LG Range

,

I have a LG Model # lre3023st Range. Replaced RF element with NO success. Sometimes the element will work for a while then sounds like a breaker sound in rear panel and then element will go out, but won’t come back on. Can shut burner off for a while and then it will eventually come back on to shut off again. Everything else works fine. Can somebody give me a part # of what I might need to fix this? Thanks for any help, John.
