## Description

Please feel free to contact us directly to determine if this is the correct gas valve for your water heater!!! We will need the model and serial number of the water heater to cross reference properly. The electronic gas control valve incorporates an LED status indicator that monitors system operation and service diagnostics. Gas control located within hot water heater uses a thermopile to generate the power needed to operate the electronic gas control without requiring an external power source. This product has been certified by a third party to be compliant with the “Safe Drinking Water Act” requirements for low lead in potable (human consumption - drinking and cooking) and non-potable water applications (non-human consumption). Thermostat is compatible with all A.O. Smith branded heaters including A.O. Smith, State Water Heaters, American Water Heater, Whirlpool, Craftmaster and Reliance. Product manufactured by Honeywell for A.O. Smith. Honeywell model # WV8840B1158. Please be aware part may come labeled RESIDEO as there was a corporate acquisition. It is still the correct Honeywell part!

Review: I received the item in a fair amount of time. Installed and my water heater problem got fixed.
Review: 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. desertcart 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 desertcart saved me hundreds of dollars having to hire a repair person.

*by A***D on 25 April 2025*

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.
