Product review (3 stars): Test and then test again
The part itself looks exactly like OEM and probably is OEM. It has arrived in a new plastic bag and looked like new and unused. However upon testing I found that it does not work. It did not close when immersed into 20F liquid. Amazon has replaced the part and the new one was OK. I am not sure why this was a problem, but found from other posts that it did happen to others. I am just lucky I did not install defective part without testing
