Fan Failure Diagnosis and Recovery Guide

When your mining machine encounters fan failure, it may cease to function properly, which could result in no hashrate being generated and specific indicator lights signaling the malfunction. You can follow the steps below to diagnose the faulty fan and take appropriate corrective measures.

 

1. Fan Failure Diagnosis for KS3 and KS5 Series

Symptoms of Failure:

Indicator Light Status:

When a fan failure occurs in KS3 and KS5 series mining machines, the machine will not generate hashrate upon startup, and the D1 and D3 indicator lights will blink.

Diagnosis Steps:

Physical Inspection:

Power off the machine and disconnect the cables. Visually inspect the fan for any physical damage or deformation of the fan blades. Ensure there are no foreign objects (such as dust, cables, or small items) obstructing the blades or inside the fan, preventing it from functioning properly.

Check via WEB Interface:

Power on the machine and log in to the WEB interface. Navigate to the fan speed information page and check the RPM of all fans. If a fan shows an RPM of 0, that is the faulty fan.

 

Recovery Steps:

Replace the Faulty Fan:

If a fan is physically damaged or still shows 0 RPM after manual adjustments, it needs to be replaced. If you can replace the fan yourself, refer to the fan specifications and purchase a fan of the same model. While replacing the fan, you can quickly locate the faulty one by referencing the silkscreen labels on the control board. The labels J11, J12, J13, and J14 correspond to Fan1, Fan2, Fan3, and Fan4 as displayed on the WEB interface. For fan specifications and official purchase links, click below:

2. Fan Failure Diagnosis for KS0, AL0, and RX0 Series Home Mining Machines

Symptoms of Failure:

Indicator Light Status:

For KS0, AL0, and RX0 series machines, a fan failure will result in no hashrate generation upon startup. The green light will turn off, and the red light will continuously blink.

Diagnosis Steps:

Physical Inspection:Power off the machine and disconnect the cables. Check the fan blades for any physical damage or deformation. Ensure no foreign objects (such as dust, cables, or small items) are blocking the blades or inside the fan, preventing it from functioning properly.

Check via WEB Interface:

Power on the machine and log in to the WEB interface. Manually set the fan speed. If a fan still shows an RPM of 0 after setting, that is the faulty fan.

Recovery Steps:

1. Reset the Machine:

First, reset the machine to rule out any firmware issues that may be causing the fan malfunction.

2. Replace the Faulty Fan:If a fan is physically damaged or still shows 0 RPM after manual adjustment, it needs to be replaced. If you can replace the fan yourself, refer to the fan specifications and purchase the appropriate model through the link below:

3. Impact of Fan Failure on Machine Operation

When a mining machine detects a fan malfunction during startup self-diagnostics, it will halt the hashrate to prevent damage to the hashrate board. It is crucial to repair or replace the faulty fan promptly to restore the machine’s normal operation.

By following these steps, you can quickly diagnose and resolve fan failures, ensuring that your mining machine continues to operate efficiently. If you have further questions, feel free to contact our customer support team.
