Bob, I replaced mine with a 6.95 Lowe's special. There's absolutely no magic in them, a simple thermo spring switch. Replace it for peace of mind,
the originals will sometimes close but not conduct electricity due to crud on the contacts over the years. Ask me how I know this and dam' near froze
one night last year.
