Air compressor inverters sometimes experience malfunctions, which may trigger an alarm mechanism due to current and voltage overload or damage to inverter components, causing the air compressor to trip. Regardless of the cause, it's important to understand how to handle inverter faults. Below is a brief analysis of inverter faults:
1. Unstable Voltage
During operation, variable frequency air compressors may experience unstable voltage. If the voltage is unstable, it can lead to overload conditions, preventing the air compressor from starting normally. Solution: Adjust the voltage regulator promptly.
2. Mainboard Damage
The mainboard of a variable frequency air compressor may be damaged during long-term use. Once the mainboard is damaged, the internal components of the equipment cannot function properly. Solution: Users should regularly inspect the mainboard and electronic components, and address any problems promptly.
3. Cooling Fan Damage
Inverters can also experience malfunctions due to overheating during operation. Solution: Regularly check if the inverter's cooling channels are blocked and if the fan is damaged. Replace or repair as needed.
4. External Input Faults
External input faults can also occur during air compressor operation. Solution: Check if the port voltage value is normal and if the short-circuit cap connecting the control board to the equipment is loose. This can be resolved by replacement or reinstallation.
