No reason to feel stupid...
Asking questions is part of learning. We have all been there.
It would only pop open when it needs to crush ice or something eh?
Yes, if it's the common whirlpool type I was thinking of.
As for getting the model number. If you don't have a pen and paper handy, but have a cell phone camera you can snap a photo of the model/serial number tag for later reference too. I have done that a few times, lol..
Feel free to ask all the questions you want. Our forum is kind of like a class room. If one person ask a question in a class room you know someone else in class was wondering the same thing.
In our forum if someone post a question there could be hundreds of people or even thousands of people over time that are searching for the answer to that very same question you asked.
I may not always have a answer for you, but there is enough of us around that someone should be able to point you in the right direction.
Just don't' forget to return the favor if you ever get the chance to lend a helping hand to another forum member looking for answers.
