In that case, yes it is not only possible, but quite simple and inexpensive. A new thermostat should run you about $20.00.Rudd 40 gall Domestic Water Heater is it possible to replace the thermostat without having to change heater?It is possible to do but as mentioned earlier, the cost may be close to the price of a new heater, and that is if you can find someone to sell one to you. Most gas companies or parts houses will not sell to you with out a gas license of some sort.
If you do mange to get one, drain the water heater. Remove the pilot tube, main burner tube, and thermocouple. With a large pair of adjustable pliers or a large pipe wrench, unscrew the thermostat. Have the other thermostat already prepared with pipe lubricant and replace it.
