[SSN596]

Thank you very much. The complete model number is MGR5770ADW . I thought the letters were not important, so I omitted from post. In searching for parts, it seems that the burner part differs depending on whether it is a "series 10" or "series 13" . My serial number starts with 13 so I assume that is the series?

It is not a glass top; just a sealed recessed metal top with heavy iron grates over the burners.

From the looks of the tool...sort of a strap wrench or oil filter wrench.... does the burner just unscrew? What about the electric connection to that igniter electrode?

I tried to clean the electrode with some fine emory and some alcohol. Even with the lights out, you cannot see a spark; but if I let it keep clicking, it will light in about 15 seconds, usually.

Thanks for the tip on the manual; I think I will order that because I am a nut for good tech. repair books, even though any more I don't do a lot of these jobs myself. I am usually willing to spring for a repairman, but this seemed like an easy job, so I feel now I am "committed"!
