Reason analysis:
Power supply problem: the power cord is not connected, the plug is loose or the power switch is not turned on, which will cause the machine to be unable to power on; Power supply failures such as low voltage, power failure, etc., will also cause the machine to not work.
Pressure switch failure: The pressure switch is set improperly or malfunctioned. When the pressure of the gas reservoir reaches the set value, the pressure switch may prevent the machine from starting; Or the pressure switch is damaged and cannot normally control the start and stop of the machine.
Overload protector action: When the air compressor is overloaded or the internal components fail, the overload protector will automatically trip, so that the machine stops running.
Motor failure: motor winding short circuit, break, burn or bearing damage and other problems, will cause the motor can not rotate normally.
Elimination method:
Check the power supply: Ensure that the power cable is securely connected, the plug is firmly inserted, and the power switch is on. Check whether the power supply voltage is normal. If it is abnormal, contact a professional electrician for maintenance.
Check the pressure switch: Check whether the pressure switch is set correctly and adjust it according to the device instructions. If the pressure switch is damaged, replace it with a new one.
Reset overload protector: If the overload protector trips, reset it first. Check whether the machine has overload conditions, such as excessive load, stuck head, etc., troubleshoot the fault and then restart the machine. If the overload protector trips frequently, there may be a serious fault inside the machine, and professional maintenance personnel need to be contacted for overhaul.
Maintenance of the motor: Use a multimeter and other tools to detect the resistance, insulation and other parameters of the motor to determine whether the motor is damaged. If the motor fails, the motor needs to be replaced or repaired.
