  We study the second-order phase transition (SOPT) for the spherically
symmetric Kehagias-Sfetsos (KS) black hole in the deformed H\v{o}rava-Lifshitz
gravity by applying the methods of equilibrium and non-equilibrium
fluctuations. We find that, although the KS black hole has only one mass
parameter as the usual Schwarzschild ones, the SOPT will take place if the mass
of the KS black hole changes across the critical point
$\frac{\sqrt{5+\sqrt{33}}(\sqrt{33}-1)} {16\sqrt{\omega}} $. The result show us
that there is difference between the H\v{o}rava-Lifshitz gravity and the
Einstein's gravity theory.
