Thanks so much. I'll start with the ohm meter at the element, as per co.aulakh, and if that isn't it, then I will follow Michael's advice. I do so hate dissasembling this stuff in cold Michigan weather. I'll update the forum when I get through.
In the meanttime, if there is any more advice or encouragement, send it my way, please.
