Complete Refrigerator Maintenance Schedule Guide

Luxury refrigerators are designed to last 20 years or more with proper maintenance. Following a regular maintenance schedule protects your investment and ensures optimal food preservation.

Monthly: Clean the exterior and handles using appropriate cleaners for your finish. Stainless steel requires different care than integrated panel units.

Monthly: Check door seals for debris and wipe clean. Sticky seals don't close properly and waste energy.

Every 2-3 months: Clean condenser coils, more frequently in Arizona's dusty environment. Dirty coils make the compressor work harder and reduce cooling efficiency.

Every 3-6 months: Replace water filters according to manufacturer recommendations. Overdue filters can harbor bacteria and reduce water flow to ice makers.

Every 6 months: Check and clean the drain pan beneath the unit. This pan can collect dust and debris that promotes mold growth.

Every 6 months: Inspect door gaskets for wear, cracks, or gaps. Early replacement prevents energy waste and temperature problems.

Annually: Clean the interior thoroughly, removing all shelves and drawers for complete access.

Annually: Check the temperature accuracy using an independent thermometer. Adjust calibration if needed.

Every 2-3 years: Consider professional maintenance for inspection of refrigerant levels, compressor performance, and overall system health.

For Sub-Zero and similar premium brands, following this schedule can mean the difference between a 15-year and 25-year lifespan for your refrigerator.
