Test the lower portion of the thermostat, by touching one lead to the common terminal (next to the temperature setting) and the second lead to the left heating element terminal. If the water in the tank is below the thermostat’s set temperature, the multimeter should read close to zero ohms of resistance.
What causes a water heater thermostat to burn up?
Chances are you have a failed or failing element that is drawing too much power, but not quite enough to trip the breaker or you have a failed thermostat.
