I'm here. Thanks for your patience. There is no model number "408SWGG00671".....please take another look. That may be the serial number. Also, sometimes an "8" can look like a "B", etc...

I love this site! $9 instead of a repairman or new/used frig can't be beaten. This older woman will worry less now that she knows about this site. Bless you all.
