GE Profile Gas Cooktop JGP636AEV2AA

Model Number: JGP636AEV2AA
Main Symptom: Need conversion kit or individual orifices

GE model number: JGP636AEV2AA I’m converting from natural gas to LP & need the individual LP burner orifice part numbers because the conversion kit is discontinued. Can anyone help?

The manufacturer has discontinued the OEM LP orifices for this model and are no longer available for purchase.
