Frank Krieger for Model Number JGP633SET2SS serial # SD708378Q I ordered two new cooktop knobs from GE parts using my model # and when I received them neither one will slide onto the post.I even tried a little wd40 , but no luck. They appear to be the correct part ( WB03T10325) and when I called them about the problem they tell me it should fit because they are the right part. The only difference between the new ones and the ones that came with the cooktop are the #'s on the back of the knob. The primary number on the old and the new match ( 191D5100) but there is a second # as well which is different.On the original knobs that # is KIP5H08 while on the new ones it is KIP5E95. Are there two diiferent knobs for this model, and do you have any with the KIP5H08 on the reverse side?
Answer Frank, No, there are not two different knobs for the model number you supplied, There are only three versions of the cooktop, and they all use the same knobs WB03T10325 / WB03T10325 Knob. The numbers on the indicate (191D5100) the manufacturing/production part number, and the (KIP5E95) number is the production date, machine and "plant" where the part was produced. To the best of our knowledge, these are the "original" knobs and have not been revised,redesigned, etc. and should fit the gas valve stems with little or no issues. You may want to check the "d" shaped retainer ring, and/or the center shaft of the new knobs for distortion or accumulation of the stainless steel coating on the knob. Read More...
