A search for various double electron capture modes of $^{ 74}$Se has been performed using an ultralow background Ge-detector in the Felsenkeller laboratory, Germany. Especially for the potentially resonant transition into the 1204.2 keV excited state of $^{ 74}$Ge a lower half-life limit of $0.70\cdot 10^{ 19}$ yr (90% credibility) has been obtained. Serious concerns are raised about the validity of obtained $^{ 74}$Se limits in some recent publications.
