1. Check the power cable connection: First, check whether the power cable is correctly connected to the power module and power socket. Make sure the plug is firmly in contact and check that the socket is electrically active.

2. Check the input voltage: Use a voltmeter to measure whether the input voltage is normal. If the input voltage is lower than the rated voltage range of the power module, a fault may occur.

3. Check the power switch and indicator: Check whether the switch is on and the indicator is on . If not, it may be a switch fault or other internal fault of the power module.

4. Check the output voltage: Use a voltmeter to measure whether the output voltage of the power module is normal. If the output voltage is abnormally low or zero, it maybe the output circuit faulty of power module.

5. Check the protection circuit: Some power modules have overcurrent or overheat protection. If the power modules are overloaded or overheated, they may shut down automatically. Wait for the power module to cool down and return to normal before discovering the fault.


6. Replace the power module: If the fault persists after the above steps, you may need to replace the power module. Make sure to select the new module that matches the original module and ensure that it is properly installed and connected.

Note:Please make sure of that the power supply should be switch off before any repair or overhaul to avoid electric shock and other safety risks. If you are not sure how to repair, please consult a professional for help.
