Product review (1 stars): Instant Garbage
"Genuine Replacement Part" received had no part / serial number stamp, and no manufacturer identifier.  Both were shown on image hosted by Amazon, and would be found on a genuine factory replacement part.  No clue if this will open at the appropriate temperature, so discarded, as I don't want to risk a dryer fire.

Purchased a genuine part directly from Sears for a few bucks more, for peace of mind.
