We got a used stove, but the seller had lost one of the burner caps. Talked to a couple appliance stores and they said these things were difficult to get and very expensive and would have to be ordered. So we looked online, and stumbled on appliancepartspros.com! It took a while to find the right part mostly because we weren't sure exactly what it was called. We had a couple options and bought one of each because we figured at least one would fit, and they were very reasonably priced! So the three legged one did fit. It just pops right on, no tools needed. And the other two will fit on other burners if we ever destroy one!
