The analysis of the white dwarf pulsations of the dwarf nova EZ Lyn (which outbursted in 2010) in 2015–2020 years basedon photometry at 2.6-m Shajn telescope of the Crimean Astrophysical Observatory is presented. It revealed an increasein the period of pulsations from 234 to 756 sec. In accordance with the empirical relationship between the period of thepulsations and the temperature of the white dwarf, this means a fast cooling of the white dwarf after the 2010 outburst.
