Common faults and repair methods for SMT ion blowers
Dec 31, 2025
Ionizing air blowers may encounter some common malfunctions during use.  Below are some common problems and their repair methods:
 
1 Ionizing air blower sparks:
 
Cause of failure: This may be due to oxidation of the electrode plates from long-term use, dust or other impurities on the electrode plate surface, or unstable power supply voltage.
 
Repair method: First, check if there is dust or other impurities on the electrode plate surface, and wipe it clean with a tissue or cotton cloth. If the electrode plate is severely oxidized, the electrode plate needs to be replaced. Also, check if the power supply voltage is stable; if there is a problem, adjust it.
 
2 Ionizing air blower not working:
 
Cause of failure: This may be due to poor contact of the power plug or switch, short circuit or open circuit in the power line, or damaged components.
 
Repair method: Check if the power plug and switch are properly connected, and check if the power line is short-circuited or open-circuited. If there is a problem, eliminate the short circuit or open circuit before plugging in the power and testing the unit. If the problem persists, it may be necessary to replace components or the motor.
 
3 Ionizing air blower making noise:
 
Cause of failure: This may be due to damaged motor bearings or a problem with the motor itself.
 
Repair method: Check if the motor bearings are damaged; if so, replace the bearings or the motor.
 
4 Ionizing air blower light abnormal:
 
Cause of failure: Abnormal or no light may be due to a faulty light tube.
 
Repair method: Replace the light tube.
 
5. Fan unable to rotate:
 
Cause of failure: This may be due to power failure, circuit failure, motor failure, or the fan blades being stuck, or worn fan bearings.
 
Repair method: Check if the power supply is normal, clean the fan blades and bearings, replace the motor, etc.
 
6.Ionizing air blower balance test fails:
 
Circuit debugging: Check if the circuit is working properly, test the circuit with a multimeter, identify the abnormal parts and debug them one by one.
 
Replace components: If there are aging or damaged components in the circuit, such as high-voltage output capacitors, high-voltage output transformers, etc., they need to be replaced.
 
Adjust the distance between the ion output electrodes: If the distance between the ion output electrodes is not appropriate, it needs to be adjusted; usually the distance should be between 5-8mm.
 
7. Ionizing air blower ESD measurement does not meet the standard:
 
Equipment failure: Long-term use may lead to equipment failure, such as damage to the high-voltage power supply, electrode aging, etc., thus affecting the electrostatic elimination effect. At this point, a detailed inspection and repair of the ionizer is necessary, including replacing damaged parts to ensure the equipment is in normal working condition.
 
Improper process parameters: If the ionizer is improperly positioned or operated with incorrect parameters during use, it may lead to poor electrostatic discharge performance. The ionizer's operating procedures should be checked to ensure it is operated with the correct parameters and in the correct position.
 
Gas pollution: High concentrations of gas pollutants in the environment can affect the ionizer's electrostatic discharge performance. Therefore, the ionizer should be used in a clean, pollution-free environment to avoid the impact of gas pollution on equipment performance.
 
Circuit problems: Circuit problems in the ionizer can also lead to substandard measurements. The circuit should be checked for proper operation, and a multimeter should be used to test the circuit, identify abnormal parts, and troubleshoot them one by one.
 
Component aging or damage: Components in the circuit, such as high-voltage output capacitors and high-voltage output transformers, can affect the ionizer's performance if they are aged or damaged. Aged components should be regularly inspected and replaced to ensure stable operation of the equipment.
 
Inappropriate distance between ion output electrodes:  If the distance between the ion output electrodes is too close or too far, it can lead to problems with achieving the required balance. The distance between the ion output electrodes should be checked and adjusted to maintain it within the appropriate range (usually 5-8mm).
 
When performing the above inspections and repairs, ensure that the equipment is powered off to avoid the risk of electric shock. If you are unsure how to perform the repairs, it is recommended to contact professional maintenance personnel or the manufacturer for inspection and repair. Furthermore, regular cleaning and maintenance of the ionizer can effectively reduce the occurrence of malfunctions and improve the stability of the equipment's performance.
