kenmore elite gas orifices

by Manage My Life Last activity date:
September 9th, 2011

I purchased a used 790.75503 201 and now that it is connected to natural gas, the burners all have a very small flame. I am suspecting that this unit was used with propane. The seller did not indicate which fuel was used. I have removed one of the orifices on a "power" burner and it has little numbers stamped on it. On one side it says "L" and there is a "101" on the other side. Can you tell me if this is an LP gas orifice or a nat. gas orifice?

Also, there are 4 different nat.gas orifices available on parts direct

Do you know why there are 4 models? Are the different models for the simmer burner and/or power burners? There are two standard burners, two power burners, and one simmer burner.

We need help determining which orifices to buy if we have the wrong ones. Please reply.

Your description does indicate that the range has been converted to LP gas. The natural gas orifice part numbers in your details are correct. You will need to install those orifices on the burners in this order:

Right Front -- 14K BTU -- part 316237900

Left Front -- 12K BTU -- part 316237901

Left Rear -- 9.5K BTU -- part 316237902

Right Rear -- 9.5K BTU -- 316237902

Center -- 5K BTU -- 316237903

You will need to order 2 of the part 316237902 and 1 of the other orifices.

The pressure regulator will need to be converted back to the natural gas configuration.

A qualified installer should complete this conversion. The instructions for conversion are normally provided with the LP conversion kit and need to be reversed to convert the range back to natural gas. If the installer needs those instructions, let us know and we should be able to get a copy of those instructions from the manufacturer.

You can normally contact your local gas supplier for a qualified installer to convert this range. You may also be able to find a service provider in your area through the

I know how important it is to have the proper amount of flame on a range so that you can cook your food evenly. While yo are waiting for your expert answer, I am adding a link below in where you can enter your appliance model number and a parts list diagram will pop up to help you with your question. I am also adding a link in where you can set up service. I hope my links are useful.
