This control valve is an important safety feature found on many gas ranges. It's located inside the back of the range near the area where the buttons and controls are found. The reason the control valve is included in ovens is to prevent gas from moving to the burners if the igniter is not able to ignite the gas or there is no electricity. The control valve could be faulty if there is a smell of gas near the valve, the burner flame flickers, or the flame cannot be turned on high.In any of these situations, the control valve must be replaced. The repair is easy and takes only a few minutes. The bottom of the oven will need to be removed, which may require a screwdriver. After removing it, remove the flame spreader by taking out two screws and sliding it out of the oven. Remove the screw holding the oven burner tube and take it out to access the valve and replace it.This control valve is made to be compatible with RCA, Kenmore, Roper, General Electric, and Hotpoint ranges. It's sold as an individual OEM replacement part that is sourced directly from the manufacturer.WB20X126 (AP2023180) replaces 251898, 337345, 4338024, AH235306, EA235306, PS235306, WB20X0126.
