The LP Orifice Kit is an OEM part for Whirlpool gas ranges. It contains a set of five orifices designed specifically for use with liquid propane (LP) gas. Note: For the oven orifices, on some models they are adjustable and some they are not. Refer to parts list for your model when oven orifices are needed. LP orifice kit includes 5 orifices.

Causes of a bad LP Orifice Kit may stem from incorrect orifice size for the specific LP gas supply, wear or damage to the orifices over time, or improper installation.

Symptoms of needing to replace the LP Orifice Kit can include:

  • Uneven heating or incomplete combustion of the burners
  • Yellow or flickering flames instead of a steady blue flame
  • Reduced cooking performance or inefficient heating

This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and some Kenmore models.

Questions & Answers

For Whirlpool Lp Orifice Kit (5) (Part Number: OEM18048639)

Christian for Model Number GFG461LVS1

Hoping someone can help with a confusing range conversion to LP. I bought a used Whirlpool GFG461LVS1 Gas Range for the cottage that was originally NG. I have been trying to convert to LP and have had problems determining what parts are needed for the Bake and Broiler. I have had two gas pros come - one is a tech and the other was a friend who is a gas fitter. Both have not been able to solve the problem. After speaking to the customer service rep at Whirlpool and confirming the part, I ordered the replacement parts W10859321, which included a bake "56" green orifice and broil "100" silver orifice. Link below, although part was ordered through Whirlpool. http://www.appliancepartspros.com/whirlpool-orifice-w10859321-ap5989906.html The main problem is the Bake orifice is male-threaded while the part that was taken out, a gold labelled "49-56" was female threaded. Therefore the bake orifice doesn't fit on the nub. The Broiler orifice ("100") seems to fit the broiler nub but smelled of gas when lit up and therefore has not been used. Does anyone have any suggestions on who can clarify this? Thanks in advance!

Christian, For this model you would simply need to tighten down the original orifices down to snug and open the air shutters on this unit. You do not need to change the orifices.

R. Rodriguez, To convert this unit back to Natural gas you will need to loosen the orifice for the bake and broil burner approximately 1 1/2 to 2 turns and the air shutter needs to be about 3/4 of the way open. You will also need to flip the cap on the regulator from LP to Nat. You will need to get the top burner orifices for the right rear WPW10170506, center WPW10170507, left rear WPW10170508, right front WPW10170510 and left front W10853607.

Mojo, To convert the unit back to natural gas you will need to adjust the oven orifices by loosing then approximately 1 1/2 to 2 turns and closing the air shutters off to about 1/4 way open. On the regulator you will need to flip the cap from LP to NAT. On the main top you will need 2 of the small burner orifices WP9753928 and 2 large WP9753929.

Hello Kay. You will need to replace the gas valve for that burner if the flame does not adjust properly.
