Review: Perfect Replacement - These Honeywell electronic gas control valves are designed to prevent serious malfunctions from causing major damages or fires, but the problem is when they detect a fault they may never work again. There are some hacks out there that may get the valve to working again but usually they are futile. desertcart's pricing for this gas control valve is good, considering free, fast Prime delivery. Beware, there are similar looking Honeywell valves on the market, some of which cost less, so make sure you are getting the correct part number for your hot water heater. The valve is relatively simple to change with minimal tools. Make sure you turn off and fully drain the hot water heater first. Since gas lines are involved you may want to hire a licensed plumber to install the valve, unless you are confident in your abilities,
Review: Good Replacement, Will Insulate This Time - This control unit is exactly what was needed to get the hot water flowing again. Status light is white and brighter than the original. Followed Honeywell directions that said no pipe tape sealant on supply side. Compression fittings don’t need tape either. Leak checked and no problems. A small length of pipe screwed into the supply side makes for a convenient handle to remove the old unit and screw in the new one without damaging it. Quick and easy. Good deal. The failed unit was only 4 years old but I suspect the wild ambient temperature swings where it is installed caused the unit to fail. This time I will insulate it to make it last longer.

### ⭐⭐⭐⭐⭐ Fits State GS650YBRTG 300
*by C***M on March 4, 2021*

My original gas control valve was giving me the 5-blinks of death. The replacement is identical to the original except the name - instead of Honeywell, it is Reliance. I used a 5" piece of gas pipe threaded into the gas inlet as a torque handle to break free the old gas valve, once I broke it I used a smaller nipple to remove it the rest of the was. Installation was the reverse. Remember when installing the new one to put Teflon tape on the threads and tighten BETWEEN 4-6 TURNS. I tightened to 5 turns. No leaks, no drips and no errors! We have HOT water now!!!
