Your text indicated you are looking for the part "Cole Hersee CR400112 NN". I simply entered the part number "CR400112 NN" into the search argument field in Amazon, and it's there on Amazon's first page for under $8 Prime delivery.
Later this same day...
I tried again to find the part on Amazon and it wouldn't show it to me. I entered "Cole Hersee CR400112 NN" into a GOOGLE search and it found the part but with the leading two characters being "RC", not "CR". I don't know if you transposed the "CR" to "RC" or if these are indeed two different relays. So... I'm now as confused as you are. lol
