There are 3 different version of that relay board.
On my pinbot ( and any pics I have seen) the AC select relay is the C-11232-1 relay board, not the C-11232 relay snubber board you are using.
Quoted from bobukcat from the F14 snubber thread
Most likely cause of an electrolytic capacitor getting hot and leaking is reverse voltage across it. Are you sure the wires haven't been switched and that the cap is installed in the properly polarity?
Which is what is probably happening to the capacitor on the snubber board.
