Michael S Bluffton , SC April 03, 2021 Refrigerator not cooling freezer icing up. Spoke with one of your techs who walked me through the issues with my Whirlpool refrigerator. She correctly determined it was a faulty control board. Sent me one, I installed it and the refrigerator is now working perfectly. Great service! 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
