Which Thermostat to change

Hi there, I am not an electrician or plumber by any means but I have a huge problem with my electric hot water heater. The water temp is like so hot that you can not touch it, but the thing isn't running at all. Changed the element (not knowing that wasn't really the problem.) Was told that the thermostat is stuck. How do I know which thermostat to change the top or bottom one??? Before I went to work today I shut the main power off to the water heater to be on the safe side, but the big question is should I replace both thermostats and the other element. The water heater is just over a year old and go figure the warranty is over by about a month... Any help would be appreciated Thanks

How to test:
Be careful; if you are not confident and experienced working with a tester and live voltage that can kill, call in a pro!!!!!!!!!!!!!!!!!

If you can't reset your tstats and get them working, I always just replace both of them. It's easy to DIY, and you don't need to get into testing them.
1. First, keep the POWER OFF.
2. Note (remember or sketch) the number and layout of the screws on the tstats and get replacements for both with the exact same number and layout (does not have to be same brand).
3. Exchange the wires one at a time from the old to the new to the exact same screw. You can't go wrong with this method. Been doing it this way for years, and I never fool with testing a bad tstat.
4. Make certain that the tank is full of water and restore power.
Always works for me!
Good Luck!
