It is usually quite clear when you require Sub-Zero refrigerator maintenance, but preventative maintenance is always a preferable approach to product failure.
Top Signs You Need Sub-Zero Refrigerator Maintenance
Outside of normal wear, the unit should consistently sound and feel the same. Here is a short list of symptoms to keep an eye out for–it may save you time, money and food.
Sub-Zero Refrigerator compartment:
- Consistently warmer cabinet or food temperatures are a sure indicator that a problem exists.
- Consistent excessive sweating or moisture on the interior of the refrigerator walls, shelves or food containers.
- Premature food spoilage, dairy products that sour before reaching expiration dates, vegetables wilting quickly.
- Liquids or vegetables freezing in the fresh food portion of your Sub-Zero.
- Any quick changes to normal operation in your unit such as new noises, louder noises, a change in how the door opens or closes.
Sub-Zero Freezer compartment:
- Thawing or inability to freeze food in a timely manner is a sure indicator that a problem exists.
- Any signs of water, ice build-up, or frost anywhere in the freezer cabinet or on stored food.
- If the unit has an icemaker and production has stopped.
- Excessive heat coming from the top of the unit or around the mullion surface (the perimeter surface that the door gasket seats against).
- Any quick changes to normal operation in your unit such as new noises, louder noises, a change in how the door opens or closes.
