  In TeV scale left-right symmetric models, new dominant predictions to
neutrinoless double beta decay and light neutrino masses are in mutual
contradiction because of large contribution to the latter through popular
seesaw mechanisms. We show that in a class of left-right models with high-scale
parity restoration, these results coexist without any contravention with
neutrino oscillation data and the relevant formula for light neutrino masses is
obtained via gauged inverse seesaw mechanism. The most dominant contribution to
the double beta decay is shown to be via $W^-_L- W^-_R$ mediation involving
both light and heavy neutrino exchanges, and the model predictions are found to
discriminate whether the Dirac neutrino mass is of quark-lepton symmetric
origin or without it. We also discuss associated lepton flavor violating
decays.
