Some places sell matching sets of appliances but I'm not sold on that idea. I think they group together what they can sell of one brand at a reasonable price but not necessarily the best quality. My neighbor next door bought one of those sets that had the refrigerator, range, dishwasher, and microwave and his microwave quit after less than two years and I think he said they had an issue with the refrigerator already. I don't feel like everything has to be the same brand to match. Our double oven range is Samsung, the dishwasher is LG, and the refrigerator is Whirlpool and they match just fine. Of course the white microwave doesn't match but I don't feel like it's necessary to replace it unless it isn't working and it works great.
