How to troubleshoot matrix over current fault xx31 and xx32 GT Series inverter?

Inverter faulted on left or right matrix over current.

Product Line:
GT commercial series inverters 


The driver board is what drives the IGBT to produce power.

Swapped the driver board and see if the fault followed. Take the left driver board and install it to the right side and take the right driver board and install to the left side.
 If the fault does not follow the board then call 866-519-1470 option 3 & 3 to open a case.
