400 Series Honeywell Electronic Gas Control Valve

After a good cleaning under the burner assembly, and replacing the pilot assembly, and still not able to keep the pilot lit, I tried replacing with this valve. After being without hot water for several days, the valve arrived, only to discover during installation that the threads for the copper pilot line weren't right. Correct size, but the connector would only screw in crooked, and therefore would leak gas. It was like they had been previously cross-threaded. Amazon quickly sent out a replacement. It showed up two days later, installed without issue, and voila! It has worked flawlessly for a couple of weeks. Where I live, there is no local company that will sell you appliace parts if you're not a contractor. While same-day isn't an option, being able to purchase thid from Amazon saved me hundreds of dollars having to hire a repair person.

I received the item in a fair amount of time. Installed and my water heater problem got fixed.

Bought used for half the price. Someone definitely had roughly installed it before and left marks but it works. Make sure and drain your tank first. Also, while you’re in there get a scrub brush and vacuumed and clean out the air vent under the burner they get clogged with dust and prevent the burner from getting enough oxygen. Waiting for the tank to drain adds extra time. Probably took an hour total, then the water heater worked better than ever! Check for gas leaks and reset /recalibrate the temperature settings.

I really liked how prompt the seller was about answering questions so I was sure to get the right part. Reasonable price, so far its only shut off on me once. I lowered the setting between low and hot and hopefully it won't happen again. I've had the hardest time with my water heater this last year. Finally we can use the hot water and not worry about the water being cold! Perfect fit, exact part I needed. I did not DIY this installation I hired a professional to install it.

I knew going in that the product may have been previously installed; however, what I didn't know, and I don't think that the seller knew that there was an issue with the product. Upon receiving the valve, I did a thorough inspection and found that the thermostat on the rear was cross threaded. Having worked in maintenance and being a skilled tradesman, I was able to correct the issue and get the item installed. It works like intended so I have no complaints. Thank you.

Le quedó muy bien lo busqué en muchos lugares y hasqui en pocos días llego

Installed 3 years ago and had no problems

I purchased the gas control valve in December, had it installed in mid January. It failed to regulate the temperature of the water in the tank, causing it to oveheat and drip from the tube. Plumber came and said that the water was too hot, heater kept running, and that it could be a safety hazard. Amazon said that the return period was over by 2 weeks and that I should call AO Smith because it should be under warranty. AO Smith indicated that since I purchased this item from Amazon, that it is not covered by the warranty. I will be cancelling my Amazon Prime account.
