As it turned out I did not need the cap as the residue burned itself off at the next use of the burner. However, I had excellent service from appliance parts pros and the young lady who took my order was wonderful. The burner cap was here in a couple of days. I put it on the stove kept the extra one just in case, and all is good. I also bought some stove top cleaner which I will use as glass shower door cleaner.
