Saturday night at 6:30, the power flickers and our refrigerator control panel throws an error code. We unplugged and plugged the refrigerator back in to see if it would reset...no such luck. Called Kingdom Appliance at 6:30 on a Saturday night. They answered the phone and walked us through a reset process and it worked! Completely saved us and our food completely free of charge! I will never go to anyone else for appliance repair!
