That's weird. I have done a bunch of work on this awning in the past. I would call Fleetwood first. Then I would call the makers of the Illumaplex panel (I think Precision Circuits).
The reason being is the blinking panel light. I've not seen this. My guess is they would know why this might occur.
Also, did you check the power connection in the BCC box? That is where the power ultimately comes from for the awning.
I don't make it much on here anymore so will not see your reply to my comment. Drop me a direct message and when I come back on I will see it.
