In December of 23 I purchased a new Whirlpool refrigerator from Costco. Not long after receiving it, I noticed that it was freezing everything on the first three shelves in the refrigerator. Instead of keeping the temperature at the recommended 37 °. I have had to turn it up to 40°. Then I noticed ice growing up the back wall of the freezer and realized I definitely had a problem with this refrigerator. Even though I have a 2-year warranty from Costco, I was told I had to go through Whirlpool. Whirlpool has the worst service I've ever received. I've had three different technicians out here and each one has been worse than the one before. They seem to pick the lowest bidder to do their warranty work. The last technician that was here did nothing but scrape the ice off the wall and tell me that these things just happen. I have gone through all the higher-ups at Costco and still have not been offered the chance to exchange this refrigerator. Each person passes it on to another person and no one gets anything done. I am now dealing with the managers in my local Warehouse and hoping that they can help me. I would not recommend buying a major appliance from Costco because they don't stand by their warranty. If they did, my refrigerator would have been replaced months ago. Let this be a warning to anyone who wants to buy a major appliance at Costco!
