The left-right symmetric models (LRSM) generally include type-I and type-IIinduced seesaw mass as a hybrid mass for the light-active neutrinos. Assuming aparticular form of Dirac-type coupling, the Majorana-type coupling present inthe seesaw mass formula can be expressed in terms of low-energy neutrinooscillation observables and vacuum expectation values (vevs) of the scalarfields present in the model. The Majorana-type coupling thus admits eightdifferent solutions by considering the interplay of type-I and type-II termsdominate the light neutrino mass. We study the role of all eight solutions inthe lepton number violating neutrinoless double beta decay ($0\nu\beta\beta$)process. In LRSM, the right-handed neutrinos, triplet scalars, and gauge bosonsof the left and right sectors act as mediators of new contributions to the$0\nu\beta\beta$ process. As a result, the effective mass of electron neutrinoappearing in the decay width would be a function of $v_R$ (vev of the Higgstriplet of the right sector) along with other parameters of the model, throughthe masses of the new contributions. The energy scale, $v_R$ can be consideredas the new physics scale which allows exploring physics beyond the StandardModel. Considering the present and future sensitivity of searches of$0\nu\beta\beta$, we study the role of eight different solutions of theMajorana coupling matrix. In our study, the inverted hierarchy of lightneutrino masses is disfavored for all solutions keeping future sensitivity ofeffective mass in the picture, if the lightest mass of active neutrinos isbelow $0.001$ eV. Also, our study shows a possibility of new physicscontributions saturating the experimental bound on effective mass for $v_R$ inthe range of $10$ TeV for two particular solutions of the Majorana couplingmatrix.
