2020 CC Onward HP Controller Box

Received remanufacture controller. Installed, cart is working but now I have a soft buzzing sound coming from controller compartment. So I’ve turned off and set in tow mode until I contact flight systems. Anyone ever had a controller or other components make buzzing sound?

did you find out anything on the buzzing ?
 
No. Everything is working. Sound is more noticeable inside my garage then it is outside. Also, when she is down, it’s not as much noticeable. At this point, I’m just driving it.
