Water heater (Gas) not working


Chaz, yeah dug out and now another big storm Mon. Moosehead sounds good, i average, AFTER fishing, 17/18 Miller Lites......CPRA, you must live by yourself [no female/kids] how you coping with no hots for a week???....that little thermo -'thingie'-will shut off burner and pilot if it's tripped. pilot will go right out after you release button. to reset just push little button, in middle of thermo,= in. if you take access door off -gasket is critical- must be in perfect condition and replaced/reinstalled per manf instructions.....i've seen films of gas hot water heaters when they blow--takes the house with them, so be careful.

Depending on how it's wired, you may be able to jump past the thermocouple safety just to verify that the pilot stays lit. If memory serves, it's more of a mechanical thermocouple on gas units, and you may not be able to "fool" it. Anyways, you can't leave it that way--just long enough to test it.
that is correct. It's a (Thermo)-Mechanical device. At the other (inside) end, the copper wire is connected to a Bi-metal strip. When the heat of the wire reaches the strip, it opens the gas valve for the pilot. Provided it functions properly. Otherwise, it has to be replaced. The main burner has its own set of protection/s. When the Thermostat calls for heat, it must go through at least Two safety checkpoints. The Pressure 'Trol and the low water cutout. They're connected in series. And if there are no issues with high pressure or a low water level, the gas valve for the main burner is ready to open up.!

I put the new thermocouple but it still does not work.. I tried 3 times, pilot gets on but does not stay once I release the button

I think now it is time for me to call a service guy..

I agree. But what you gained is a well rounded lay-person's knowledge of the workings of the hot water system. There may be some gas-flow issues (at the valve or the t. couple itself.) that are best left to an experienced service person.!

Quick update. Called the guy.. He changed the input gas connection and started working..
I am just running out for Costco. I will come back and provide more details with pics about what he has done.

Here are the pics.

http://i699.photobucket.com/albums/v...r/TRPvalue.gif

Earlier the gas connection from the main value was not directly connected to heater burner. It was connected to a TPV value and from the TPV value it was going into water heater.

He says that is wrong and not as per the code. It should never be connected to TPV value. Since it is connected to TPV value the gas is getting mixed with water or water vapour. He says there should not be any input to TPV and there will be an output which should get connected to Drip line.. It works if the temperature in the heater goes high... it should allows water to get out of the heater..

What he says is logical to me,, at the same time, the connection has been like this since I moved into this house for the last 6 months..
I guess this problem was created by me when I moved the thermostat to
"HOT"..

What do you guys think ? I can't say for sure who installed this machine earlier..

that is UNBELIVEABLE! just goes to show what happens when you try to solve problems on the internet with certain assumptions, ie; that it's installed properly. what in the world was the original installer thinking...you should send these pic's to Bradford White... glad you got it fixed properly.

So do you think, the current connection was right ?

Yeah, kinda' like Edison's lightbulb--we now know twenty-five ways not to fix a waterheater...plus no one died in the process!

Hey cprao, thanks for giving us the detailed followup . It's very helpful. Too many people ask questions, get advice, and then they are never heard from again. Good learning experience for everyone.
