I'm all but certain the gas valve on my water heater has shat the bed. It's only about 5 years old, but the pilot will not stay lit when after I release the button. The thermocouple seems to be providing the proper voltage (600 mV) when the pilot is lit. As soon as you release the button, the flame dies.

Anyway, has anyone had similar issues. It's the Honeywell Gas Valve. Anyone in town who may sell one is closed on weekends, so I can't check, but I also don't want to wait until Monday if I have no chance of finding one. The earliest I can get one shipped would arrive on Wednesday.

Stantons? The Plumbing Warehouse?

I'd replace the thermocouple first just to be safe. They're cheap and 90% of the time it's the thermocouple that's messed up.

If it's a robert shaw style valve it's almost always the thermocouple or the thermal fuse on the dampner.

If it's the honeywell valve it's almost always a fault with the valve control.


Honeywell vlaves.







Robert Shaw valves





1940's ovens with Robert Shaw valves are still going strong. Robert Shaw valves are the best, high end ovens to water heaters. Any unit with those is much better.







Thing is, you don't have a thermocouple, you have a thermopile. It can be bad, but from my experience, it's the valve itself at fault.
Now many manufactures will give a five even ten year warranty on valves. I had this happen in May with a customer. I called GE and found out he was covered. I gave them the info, they mailed him the parts, free of charge and I put them in.

It's a $200 part and only appliance parts stores would have it, I think. Depends on the hardware store.

1st source on Lobdell Blvd might have what you'll need, but they close at 1pm today.

This is the one that's up there. Trouble shooting it, I'm 99% sure at this point that it's the valve. Like I said, the thermopile is providing 600 mV, which is what I've seen people test on brand new ones on youtube.

We found that Lowes actually has a Robert Shaw valve in stock for $60, but I'm not sure if I can get away with replacing it with a different model.

I would do the warranty replacement, but how damn long am I going to be without hot water waiting for the new one to arrive?

Man, I haven't ever seen ones like the first three. Basically the same, just plastic?

This house if 5 years old. I have never had more issues with a damned water heater than I have with this on. If I can go a month without having to go into the attic and relight the pilot, I'm having a good run. Total piece of crap.

If you look online, it seems like the Honeywell valves are nothing less than a total pain in the arse.

If that's the case I'd replace it.

We've been in our house for 6.5 yrs now. Haven't had any issues yet (knock on wood) with our. There are three of them. All of our have the Shaw valves.

Have the Shaw valve. Heater went out last weekend. Narrowed it down to the thermocouple, but could not find a replacement because, Whirlpool in their infinite wisdom, used left handed threads on this model.

Soaked the thermocouple in Yamalube ring free, rinsed it off, hit it with scotch brite, threw it back in and she fired right up.

If that's the case, I'd try my best to convert it over to Robertshaw somehow

Buy a new water heater. You shouldn't be working on a 5 yr old appliance.

The problem is, it's very hard to find one without that valve these days. I was going to retrofit it with a Robertshaw, it's not that simple. The thermopile used in the new setups is much larger than a thermocouple and the voltage is much higher on the thermopile. I just waited until today to call Coburns, who told me to call the manufacturer and it would be replaced under warranty. I'll be leaving work early to pick up the new one for free.

I'm not buying a $600 appliance when I can fix it for free. That said, if I was buying a new one, I'd look for one without the Honeywell GCV. That thing is a notorious piece of shite from what I've read.

I had two of those exact valves go out on my 2 water heaters last month within 4 days of each other.

Plumber in prairieville came out and replaced them same day for $170 combined...he said they were under warranty and they do the warranty work themselves (i.e., submit for reimbursement). House is 5-6 years old.

After speaking with Coburns, they told me to call State Industries, the manufacturer, to make a warranty claim. I did that and was able to bring a reference number to Coburns, who gave me a new valve. Installed it last night and everything is working like a charm.

There you go. Bought mine from Slows, and my thermocoupler went out and they gave me the whole thermocoupler housing unit for free. Installed and bingo, hot water. Mine is going on 8.

you have to use the Honeywell or change the entire burner assemble over to the robert shaw, which is doable.

Did you check the dampner thermal fuse yet?

glad to hear. Yes always check your warranty on heaters before calling a technician.
