Minimize door openings if the temperature of the Jenn-Air refrigerator is too warm or you see moisture. Allow a few hours for the refrigerator to return to normal temperature when adding a large load of food. Try resetting the refrigerator--turn the fridge off, and then on again with the digital controls.
Place food in airtight, moisture proof packaging when storing food because smells can permeate the ice. Off-tasting ice problems can also be reduced by washing the ice bin from time to time. Discard the ice in the bin and wash the bin itself with warm, soapy water. Rinse it thoroughly. Replace the water filter if there is one.
Vibration and noise can be reduced by ensuring the refrigerator is level. Newer refrigerators do make noise, though a lot less than older models. Buzzing, pulsating, sizzling and gurgling sounds are all normal. Buzzing is related to the ice maker; pulsating is related to the fan and compressor; and sizzling and gurgling is water dripping on the heater during defrost cycles.
Keep the doors closed if the motor runs too much. Newer refrigerators run more than older ones. This is due to high-efficiency compressor and fan activity.
