Why convert your GE range from natural gas (NG or NAT) to liquid propane (LP)

The majority of oven ranges today use natural gas (NG or NAT). However, it’s possible to convert most range models to use liquid propane (LP) instead.

Some families may choose to do this to save money on cooking gas, as propane is typically more efficient. In fact, every unit of propane contains twice as much energy as natural gas. In other words, you’ll only need half the gas to do the same amount of cooking.

Propane gas works at a much higher pressure than natural gas, which is why you’ll need to make adjustments to both the burners and the oven to prepare your range for LP use. To do this on your own, you should purchase an LP conversion kit and follow our instructions carefully to safely install it.

How to buy the correct LP conversion kit

GE makes several different LP conversion kits based on the range model. You should check your operator’s manual to find the part number for your specific oven range.

One of the most popular kits for GE ranges today is the LP Conversion Kit WB28K10556, which we’ll be using for our guide today. However, you can check out other available gas conversion kits on Appliance Parts Pros.com. Simply look up the part number in your operator’s manual or search by your oven range model.

How to install an LP conversion kit in a GE range

Warning: Unplug your oven and turn off the gas to your range

It’s important to stay safe as you work on your GE range. Before you begin, be sure to unplug your oven and turn off the gas to your range, so there’s no risk of electrocution or gas leaks as you complete installation.

Part 1: Convert the burner area to LP

Main task:

• Replace the old burner orifice spuds with new LP spuds.

1. Open your LP conversion kit

To get started, open your LP conversion kit and take out the four LP orifice spuds. These spuds control the amount of gas entering the burner. Since LP gas burns at a higher pressure, your new spuds have smaller sized holes.

We’ll start by replacing the four existing orifice spuds with these new LP orifice spuds. The idea is to take off the old spuds and mount a new one on each of the four burners.

2. Take off the burner grates, burner caps and burners

To reach the gas supply tubes where the orifice spuds go, first take off the burner grates, burners and burner caps. Once you do, you’ll see the four orifice spuds in the very center of each burner.

3. Use a 9/32 ratchet to remove all four old orifice spuds

Use a 9/32 ratchet and place it over the orifice spud. Unscrew it by turning it counter-clockwise. Do this for all four burners.

Pro tip: You can more easily remove the old orifice spuds by using a small wad of masking tape and placing it in the head of the ratchet. It will stick to the spud and aid in the removal process.

4. Install all four new LP orifice spuds using the 9/32 ratchet

Now, you can take your new LP orifice spuds and install them using the same 9/32 ratchet. Place the spud in the ratchet head and screw it onto the gas supply tube by turning it clockwise.

Don’t screw on the spuds too tightly. When the ratchet naturally stops turning, that’s far enough.

5. Reinstall the burners, burner caps and burner grates

You can go ahead and replace the burners, burner caps and burner grates as you found them. You’ve now successfully converted the burner area to LP – now it’s time to make some adjustments in the oven area!

Part 2: Convert the oven area to LP

Main tasks:

• Reverse the pressure regulator cap.
• Tighten the bell orifice.
• Adjust the air shutter for LP gas.

1. Remove the oven door and racks

Next, it’s essential to adjust a few areas of your oven to handle the pressure of LP, including the pressure regulator cap, bell orifice and air shutter. All these elements are located inside your oven, below the bottom panel.

To reach this area, you must first remove the oven door and racks. For the oven door, open it partially, then grab it by the sides and lift it off its hinges. Be careful not to break the glass of the door during this step.

For the racks, simply pull them from the rails and lift up.

2. Use a 1/4 nut driver to remove the two screws on the oven bottom and lift the panel out

Let’s now take off the oven bottom. There are two screws located towards the back of the oven that you must remove first. Use a 1/4 nut driver to loosen the screws and take them out.

Next, you can lift up the oven bottom. We recommend doing this with work gloves, as the cutouts can be sharp. Lift the panel up using the cutouts as holds. You must first lift the back and then raise it over the front lip.

With the oven bottom removed, you can now pull the broiler pan out 6-10 inches and reach the back of your oven.

3. Use a 1/4 nut driver to remove the protective shield

Once you can reach the back of your oven, you’ll notice a protective shield. You must remove the shield by loosening a single screw on the bottom right of the shield. Use a 1/4 nut driver to take out the screw.

You can then remove the protective shield by sliding it to the right and lifting it out from the left cutout.

4. Use a 1/4 nut driver to remove the three screws of the central burner

You still have a few areas to remove in order to reach the pressure regulator cap, bell orifice and air shutter. Let’s now remove the central burner. This burner has three screws to loosen: one in the front and two in the back.

Use a 1/4 nut driver to remove the screws by turning counter-clockwise. You can now partially pull out the burner by pulling on the wires gently, lifting the burner up and setting it down on the oven bottom.

5. Fully take out the central burner by disconnecting the two connectors and plug.

The burner is still connected to the unit with two connectors and a plug that’s hidden from view. You must remove these items in order to lift the burner completely out of the oven.

To reach the plug, you must first remove the plug cover. Use a 1/4 nut driver to loosen the screw and remove the cover.

You can now pop up the two orange connectors. If you need leverage, simply use a flat-head screwdriver to lift them up.

Next, you can pull the plug through the opening of the hole. To open the plug, simply push down on the tabs. Now the burner and igniter assembly are free and you can remove them from the oven.

6. Use a 5/8 wrench to unscrew the cap from the pressure regulator

At last, you can reach the pressure regulator. Here you should unscrew the cap in order to reverse it in the next step. Use a 5/8 wrench to unscrew the cap and lift it out.

7. Reverse the pressure regulator cap and reinstall it

Pay attention as you reverse the cap, so that you install it facing the correct way. Take off the plastic cover, turn the cap over in your hand and replace the plastic cover on this new side.

Pro tip: The pin of the cap should now be facing down into the pressure regulator opening, as pictured above. This will increase pressure on the membrane for LP use.

Go ahead and replace the cap and screw it back on using the 5/8 wrench. Don’t overtighten the cap. Simply screw it on until it naturally resists. Add the plastic cap back on as well.

8. Tighten the bell orifice one full turn using a 1/2 wrench

Our next adjustment is for the bell orifice located on the safety gas valve. Use a 1/2 wrench in order to tighten it one full turn clockwise. This will increase pressure for LP use.

9. Adjust the air shutter on the central burner to LP gas

Our final adjustment involves the central burner that you already removed from the oven unit. Use a Phillips screwdriver to adjust the screw on the head of the burner. Go ahead and loosen the screw (but don’t remove it).

Next, you’ll want to turn the head until the screw is located under the “LP” initials on the burner. Once the screw is in the right position for LP, you can tighten it again.

Important note: If you have a separate broiler, you must follow this same procedure to adjust the air shutter and bell orifice to LP. 

10. Restore your oven to its original state

You’ve completed the three key adjustments for the oven area – nice work! Now you’re ready to reinstall all the parts you removed during the repair process. To restore your oven for use, you should:

• Set the central burner on the oven bottom and connect the plug.
• Thread the plug and wires back through the hole.
• Reattach the two connectors (it doesn’t matter which goes where).
• Reinstall the plug cover and tighten the 1/4 screw.
• Place the central burner back in the correct position by setting it over the bell orifice.
• Reattach the three 1/4 screws of the central burner (one in the front and two in the back).
• Reinstall the protective shield by matching up the holes and fastening it with the 1/4 screw.
• Push the broiler pan back in.
• Reinsert the oven bottom by setting in the front lip first and lowering it towards the back.
• Reattach the two 1/4 screws of the oven bottom and tighten them.
• Add the oven racks back by placing them on the rail and pushing them in.
• Reinstall the oven door by gliding it onto the hinges, then opening the oven all the way. Now slowly close it.
• Plug in your oven and turn on the gas to your range.
