My water heater is about 6 years old and started to lose its ability to maintain a lit pilot. For a few days, I had to run down to my garage and check to see if the pilot light was still on before taking a shower in the morning. After reading several forums and researching the problem, I found out that the issue was likely one of two things: either the filter into the combustion chamber was dirty and wouldn't allow for enough air to maintain the pilot light or I would have to replace the thermocouple.

I first tried to replace the thermocouple but upon inspection, I realized that due to the fact that this was a newer FVIR type unit, the universal thermocouple replacements typically found in hardware stores wouldn't work. This unit had a disc between the copper line running to the control unit and the thermocouple itself. I decided to give the cleaning a try and cleaned the filter below the water heater. That proved to be a tough task as the space underneath was very limited. Still, I did what I could and while the pilot light remained lit for a couple days, it still went out in the end and continued to do so with more and more regularity as the days passed.

I wasn't able to find a replacement part for just the unique thermocouple itself so I searched for burner replacement units but those were a little pricey at around $65 on up into the hundreds. By chance, I found a link to this unit when searching for a replacement on Ace Hardware's page. Amazon, of course, had a lower price and since Ace didn't stock the item in store anyway, I decided to place my order here. This unit included the thermocouple, a new gasket (great since the water heater warns that the gasket should be replaced every time the current one is removed) and the gas line for the pilot. The replacement worked perfectly for my State Select GS640YOCT water heater. The lines were a little longer than the OEM model but I simply ran those tucked out of the way. I've now been free of issues for the past three weeks.

Took a chance, and this part is also a direct replacement to AO Smith 9003542005 at almost 1/3 the cost. My part shipped and recieved the next day. Took 30 mins to install.

This thing is almost exactly the same as what was in our
AO Smith model# GCV 40 100 water heater. Right down to the markings stamped on it (pretty much, anyway).
The only thing wrong with the old one was the resistor wire had
cracked and was not making contact. That will effectively disable
the water heater, so that pilot light won't reliably stay lit.
Multiple cleanings and fiddling with it before I discovered
the cracked wire connection. Goodness, WHAT A HEADACHE fooling with this thing, trying to "fix" it!!
If your old one has the same problem, you may be able
to temporarily fix it like I did mine; bend the wire so it has some pressure
to "hold" itself in place and make connection. I ordered this new part
and after it arrived, waited to see how long my temporary fix on the old one was going to last.
It quit today, around 2 months in. I installed the new assembly shown for this product listing in about 15 minutes,
skipped the new fiberglass seal changeover, and BAM, right back like new.
This part was replaced under warranty 3 years ago by our plumber so it is apparently "failure prone".
i plan on milking all the life out of the heater that I can, so to avoid waiting on the next failure
and ordering the part, waiting on arrival, cold showers...
I'm ordering another for backup. TODAY. It won't go bad, and 35.00 is cheap insurance to have
for ensuring I'm no more than 15 minutes away from a repaired water heater.
If Momma ain't happy, ain't nobody happy. And I fall under the nobody category when things are broke.
So, to sum it up: Good part, easy to replace, at least if you're mechanically inclined and a lot cheaper than a plumber plus parts
through them. Fit my AO Smith heater like a champ, and it works. What's not to like for this handyman??
Highly recommend!!!!

I received the item in 2 days with Amazon Prime. In addition to what you see it also came with a filter screen and replacement door insulation pad. All fittings, screws, etc were an exact match to make the replacement quick and easy. The plumber quoted a price of $250. I was able to do it myself for $34 and 20 minutes. I did google a youtube video that helped a lot. [...]. I don't know what other water heaters it might work with but it was an exact replacement for the AO Smith GCV-50 100.

I needed to replace my pilot assembly on my water heater... And this was perfect for that! After I received the quick shipping (LOVE PRIME!) My hubby and son installed it in a matter of minutes and we were back in business with our hot water! Thanks Amazon for having it here for me to purchase! :o)

The Reliance Water Heater #9003542Nat Gas Pilot Assembly worked perfect and was easy to install. I purchased the product through Amazon and they provide several vendors to select from. That gives you the opportunity to order from the closest and the one that provides the best deal for you.

Installed this item within 1/2 hour and it took a little bit to get the pilot light to stay on, but once on it worked for 4 to 5 weeks until it flamed out. Had great difficulty trying to get it to light again. Contacted Grady's via Amazon email link and the vendor responded the very next morning. They are processing a replacement at this time. No hassles. Definitely, a reputable vendor. I would recommend and purchase from this vendor again despite the inconveniences.

The item received on time and included not only the items shown in the picture but also instructions. It was simple to replace the old part and after 20 minutes the heater was working again. Wouldn't hesitate to purchase again from this seller.

I was sceptical till the product was delivered to me. I could install it without any professional help and the part is functioning very well till now, for approximately 2 months.

Worked perfect on my Select State natural gas water heater then intermittently started not staying lit after about 2 months. Now at the 3 month mark as soon as the burner turns off the pilot light goes out with it. Exactly what happened with the original except the original lasted 9 years.
