My electric hot water tank is putting out very hot water. Can I find out which thermostat is bad without an amp meter? The top one clicks off at a high temp, and the lower at a lower temp.

  • A volt meter would do, or if you had a spare socket and a bit of wire, you could use a lightbulb. – Tyson May 21 '16 at 1:05
  • Turn off every other large power consumer in your house, and then watch the main electric meter while you adjust the thermostats. – Daniel Griscom May 21 '16 at 11:04

So, did you try turning the thermostats down? And did the WH continue to heat? Usually the coils make some noise as they heat the water. Like a pot on stove.

Try dialing them up and down. If there is one that never shuts off then that one is broke.

Good luck!
