AMS Blinking Red Light time to time during print operation

Hi Everybody,

My AMS (X1C ordinary AMS) is sometimes starting blinking red light during print operation. No complain about print operation or quality. Everything seems normal. I already check the AMS connection cable and plugs.
The Problem is not happen all the time comes rarelly.
Strangest thing even if there is a blinking red light on every slots of AMS , feeding is continue and no message on printer screen. Like a ghost :))
I am thinking of the change in order ,
First AMS Interfce Board on AMS and check
Second AMS Connection Cable and check
Third AMS interface board on machine
I don’t want think about AMS main board because it’s expensive.
Could you please give me any advice.
Thank you.

You may lock up Bambu labs AMS blink codes. That might help you diagnose the issue.
