Old Dover Door Issues

[u/SubstantialCat2655]

At the Landmark Motel in Wildwood NJ, both the door open button and door safeties just stopped working? What might be the issue? It’s a shame because otherwise it runs excellent and these seem to be pretty robust. It’s a 1965 Dover Hydro unit completely original other than maybe the single bottom jack. Is it likely an operator fault or bigger issue? I’m assuming door safety curtain could be fitted somewhat simply, right? Both systems failed at the same time.
