. Solution:
- Ensure network stability and reduce latency.
- Refer to the pool’s 24-hour average hashrate instead of real-time data.
- Double-check pool address and configuration accuracy.
6. Firmware & Control Board Errors
Error Codes: 800–802 (Firmware Update Failed)
Cause: Incomplete or corrupted firmware file. Solution:
- Download the latest firmware from ICERIVER’s official website.
- Ensure a stable power source during upgrade.
- Contact technical support if upgrade repeatedly fails.
Error Codes: 710/712 (Control Board Unstable)
Cause: Firmware incompatibility or board hardware fault. Solution:
- Update to the latest official firmware version.
- Tighten control board screws to ensure stable contact.
- Replace control board if instability persists.
7. General Troubleshooting Checklist
- Check Indicator Lights: Power, network, and fan LEDs can quickly show the miner’s status.
- Verify All Connections: Power cable, hashboard, and Ethernet must be tightly connected.
- Restart the Device: Many temporary faults are resolved by a simple reboot.
- Keep Firmware Updated: Always use the latest firmware for bug fixes and improved stability.
- Contact Support: If self-troubleshooting fails, reach out to ICERIVER Technical Service for professional assistance.
