How to Replace the Gas Safety Valve in Your Whirlpool Oven

The gas safety valve in your Whirlpool oven model WFG505M0BW ensures no gas is released until the igniter has reached the proper temperature. A failing safety valve will stop gas from entering your appliance, meaning your oven will not heat when the igniter is activated. To replace the gas safety valve in your oven, follow the repair guide below.

How to Replace the Gas Safety Valve in Your Oven

Before starting your oven repair, unplug your appliance and shut off the gas supply. Wear work gloves and safety goggles to protect your hands and eyes.

Open the oven door and take out both racks. Next, remove the lower access panel from inside your oven by simply lifting it up and sliding it back.
Using a Phillips screwdriver, unthread the screw securing the burner tube to the oven. Take the tube off the gas orifice and carefully set it down on the floor of the oven.
Move to the back of the oven and take out the screws holding the lower, rear access panel to the appliance. Once the panel is off, disconnect the wires from the gas safety valve, and use a 9/16 inch wrench to loosen the nut securing the gas line to the valve. Then, unthread the mounting screws holding the safety valve to the back of the range. Lift the gas safety valve up and off the oven.
To install the new safety valve, insert the orifice tube into the hole in the back of your oven. Align the valve with the gas line and reattach the two mounting screws that secure the safety valve to your appliance. Next, reconnect the wires and tighten the gas line nut with a 9/16 inch wrench. Put the lower, rear access panel back on, and reattach the screws you removed earlier.
Move to the front of your appliance and reinstall the burner tube to the safety valve’s gas orifice. Once the connection is secure, reattach the mounting screw that holds the tube in place. Next, replace the lower access panel in the oven cavity and put the racks back in your appliance.
Plug your appliance back in, and turn on the gas supply. If you smell gas at any time, shut off the gas supply and inspect the safety valve connection.
