Question about Rheem 40 Gallon FVR NATGAS Low WATER HEATER 6YR 22V40SF
I have a kenmore hot water heater in the house that I just purchased. The model number is 153.336572. Over the past week I kept going downstairs and finding the pilot light out usually with a blinking error code. I reset it and it would work for a day or two. Today I went down to relight the pilot and there is no blinking red light indicating that it's working. I can light the pilot but as soon as I remove my hand from it, it goes out. Even in the off position there is supposed to be a red light that stays on continuously but there's nothing there anymore. I can't even find the correct replacement part online. Is there something I can do? I'm not sure if it takes a battery or if the whole thing needs to be replaced.

The water heater uses a thermocouple to generate a small voltage from the pilot light. This voltage is used to blink the led and allow the main gas jet to turn on. Either your thermocouple or the wiring from it has failed and needs to be replaced, or realigned if perhaps it moved out of position above the pilot light.

Most likely it's time to replace the thermocouple, the safety device that makes sure the pilot is lit. New thermocouples are cheap and you can find them at most hardware stores and the big-box places (Home Depot, etc.)
Here is a site with basic information to get you going.

make sure it is wired correctly, check circuit breaker, check breaker built on to element. If all fails, and it is determined your not getting power to it, you may need a electrician. Be careful. good luck.

Typically, if you have replaced the thermocoupling and are still experiencing problems, it means the master control valve is bad. It also may be a venting problem, which I would not rule out. If you call the manufacturer with model and serial number, they will be able to help you better diagnose your problem.

The thermocouple has failed. It is the temp probe that goes from the pilot lite burner area to the control valve. Go to your local plumbng repair shop and buy one. Most appliance parts stores have them also. Take the old one with you and they will hook you up with an exact replacement. They are not that hard to change. Usually a nut or 2 screws in the temp bulb area at the burner end and a nut that threads into the control valve.
Make sure before you install the new one that the area where it mates to the gas valve is clean. Should be about a 20 min job including clean up with replacement parts in hand.
