If the relay board is causing your problems, removing it will help. It's generally not needed, and it just adds another layer of unecessary complexity.

If you want to keep it, then you're going to have to listen to my suggestions. Take the circuit board out of the enclosure and inspect the board for cold solder joints, cracked solder joints and shorts. If you can't find any faults, remove the relay that's getting hot and replace it.

If you don't know how to do any of this, you really need to let a professional handle this aspect of your project.
