Model G-40T2-3-6 NAT

Replacing a heat element in this model is a good idea if it's bad.. Otherwise I would suggest changing the part that is defective. ;-)

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/perry_14036f9bc71cde6a

follow this test and use the multimeter and fix it. God bless you
If there is no hot water, first push the reset button on the high-temperature cutoff; test the thermostat and replace if faulty (see below). Test the heating element(s) and replace if faulty
.Test and replace a heating element:

1. Turn off power at the electric panel and post a sign warning others not to turn it on.
   
2. Remove the access panel on the electric water heater.
   
3. Disconnect one of the element wires and set a multimeter to RX1000 (resistance times 1,000). Touch one probe to an element mounting bolt and the other to each element terminal screw, in turn. If the tester displays anything but infinity ( open circuit), replace the element.
   
4. If necessary, set the multimeter to RX1 and touch the probes to the terminal screws. If there is any resistance reading at all ( closed circuit), then the element is good. If not, replace it. Both upper and lower elements are tested in the same manner.
   
5. To remove the element, first drain the heater.
   
6. Disconnect the remaining element wire. Remove the mounting bolts holding the element in place. Remove the element.
   
7. Replace the heating element with one of the same model, shape, and rating. Make sure you also replace any installation gaskets.
   

follow this steps and fix it. God bless you

Troubleshoot a thermostat:

1. Shut off power to the heater at the electric panel and post a sign warning others not to turn it on.
2. Unscrew and remove the electric water heater access panel.
3. Using a small screwdriver, turn the thermostat dial counterclockwise to lower the temperature, or clockwise to raise it. If the water heater doesn't maintain the proper temperature, test the thermostat.
4. Disconnect one wire to the upper thermostat to test it. Set a multimeter to RX1 (resistance times 1) and touch a probe to the thermostat terminals as indicated in the owner's manual. Depending on the model and the terminals tested, the tester should show infinity ( open) or about 0 ( closed).
5. Test the lower thermostat in the same manner.
6. If necessary, replace the thermostat. Unscrew it from its mounting and install one of the same model, size, and rating. Once you install it, adjust the thermostat following instructions in your owner's manual.

Test and replace a high-limit cutoff:

1. Disconnect power to the heater at the electric panel and post a sign warning others not to turn it on.
2. Remove the upper access panel and push the reset button.
3. Replace the access panel and turn the power back on. If the water is hot, the reset was the problem. If not, you'll need to turn the power off again and reopen the access panel.
4. Use a multimeter to test the cutoff terminals for continuity. If faulty, replace with an exact replacement part.

1) Test elements,and if elements are good, replace both thermostats
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

2) Test across top two screws on upper thermostat for 240Volts.
If this test shows 240V, then no more voltage testing is needed.

Question posted under Rheem water heaters
Rheem parts guide does not show that part number with either flanged or screw-in type.

If this is ordinary tank-type electric water heater, copy following link to see step-by-step.
http://waterheatertimer.org/How-to-replace-water-heater-element.html

Otherwise, add a comment or re-post question and include type, brand and model of water heater as shown on product label.
For example Atwood, or Under-counter, solar-assisted, tankless etc.
