Axial Fan: Common Issues and Solutions for Optimal Performance

The axial fan provides reliable performance with minimal power consumption, from automotive use and camping equipment to off-grid living and industrial machinery, the axial fan has become a popular choice for various applications. However, like other equipment, axial fans may also encounter common issues over time, such as not spinning, excessive noise, and poor cooling performance. In the following text, this article will delve into the causes of these problems with the axial fan and offer practical solutions.

Axial Fan Not Spinning

Possible causes

Power not connected or insufficient voltage: the axial fan is not receiving enough voltage to start.

Broken or loose wiring: the wire connecting the axial fan may be broken or have poor contact.

Damaged motor inside: the motor may be damaged by prolonged use or manufacturing defects.

Solution

Check the power supply: Use a multimeter to measure the voltage to check if it meets the requirements of the axial fan.

Check the connections: Ensure that the positive and negative wires are connected correctly or not, and the connectors must be sturdy, not loose, and there must be no rust.

Test the motor: Connect the axial fan directly to another known good power source. If the fan still does not spin, the motor may need to be repaired or replaced.

Excessive noise from Axial fan

Possible Causes

Worn bearings need to be lubricated: prolonged operation may cause the bearings of the axial fan to wear out and need to be lubricated to reduce friction.

Fan blades are deformed or blocked by foreign objects: deformation of the blades or accumulation of dust and debris may cause the axial fan to make noise.

Installation problems or vibration amplifies noise: unstable fan installation or vibration may result in increased noise.

Solution

Lubricate the bearings: Use silicone oil or light machine oil for lubrication, avoiding using grease that is too thick, or the bearings will not be agile.

Check the blades: Clean the dirt around the axial fan and inspect whether the blades are deformed. Slight deformation can be manually corrected, but severe deformation will require replacement.

Adjust the installation: The fan must be securely installed, adding rubber pads or shims to reduce vibration.

Poor performance of Axial fan

Possible Causes

Low fan power or weak airflow: The airflow from the axial fan is not enough to cool the unit.

Incorrect fan installation: The fan is installed backwards and the airflow is in the wrong direction.

Dust build-up impedes airflow: Dust and debris build-up reduce airflow from the axial fan.

Solution

Check fan specifications: Check whether the fan's CFM and RPM are sufficient. If not, consider upgrading the fan or adding extra cooling components.

Verify mounting orientation: The fan should blow the heat source, not in the inverse direction.

Clean the dust: Clean the fan and its surroundings often, just use compressed air or a soft brush.

Even if the axial fan is of high quality, sometimes it may encounter problems, such as not spinning, unstable rotation speed, loud noise, or poor heat dissipation. These issues are mostly due to unstable power supply, fluctuating voltage, excessive dust, parts wear, or the fan too small. To ensure that the axial fan continues to work stably and efficiently, JLCMC reminds everyone to keep the environment clean, remove dust and debris in the fan and pipeline, ensure that the power supply facilities have sufficient capacity and stable voltage, avoid running out of phase, and regularly replenish or replace the bearing lubrication.
