No, not all energy transfers leads to a change in phase. This is because the heat triggers the breaking of bonds (in the case of ice molecules for example) as the ice becomes liquid.
Why the heat does not lead to Phase Change
It is to be noted that the average kinetic energy dissipated by the molecules does not change when the melting is occurring.
Because of this, the molecules remain the same, hence phasing does not occur.
