You are correct.

Burning wood, changes the chemical make-up of the wood.

But melting ice into liquid water does not change the chemical make-up of the water.

Yes, wood is a polysaccharides in typical, of course it also consists of xylem and phylum, xylem is what people usually refer to as WOOD. Any combustion is a transfer of chemical energy into heat. And melting of ice also requires heat, it is endothermic, the reason ice goes back to water automatically is that, room temperature provides sufficient heat for it to do so.
