If you are not familiar with the element, I would get someone that is familiar with one and have them do it. It's not something I would recommend you do based on your question. There's electrical, pressurized water tank, and a whole lot of water that may cause you to have a worse bad day.

yes, sounds like the temp control is bad, you should be able to google model# and thermostat to find replacement. should be fairly easy to swap out

SOURCE: Our electric water heater doesn't work.

make sure it is wired correctly, check circuit breaker, check breaker built on to element. If all fails, and it is determined your not getting power to it, you may need a electrician. Be careful. good luck.
