Is this a v2? if so the earlier version had sf1,sf2 relays off board location and they are prone to issues have you tried tightening the terminals for these relays? I have a similar issue before was loose wire at base of those relays. also are you getting any faults when its trying to run? or stored faults. Also there is a input/output menu check to make sure its matching up. I have had to remap input/outputs on board if available terminals allow, they do go bad and the led on the board on/off state can be wrong been through that headache lol. Hope this helps.
