Abstract:	We present the analysis of EZ Lyn variability on the time scale of minutes-days, using photometric data obtaining with 2.6-m telescope of CrAO in 2012–2016 years. For 2012–2016 years we detected a previously unknown long-term periodicity of 0.52 d. The orbital brightness modulation could display some cycle-to cycle profile variations. We found that known non-radial white dwarf pulsation at 310 c/d is no longer dominant one, instead, a pulsation at 300 c/d became the most significant one.
