My one exo-terra uth seems screwed up. I have it on a jumpstart and it's immediately hitting 97 and turning off. The jumpstart functions perfectly well with my emergency dome lamps. Should i buy a new uth or switch over to heat tape?

I have an oak wooden vivarium with an under tank heater cut out and terracotta tile over top the cut out.
