Burner Knob - Black

The first thing you want to do before installing the new gas regulator is unplug the electrical cord (power for the electric ignitors and the digital front panel) and the gas connection.
Now you need to take off the old regulator. When looking at the back of the range where the regulator is located you see three gas connection points ... Read more on the regulator- the in-coming gas, the out-going gas to the stovetop and the out-going gas to the oven. Disconnect all three with a wrench (the out-going connections need a smaller wrench than the in-coming connection) Open-end wrenches work better than a crescent-type wrench.
Next, unscrew the four mounting screws that hold the regulator onto back of the range. Now you need to move to the front side of the range and pull-out the broiler drawer.
Now you need to lie on the floor and look into the broiler area. You can see the front side of the gas regulator all the way in the back. You will need a flash light or small lamp to see what needs to be done next.
From this vantage point, you need to do three things. First, you need to disconnect three colored wires that are attached to a pin bracket attached to the gas regulator. Remember the color order when removing the wires (blue on top, orange in the middle and red on the bottom). Second, there is one more single wire to disconnect that is located to the left of the three wires (same type of disconnect). And third, disconnect the brass nut from the “j-shaped” copper flange sticking out of the front of the gas regulator.
Now everything is disconnected, almost. Now there is one final thing to do in order to “remove” the gas regulator from the range. From the back of the range, grab the regulator and pull away from the range AND at the same time “jimmy” in a few directions in order to dislodge the ‘j-shaped” copper flange from its mounting position. You might need to go back and look at this copper flange from the front to see just how this thing works.
When your mouth and tongue are in proper alignment and the proper “jimmying” has occurred, the gas regulator will be dislodged.
Now the new gas regulator can be installed.
Now, the first thing to do is mount the new gas regulator to the back of the range. Again we’re back to the notorious “j-shaped” copper flange. As you place the new gas regulator in position with the four mounting screw holes you also have to position the “j-shaped” copper flange into its mounting position inside the oven. It’s a two-fold proposition. You just have to “jack” with it until the flange is inserted in the proper position and the screw holes are in alignment.
If everybody is in-place, you install the four mounting screws. Next, attach the out-going gas connections to the regulator. Use Teflon tape or pipe thread sealant (for gas) before attachment.
Now move to the front of the range, with your light in place, attach the collared wires to the pin bracket and the single wire. Next, tighten the brass nut of the “j-shaped” copper flange. While you’re here, might want to re-check the wire connections again.
Last thing to do, connect the in-coming gas to the gas regulator.
Now you can plug the electric chord back in and turn the gas valve on.
If you don’t witness an explosion, go to the front of the range and push the BAKE button and the START button. If all went “according to Hoyle”, it’s time to cook a pizza.
Hope this helps someone.
