Product review (2 stars): (Probably) Not OEM
As others said, despite description stating OEM sealed part I received generic parts in a ziplock bag with a generic printed sticker label. I guess I'll install and see how it goes, but parts almost definitely are not OEM. I can't imagine kenmore parts don't get stamped with their part number....
I may update if they don't seem up to par.

FYI if you feel your dryer is clean, exhaust is clear, and overheat is truly a sensor error, you can often slam the flat side of the sensor down on a hard surface and it will reset, although they tend to be overly sensitive and prone to triggering again. It usually will at least work till you receive the replacement.
