Tip & How-To about Kenmore 40494 / 40495 / 40499 Electric Single Oven

Changing your gas appliance from natural gas to LP or vice versa.

You have an LP gas stove which you really like and would like to take to a new home but the new home has a natural gas hookup. Since natural gas is already available it would be convenient to be able to use it. Can you convert your unit over to work on natural gas?

Yes it is possible to convert any LP gas appliance to natural gas or from natural gas to LP. The only difference is the size of the orifice used in the burner.

LP gas is composed of a much larger molecule than natural gas and requires a larger orifice to output the same amount of gas as a natural gas unit at the same setting. Therefore if you used an LP stove on natural gas it would produce too much heat and burn rather intensely. If you used a natural gas stove on LP it would not have much flame at all. You can see the problem. The solution is also obvious. You need the correct orifice.

Changing the orifice is easy. It is located in the middle of the burner and unscrews out of the unit. Install the new one the opposite way. Do not overtighten it.Usually the burners are made of soft metal and can strip easily.

The parts you would need are available at most good appliance stores but I would recommend the following site http://www.repairclinic.com . The parts will be cheaper at repairclinic. They have parts for almost any brand and a great search engine. They also have excellent videos showing how to make the repair.

Thanks for using FixYa and for the great rating.

how to connect a natural-gas kitchen oven


Most localities require that a qualified professional make these LP and natural gas connections. This is often someone that holds a license of some sort - most often it is a plumber.

Failure to ensure that the connection is leak free and meets local & state codes could be disastrous - if not deadly. Saving a few bucks isn't worth the gamble.

I will soon need to convert a 1993(?) CALORIC Kitchen Range back to Natural Gas from LP. When I installed it, NG was not available, so the propane company guys converted it to LP. I was not here to learn how they did the conversion and I do not have any instructions. Amana and Whirlpool say they have no info on that range, even though they have taken over control of Caloric. Any idea what I need to do? Thanks! in advance.


First check the regulator valve on the back of the stove. Chances are it is a dual purpose valve and once you are ready to do the converstion.. you simply will move the lever or change the setting from LP to NAT.(obvisouly before proceeding you need to have the fuel supply turned off to the appliance)

Next check under the range lid or on the back of the stove for the spare NATural gas orifices.. when they changed it out for you there were two scenarios.. the range (most do) came with a set of LP orifices..and they simply changed these out on each burner supply including brolier/oven. (orifices are interchangeable nozzles that are threaded into the supply gas burner)

If they had to swap out the regulator chances are they would have given you the one that came with your stove.. However I am fairly sure the regulator is a dual purpose and you simply need to change the setting from LP to NAT.

DO NOT DO THIS WITHOUT CHANGING OUT THE ORIFICES FIRST.

If you cannot locate the spare orifices/spud/nozzles (they are called all of these) on the stove itself you will need to buy a set. A good appliance parts store will be able to help you with these.. again.. you will need one for each burner/burner supply.

If you can locate the range manual it will have instructions on how to do this.

Chances are your Natural Gas company will be able to help you with this.. especially if the regulator is dual purpose.. even if you can't find the orifices they are inexpensive.. fairly standard and easy to acquire. Usually just called a "conversion kit".. it will just consist of four or five small threaded 5/16 brass nozzles/orifices.
The installation is pretty straightforward. Again..a good appliance parts store may recommend a service company...and if your not familiar with diy repairs on a gas appliance.. a 50 to 100 dollar service call is well worth the money.

Best of luck to you!

Recently purchased Frig. gas stove.Want to convert from natural gas to Lp.Do you remove spud and insert Lp oriface in spud then screw spud back onto line?Lp oriface is a lot smaller than oriface for natural gas and will not screw into line itself. Thank-You P.S. The 2 orifaces I have to convert are for the oven & broiler.


Not really sure which model you have but when converting the over, ether bake or broil burner you tighten down the orfice cap. If you remove the burner off the oven valve you will notice that you can put a wrench on the orfice cap. Just tighten snuggly. If you over tighten you will crush the orfice under the cap.

converting aan LP oven to gas


In most cases the pressure regulator has to be changed or adjusted. The orfices on each burner, oven, broiler and surface burner may need to be changed also. Sometimes they can be adjusted. Sometimes the threads on the pipe are different also. This is to prevent accidental connection to the wrong fuel. The big difference is the gas pressure. LP is usually around 10 - 12 lbs and natural gas is usually around 3 lbs. Properly adjusted you will like natural gas much better than LP as it is slightly hotter. The information will be in the instruction book and also on the Jenn air web site. Whirlpool owns both Maytag and Jenn aire so check all sites. The conversion kit is usually less than $50.
