|In response to Re: Hot water heater upper thermostat reset|
: : I have a 40 gallon Rheem electric hot water heater. Abruptly last week, my wife declared that there "was no hot water". So, up into the attic to have a look, the upper thermostat reset button was tripped, reset it and voila, hot water. Except that now, 3 days later, it has done it again.
: : I have current running through the upper thermostat and heating element. I don't have any current running across the upper thermostat terminals that run to the lower thermostat (and, obviously, no current at the lower thermostat or heating element). However, I am unsure if I should always be able to measure current at the upper thermostat, or only when the lower element is actually supposed to be heating.
: : After that long and sad tale, my question is: How do I know which part is bad - the upper thermostat, the lower thermostat, or the lower heating element? In reading some of the other posts here dealing with electric HWH issues, I have seen references to "continuity testing", but I have no idea what this means. My preference would be to have someone professional come and look at the unit, but I live in rural Louisiana, and getting someone to come out is not so easy.
: : Any advice appreciated. Any solutions GREATLY appreciated.

Neal: After rereading my little story I feel I should add that: having current flowing from point to point is not the definition of continuity- it is the ability to carry current that matters in this context. If you have a single piece of wire and it is unbroken then both ends would have continuity with each other. Whether there is current or not. I hope someone can help you with your actual water heater problem.--bigbrother
