Ruben T Greenfield , CA December 10, 2016 Appliance: Model PWE23KSDESS Refrigerator wasn't cooling I watched some videos from ApplianceParts Pros and, although the refrigerator wasn't the same model, I got the idea of the fans I needed to replace. They had the parts so this made it very convenient. My refrigerator is now working perfectly. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
