If the fuse isn't blowing then the cause of the heating is definitely a poor connection in that area.
Either the fuse blades have surface oxidation / the female connectors in the fuse holder are too slack to make good contact... or possibly, the wires to the connectors are frayed and down to a few strands in which case the joint to the connector would need to be remade. It should become clear which is the cause once you start taking it apart. The current needs a good cross-section of clean metal throughout it's path. A squirt of contact cleaner when you're done will help to prevent corrosion.
