I've been struggling with a gas water heater in the townhouse for over 5 days now... it's Whilpool 30gal gas burner from 2003 - not in a bad shape, but lately very problematic...
It started losing pilot flame out all of the sudden - I've tracked over there twice to light it backup but I knew there must be another problem. Finally called the 1-800 number on the label and spoke to someone who advised me that the warranty is over but they can send me a kit for free to solve the 'pilot light not staying on problem'... surely I accepted.
The kit arrived the next day - with 4 pages of instructions. It took quite a bit to get the replacement in but at the end the heater had a brand new 'innards' down in the firebox so I felt good about it. The flame stayed on, while I was there... I was hopeful...
Two days later - wouldn't you know it another phone call. Sure enough the pilot light is out again...I'm really at a loss as to what could be going on. I guess it's possible that the whole gas valve/regulator is acting up and it's time for a new water heater.
One thing that's puzzling me is this: the instruction manual for the kit installation went into great pains to insure that the firebox is well sealed. So if the firebox is sealed so well, how does it get fresh air for the flame to stay on?! Maybe the fresh air supply vent (wherever that is) is getting clogged? It might make sense, since it's having the same problem with the new kit in place...
Any advice would be welcome.

I would doubt it has a fresh air problem as you would notice it when the main burner flame kicks on then it would be really starved.
Replacing the entire gas valve is cheap and easy, there are generic ones sold at hardware stores. I am sure you already replaced the thermocouple and cleaned and adjusted the pilot flame. --98.111.xxx.xxx

Yep, the thermocouple is new as is everything else in the 'firebox' - so I'm guessing that the gas valve is the culprit.... --98.245.xx.xxx

Maybe you could first shut off gas and remove your old gas valve and take it with you to hardware store.
It really is easy to do, then again I use to work for a gas pipeline company. --98.111.xxx.xxx

Is there enough gas flow to your building? When I had a gas boiler installed the pipe into the building had to be enlarged to carry enough gas for that plus four people's gas stoves plus a 75 gal. vented through the wall hot water heater.
If the gas incoming is not enough, pilot lights will shut off I was told when they came out to put the larger pipe in.
Do you think your usage might be overloading the supply?

This may not be applicable to your problem.
But . . .
Several years ago, shortly after I purchased a 10 unit apartment building, I had a similar problem of the pilot light going out routinely.
I would go over and relight it, and everything seemed fine FOR A FEW DAYS. Then it would go out again.
What we eventually determined was that the tank (and, it was a LARGE one) had a hairline crack that would open wider when hot and allow water to drip out and extinguish the pilot light.
This was a very slight leak, but enough to put the pilot out. The heat would cause the water to evaporate, and the crack would close back up, so there was no evidence of leakage.
After replacing the gas valve, if that doesn't solve the problem, I guess you'll have to get a new water heater. After all, that one is 6 years old and they don't last like they used to.

Just called Xcel Energy (local service company) - they sent a man out to check our gas pressure to the Town house - ours is one of 4 units in the building. He (service tech) said that the pressure coming to the meter from the street was normal... no telling if there is some loss between the meter and the house, but I'd doubt it...
Tomorrow, I'll get a new gas valve from the supply house, then only time will tell if this is the culprit. --98.245.xx.xxx

Check the chimney cap. If there is not one or it has blown off it could intermittently send a draft down and blow out the pilot. Freaky weather patterns anything is possible... --70.100.xxx.xxx

I wonder if it is not a fresh air problem. A few years ago we had one that would go out and while watching the fire noticed it would begin to turn yellow and seemed to soot a little.
We worked on the area in the bottom of the water heater below the burner to allow the air to get to the fire. If memory serves me correctly, that seemed to fix the problem.

Did you transfer the burner jet from the old unit? Don't ask me why I would ask this question.
Next thing you could try is there is a brass coupling in between the gas valve and the thermocouple. Jumper it and see if the unit continues to run. --173.28.xx.xxx

Is this a Whirlpool 'Flame Lock' water heater? There was a class action lawsuit against Whirlpool...the problems were so pervasive, the evidence so overwhelming, the outlook so dim for Whirlpool that they gave in and settled...the claim period may be closed, but there may be more due you than the 800 number people care to admit. Google is your friend. --65.55.xx.xxx

I had a similar problem years ago...it went on for a month or two. I found that a spider had made a web in the gas flow line that heats the thermocouple, there was a good size flame but it was just to the side of the thermo couple. It would stay lit for a few days then go out. I cleaned the tube and the flame then hit the thermocouple straight on and it has been running for years now.
Good luck --75.35.xxx.xxx

These whirlpool tanks are the only ones out there with left hand thermocouple threads, what a dumb idea to be original, my idea is to remove the entire gas control/burner/pilot from a leaking-working tank and do the switch-a-roo, you will never look back until the water has snuffed out the flame such as Clara mentioned - and this is the main reason tanks are replaced is leaks, controls go sour once in a rare occurrence, as you might suspect I keep all control parts when I change a tank and have spares for this situation, it is a time saver to carry a couple spare controls and thermocouples. On this note I just changed a thermocouple for a brilliant engineer tenant, he asked me how can I know it is this part which failed? I took it out and sanded off the sulfur deposits and re-installed the burner rack and found it would not remain lit - you measure the dc voltage from the copper casing to the center button, if below 20 millivolts when red colored the iron has oxidized in the end of the sensing end and it is useless, this guy studying for his second PHD was amazed at my common knowledge of these things, but I reminded him I been doing this service work over 30 years. --76.241.xxx.xxx

I've had a number of pilot tubes come factory-clogged. Put a bike pump or compressor on the pilot tube and blow it out (even new ones). --128.252.xx.xxx
