Is changing the thermostat on a water heater easy enough for a novice?

Of course, I have never done this type of task before but I need to know if I am looking towards trouble if I consider this task on my own? Help|||knowledge is key, 2 t-stats, upper and lower on most WH%26#039;s. look on back of t-stat package and read wireing diagram. The only problem that I%26#039;ve encountered is that some wires may be too short when you change to new t-stat. You can get some 12 gauge wire from hardware store and possible need some yellow wire nuts to compensate for wire shortness if you run into that problem.Set both t-stats at same temperature. A $12 volt ohm meter will be good to have to make sure you don%26#039;t get shocked ( always check for no power before touching wires or t-stat) it%26#039;s also good for testing elements for continuity (seeing if they are good or fried)|||First and foremost, make sure you turn the electric off for the heater. Double check with a meter or probe that the electric is shut for the heater. Follow the manufacturers directions and you won%26#039;t have a problem changing the t-stat. Are you sure the t-stat is not functioning??|||Label wires, keep track of where the screws came from, keep the old part until you have the new part installed and tested and you should be okay. You may also want to take photos as you go along as a mental jog should problems arise.





GL.|||The thermostat usually the last thing to go on a h2o htr. What is your problem. Is it gas or electric. Provide more info.|||Hmmm. Do you mean change the setting or do you mean change out the thermostat for a new one? See the other answers to just change the setting.





Removing and replacing the thermostat is not a job for a novice. Find someone who has done it and have them help you.|||It depends on the brand or style of thermostat , most of what I deal with use a clip to hold it against the tank , just lift enough to release the Th and slide it up (some can be tricky) of course you need the breakers off and disconnect the wires (keep track of where they go)


some have little nuts or screws to hold the Th up to the tank another has a probe that screws into the tank





I would guess your heating elements are the problem|||Changing the stat is fairly easy. Make sure you turn the power off first. Other than that you might want to make sure your changing the right part before you go to the trouble.. God Bless.|||Changing the thermostat is a VERY simple job, just 2 bolts and 2 wires. Look at it and make notes as to where the wires go. Good luck with your project.|||If you are just changing the Thermostat, then you have to switch off the electric supply to the thermostat first which is ususally a switch by the Immersion hater. Then remove the plastic cover, and unscrew the wirs to the thermostst. Withdraw the old thermostst and fit the new one and re connect the wires as they were fitted. Replace the cover, and switch the electric back on. Job Done!!


There is no need to drain the tank if it is only the thermostat to be changed.|||I guess the question is why do you think you need to adjust the thermostat?


If your water has been consistently hot and suddenly it%26#039;s not, you have other issues (bad element(s), etc).





Below is a link showing, step by step, how to do it...|||It should just be a dial somewhere near the bottom. It%26#039;s just a dial and it says hot one way and cold the other. Turn it whichever way you want.
