to FRF. You'll find quite a bit of helpful information. Got a question just ask. Now as for your questions.
1. Go to the link below and check the filters and cartridges. There are two sizes 5" and 10". Most of these type filters especially the 10" type can be purchased at most home stores like Home Depot or Lowes, even WalMart.
2. The refrigerator recall is listed numerous places on the forum, but it's basically a precaution type fix kit. It took about an hour to do at the dealership.
3. As for finding the replacement glass dish for the microwave did you try to Google Manufacturer and Model#? And there's always eBay.
