Verify if the outlet has power by plugging in another appliance.Not Cooling/Freezing Properly: Ensure the mechanical thermostat dial on the lower right is set to the correct cooling level. Keep the appliance away from direct heat sources and check that the lid is sealing completely shut.Excessive Frost Build-up: This unit uses a manual defrost system.
