recently, the C39 capacitor on my VESC blew up. I took a short ride on my board, had to cross the street and picked up the board. On the other side, the board did not accelerate. So i connected the VESC to BLDC tool and it did not show any fault code. It even says there is current in motor when triggering the throttle on the remote but the motor will not spin. When i power the VESC it does not blink three times on start up. Later i recognized that C39 blew up. I contacted the supplyer (Enertion) but the do not respond since 4 days or so.
So my question: What is the C39 for and can i repair the VESC on my own or should i try to send it back to Enertion if they eventually will respond? Also, do I have any warranty on the VESC? I purchased it roughly 1 month ago and wrote the board for an overall of maybe 5-6 hours. Moreover, the capacitor must been blown up when there was nearly no load on the board/VESC what seems to me like it was not my fault and even something like a production failure.
