  The existence of light sterile neutrinos, as predicted in several models, can
help to explain a number of observations starting from dark mater to recent
anomalies in short baseline experiments. In this paper we consider two models -
Left-Right Symmetric Zee model and Extended Seesaw model, that can naturally
accommodate the presence of light sterile neutrinos in the eV to MeV mass
scale. We perform a detailed study on the neutrinoless double beta decay
process which receives major contributions from diagrams involving these light
sterile neutrinos. Considering a number of theoretical and experimental
constraints, including light neutrino masses and mixings, unitarity of the
mixing matrix etc., we compare our predicted values of the half-life of
neutrinoless double beta decay with the experimental limits. This can put
significant constraints on the neutrino mass, active-sterile neutrino mixing
and several other important parameters in these models.
