Check for power at the switch on the instrument panel (somewhat unusual location for a water heater switch).

A friend told me to check my switch, I found that it was showing signs of overheating. It is a small switch with a lot of amps running thru it.

If a higher wattage heater element has been installed previously, it could have overloaded the switch & burned it out. You gotta find that switch & start there.

Thanks to all. Turns out the wiring to the external thermostat was broken where it came out of some sprayfoam insulation. Replaced that wire and all is good. Thanks again, Mark
