J Phillips for Model Number JGP945BEK2BB I am converting my GE Profile cooktop from LP to NG, and the installer didn't leave the original orifices. GE is insisting I buy tubes and orifices ($207 vs. $50).,and insisted that something bad could happen (i.e., an gas leak or explosion) if I don't replace the tubes too, is this true? They have two types of replacement orifices: WB28T10116 (simmer, your #AP3949506) and WB28T10115 (main spud, your #AP3885810). The manual says the LP orifices have engraved marks (and they do), do the NG orifices have marks? Do the marks matter? Do I order 4 main and 1 simmer orifice? My burners are RF 18,000btu, RR 5,000btu, LF 9,500btu, and LR 11,000btu.
Answer J. Phillips, It would be necessary to replace the tubes as the GE does not offer all of the orifice spuds as a separate part. The parts that would need to be ordered are the following, For the right front burner you will need 2 orifice the main WB28T10115 and the simmer WB28T10116. For the left front burner you will need WB28T10227, left rear burner WB28T10110 and the right rear burner WB28T10149 Read More... Answered by AppliancePartsPros.com | Thursday, July 30, 2015
