If there is no obvious fuse then the only thing would be to replace the control board but you need to check everything & try to work out why the board died. If you replace it and the fault is still there you will kill the new board and there will be no warranty on it if you are not a qualified service tech. Best to get someone out to diagnose & replace the board, then it will be on them to make sure everything is ok.
