SIEBE Thermostatic Switch part # 275-3392-00. I have a partial case of these so you are buying one or more from that case depending on your needs. Each is new old stock. May have a calibration mark.

IMPORTANT NOTE:Please check the pictures. Because there are many similar looking parts,  please compare the number and specifics with  your part you are replacing. This will help prevent "Part doesn't fit" or "wrong part" issues, saving you time and money. Again, I do not know what these fit so it is important to match model numbers.

New lower price for the time being...Please check the pictures and email any questions. If there are any problems please message me first. I will try to help.

 Thanks for checking my other listings. Thanks. John WP4DMV.
