The tube that goes from the stem to the front burner on the stove top is called the front or rear orifice?
Answer Hello John,
The tube that goes from the stem to the front burner is called the front orifice holder.
Is this part hard to assemble?
Answer Hello Mike. No, once the top of the unit is raised, you can access and replace the orifice holder WB28K10189. They are not hard to replace. Be sure and check for leaks after you install the orifice holder. Hope this helps.
