SOURCE: water heater will not lighr

Most likely the thermocouple which goes from the gas valve to just above the pilot light flame is bad. You can get these from any furnace supply or Lowes/ Home Depot normally. If you can depress the gas valve button and get the pilot light to light, and after holding the button in for about a minute you see it go out, then it is definitely the thermocouple.

SOURCE: pilot light on water heater wont stay lit

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.

Sounds like it is your thermal coupler. Check for a replacement part at your local hardware store. Good Luck.

SOURCE: hi we have a Ruud

Sorry to read about your problem, I hope this helps you out.

you have a defective gas control, thats the big metal unit, with the dial on it, it needs to be replaced, no repairs can be made to it.

THIS IS A GAS PRODUCT, INCORRECT REPAIR CAN CAUSE A EXPLOSION, AND DEATH CAN OCCUR. IF YOU DO HAVE THE PROPER TOOLS SUCH AS MANOMETER AND LEAK DETECTORS, I SUGGEST YOU CONTACT A SERVICE COMPANY

I stopped the device. I don't know how to restart it.

Hold in your pilot button, then push the spark button repeatedly to light your pilot. Once its lit, hold that pilot button in for 30 seconds to heat your thermocouple. once its heated, release the button, and slide the slider to burner position. Turn on hot water fixtures to get the unit to light

New thermocouple on GE/rheem water heater pilot still won't lite

does the pilot go out when you let off the button? Or does the pilot not light at all?

If you dont get any gas at all to the pilot the the gas valve is bad.
Of you get a pilot light that goes out when you let go of the button then the therno couple is not reading the flame (needs adjustment so the pilot flame touches it)
did you kink the new thermocouple? or over tighten it at the gas valve.
if it was kinked its now toast,cant straighten them. If kinked and starightened the fluid inside has broken the inner seal and wont work.

Reliance 606 natural gas water heater - model #640YORT - water does not stay hot. pilot has to be clicked to heat and then u can use hot water til tank empty and it will not continue to heat water.

If I understand correctly, the pilot light is not staying lit.
You light the pilot and water in the tank reaches temperature.
Once hot water is gone, then pilot light has to be lit again.

Gas pressure is good, and gas is flowing.
Thermostat is working at high end because it cuts off heating.
Vent is working because tank heats up.
Air intake is working.

Gas control thermostat might not be reading low temperature. Replace gas control valve.
Pilot tube might be dirty. Clean burner parts and combustion chamber, and air intake, and vent.
Backdraft might be blowing out pilot. Check for constant updraft by running water heater 5 minutes, and then light match under vent hood and see if smoke goes up.
Very hot air can put out pilot, especially when water heater located in attic. Add ventilation.
Improper vent might have water dripping back down into combustion chamber and putting out pilot light and rusting out the parts. Inspect for rusted parts and water.

I was called out because a tennants water heater wasnt working. I tried to restart the pilot. but nothing happened. I checked the gas line and it was getting gas. I checked the electronic starter and it...

if the heating element is out, the pilot will try and start , but if the thermocouple in the unit itself isn't letting the gas release,, it isn't going to fire up , Check the thermocouple , if its built into the controller valve,, your either going to have to replace that ( if its possible on that unit,, ) or get a new water heater

Water wizard 10P pilot light keeps going out

If the thermocoupler is defective the gas to everything is shut off. The coupler is the bulb that sits ib the pilot flame If it doesn't heat up it will sense no pilot and shut the gas off. They don't cost much and are easy to change. Good Luck, Ned
