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.
