Hello,It likely is having a problem in the header. There are two items called High Limit switches in there, that open when a preset water temperature is reached. These can go bad, or they could be opening because they are doing their job. Based on your description, they are doing their job. I would start to look for a problem with the heat exchanger and with the internal bypass assembly as my starting points. These can cause an overheating situation.
This unit runs off 120VAC. With a multimeter check for voltage going into unit, at thermostat (control on front of unit), then at each sensor (flow switch, follow the wires, then temp limit switches (2), then air pressure sensor, then to fan & ignition board). I'm betting one of those sensors is bad or sensing something wrong. Do you have enough flow? .. You should check to see if the heater is getting the proper voltage. You will need a multimeter to do this. Depending on which model of heater you have, you will see conduit coming into the heater, this is the power supply. It will usually come from the time clock or be wired into the pump relay depending on your exact situation. Where the wiring goes into the heater, you should be able to read 120 or 240 vac, depending on how your heater was installed. IF YOU ARE NOT COMFORTABLE WORKING AROUND ELECTRICITY, DO NOT ATTEMPT THIS!!! 240 VAC IS ALOT OF ENERGY AND CAN CAUSE YOU SERIOUS INJURY OR EVEN DEATH. If you are not getting the proper voltage at this point, then the problem is not with the heater, it is with the supply line. If you are getting the proper voltage, then you would need to check further. That power should then go to an interlock switch depending model of heater or straight to the transformer. Make sure you are getting the same reading into the transformer and out of the transformer should be 24vac. +- a few volts. That is a starting point, and should be able to get you in the correct direction.
remove the plastic side where the controls are . if you see a broken wire you might be able to repair it otherwise theres no parts made for it ,so no matter how simple the broken part is .....there is nothing that can be done about it ........ WELCOME TO THE WORLD OF "MADE IN CHINA"

If this is a milivolt heater or electronic ignition you will find the pilot just left of center on top of the burners. If a milivolt heater you can follow the gas tube from the main valve to it. Then follow instructions on the inside of the door on how to light. (Push the dial down on the gas valve in the pilot position while lighting. Hold for a minuit then turn back to open. If electronic you should just turn the heater off for a minuit then turn back on and you will hear a clicking as it automaticly lights. If this is a glow plug this is recessed into the face of the cabnit dead center over the burners. When you shut this off and turn back on the fan will start and then you will hear a very small click from the control box. If you can look inside the burner box you will see this glow white hot. There should be a small (1/2" round) hole to look for this. If you don't see this glowing it could have gone bad. Many things can cause this. A water drip, a hadr bump to the unit... You have to find what caused this before changing it out or it can happen again. If you reach into the reses this sits in you can unscrew the two nuts that hold it in place with a nut driver. Follow it back and unplug and install new one. I believe they came out with a tougher one but if it comes in a box settled in foam rubber you got the frail one. Be very careful with this as it is ceramic and very easy to break. When at the store buying this take it out of the box and be sure it isn't broken when you get it. Also be sure the power is off at the breaker when you do this as it has secondary power running to it even when the clock is off. A lot to dump on you but I read some of the solutions you got and felt I should get you all I could give you since I usually only get on line on Sunday anymore. But you will only have one of these types of heater. Nevermind that made in China and throw it away ****. You can always fix it. http://www.haywardnet.com/inground/products/manuals.cfm This is a web site that will get you to most Hayward manules.

Take care.
I just need to know where the pilot light is so I can re start the heater....It blew out
remove the plastic side where the controls are . if you see a broken
wire you might be able to repair it otherwise theres no parts made for
it ,so no matter how simple the broken part is .....there is nothing
that can be done about it ........ WELCOME TO THE WORLD OF "MADE IN
