Mitsubishi Service & Repair Forum
I have a Mitsubishi lathe model M-TC8A serial TC8A-005. I believe one of the soft keys on the controll is sticking. I have removed both the small board and large board and cannot find anything wrong with them. I am pretty sure that one is sticking because I can here the beep and all my lights flash on and off on the controll. Is there a way to test these boards? Operator Board unit MH402A-1 serial 8911007. I am not sure whick numbers on the boards are part numbers.Thanks,Tim Van Bruggen, ownerCAM Specialties, LLC

Hi there, I understand you're having an issue with the Mitsubishi FR-S540E-0.75K-EC unit. From what I gather, it's a 0.75kW three-phase micro inverter compatible with the FR-DU04. The problem seems to be that it's not working as expected. Let me know if you need further assistance.—> …Purchase or Repair:
