So i woke up today and my heater was stuck on. Usually my tank is around 76-77 and it was 82. I unplugged the heater and left it like that for a few hours. I pugged it back in and it seems to be working fine and the temp. has slowly gone back to the normal. I really dont have the money to spare for another heater for a few days so do you think it just kinda glitched or that i shouldnt trust it and get a new one asap.
