At this stage, we don't know for certain what's failed; the MOV might be OK, but the cap has almost certainly gone. I think a cap in that role should be either X or Y rated and that cap does not look physically big enough to be either. If possible, getting a close up and well lit pic of the fuse, MOV and 2 caps would be interesting to see.
I wonder if they started out with just the MOV (as there is no white location box for the cap on the pcb), and those were failing too often, so they added the green cap as a modification, but it does have the right rating, so the board is still vulnerable? It's all pretty unimpressive.
In the past, lots of equipment used to have a component consisting of a 100R resistor with a 0.1uF cap moulded as a single piece as interference suppressors. Many were made by RIFA and they get to a certain age (some years) and then the caps fails, sometimes quite dramatically, but 18 months...?

plus, I received a contribution of 50% of the repair from the park owners, which to be honest, I’m happy with based on the extra hassle and phone calls / emails it would take to recover the rest from M who are still refusing to play ball.
