Hello Bill The temp stat is a square box clipped in under the elements .Can be replaced in 5 minutes.Need a large flat screwdriver.
SOURCE: New water heater installed in Jan.2010, first no
The reset switch works like a thermostatic breaker and although unusual, it is possible the reset switch is bad or weak. You can replace the reset but some are hard to find. It may be easier to replace the upper thermostat with reset. I would also suggest that you check with the vender you purchased it from, and relay your story to them as they may be willing to help you with the parts. I hope this helps.

You will need an amp meter. I suspect that the lower heating element is out or the thermostat.
Most water heater have a upper and lower element. The bottom is the main work horse.
Take the lower access door off and you can get to the wires to use a clamp on Amp meter. You should get a reading of 10 + amp if it is working. You can check the thermostat with the volt meter also to make sure you are getting voltage to the element . You should have 220 volts across the two wire attached to the element. The elements are not to hard to change. You will need to shut the power Off and the Cold Water off. Drain the tank to get below the bottom element and you will need to get a special wrench to unscrew the old element out of the tank. Hope this Helps
Testimonial: "Thanks for the promt reply, I had the feeling it might be that but did not know how to find out. Thanks again"

If you have some hot water from dual-element water heater, then that tells us:
Water heater is 240Volt.
Upper element is working. If upper element is not working, then heater has NO hot water.
Reset button is not tripped.
Electricity and breaker to water heater are delivering 240Volts to heater.
Remaining suspects are:
1) Bad upper or lower thermostat: Solution: replace both thermostats for 28$.

2) Bad lower element: Solution test and replace element:

3) Loose wire or loose connection: Solution: open both covers and inspect for burning. Tighten all screws very tight.
4) Bad wire: Solution: Buy cheap multimeter from Home Center and do a 30 minute troubleshoot of entire water heater before replacing any parts:

When testing for voltage, rotate multimeter dial to 240-250-277VAC
When testing elements or continuity, rotate multimeter dial to Ohms.
it is important to turn off
the gas supply to the water heater at the manual gas shut-off
valve. This valve is typically located beside the water heater.
Note the position of the shut-off valve in the open/on position
then proceed to turn it off.
2. On the lower front of the water heater locate the combination
gas control valve/thermostat. Depress and hold
the lock tab located under the gas control knob on the right.
Rotate the gas control knob on the combination gas control
valve/thermostat clockwise until "OFF" aligns with the mark on
the front of the gas valve. Once the gas supply has been shutoff,
remove outer door. 3. Using a 1/4" nut driver or socket loosen the two screws securing
the manifold door assembly until they are free. Do not
totally remove the screws and plastic retainer washers from
the manifold door. The screws and retainer washers will be
needed to reattach the manifold door. 4. In this step, the thermocouple, manifold tube, pilot tube and
igniter wire will be disconnected from the combination gas
control valve/thermostat. Using a 7/16" wrench
disconnect the thermocouple (left-hand thread) and pilot tube
(right-hand thread). Using a 3/4" wrench disconnect the manifold
tube (right-hand thread). Carefully pull the igniter wire from
the igniter button.
5. Grasp the manifold tube and push down slightly to free the
manifold tube, pilot tube, and thermocouple from the combination
gas control valve/thermostat. when installation is complete and gas is back on, You should be able to relight the pilot and the functionality of your gas hot water heater should be restored.
