Th epproblem you are most likely have is from a safety called a flag switch usually located either in the blower or right past it. When you unplug and replug you reset the switch. Sequence of events.
1 fan comes on.
2 switch is made from the airflow of the fan.
3 ignitor come on
4. main gas valve opens and ignitor starts flame.
You are being stopped at step 2 when the fan does not move with the air. This shuts off and out the water heater from calling again. Find the fan switch and make sure it moves easily. They get dirty and also dry from lack of lube.
Good luck.

I have the same problem. Water heater operates on a very simple principle. of thermo-mechanical feed-back and response. In my case, I have a Kenmore Power Miser 6, NG heater with an electronic pilot ignition system. The heater is just over one year old and last month (conveniently just after the 12 month service warranty expired) the pilot light started extinguishing on a very regular basis. I find it interesting that the very problem I am experiencing, is happening to other Kenmore owners (victims). The solution can be found in replacing one of two possible components; the pilot assembly or the gas valve manifold. The price of DIY pilot assembly replacement is approx. $60 . The valve component is significantly higher. Water heaters are designed and built to provide years of trouble-free reliable service. This is the first Kenmore product I have owned. From a customer perspective, with regard to product performance, Sears/Kenmore needs to take a strong look at their supplier quality. Oh, by the way, contacting Sears for remedial relief only managed to frustrate and infuriate me. You see, I am in Quality for a world-class aircraft company. I understand what ethical steps are required to satisfy a valued customer. I plan on ripping out the defective unit this weekend and replacing it with a reliable Home depot special. At least with HD, if the heater fails to perform , I can return it. Hey Sears in Chicago, don't come crying to the consumer when you are looking for the trendy "bail out".

It is most likely the water valve stuck open, telling the controls to heat water, that it thinks is flowing through it, but without actual flow it overheats. Depending on how comfortable you are with taking it apart yourself, you could open the valve to see if it just needs cleaned out, or if you have a ruptured diaphragm or some other cause.

Thermo coupler may be defective. it controls the main gas valve by closing main if pilot is out. make sure thermo coupler bulb is positioned over and near tip of pilot flame, but not in the flame. Thermo couplers are inexpensive and easy to change out.
