MM75 - F0002

stevennoppe Posts: 65 Rating: (1)	Hello, I have a micromaster MM75 that worked well for some time now, but today when we try to run the motor we get the error : "F0002 - OverCurrent" I already checked : the motor and the wiring and everything is ok, so now my final guess is that the micromaster is broken. Or am I still missing something?

This will prove if the inverter is at fault or the motor and cables. Also if the atmosphere is dusty and damp, the inverter can fail prematurely with F0002. Remove the fan and look inside, to see if there is any corrosion and contamination.
