On a positive note, I did get the following email back this morning from their customer service: "We do get defective parts every so often, sorry about that. We could have just reshipped a new one for you. I will let the parts manager be aware of the problem that you had. Thank you Mindy"

But I did not need a replacement as I was able to fix it using the old part. I just wanted to let them know about the issue.

I am sure they get the same part as all the other venders so be careful when handling the heater switches.
