I'm not sure which number it is. Inside the dryer door there is a sticker...it says
SER MS 321126
Well, unfortunately, that's a bit of a problem for me. My husband is a football coach and is at practice right now. I don't know where he keeps his tools. Even if I did know, I have no idea what/where the filter is. I guess I will suggest he do that when he gets home.
I'm sorry! Thank you very much for you help though. I'm assuming the money already went through.
