Cause analysis and solution.
First, check whether the fan of the Huawei wireless charger CP62 is properly connected. If the connection is not good or loose, the fan will not work. Check whether there is any foreign matter or dust on the connector. Clean the connector and try to reconnect it.
Secondly, you need to confirm whether the Huawei wireless charger CP62 is in normal working condition. If the charger is overheated, overloaded, or the battery is low, the fan may automatically shut down to protect the device. At this time, you need to wait for the device to cool down or replace another charger to charge.
If the above two cases are ruled out, you can consider whether the fan of the Huawei wireless charger CP62 is damaged. You can try manually rotating the fan, and if it doesn't feel smooth or frictions, you may need to replace the fan or repair it.
Finally, you are advised to contact Huawei customer service or professional maintenance personnel. Avoid unnecessary damage or risk caused by personal operation.
