Walk-in door gaskets typically last 2-4 years and should be inspected every 6 months. Signs of failing gaskets: visible tears or cracks, frost buildup near the door frame, condensation on the door frame, noticeably warmer temperatures near the door, or the door not staying closed. A failing gasket forces the compressor to work harder, increasing energy costs and reducing equipment life.

Signs of compressor problems: unit not reaching temperature despite running constantly, compressor making loud knocking or grinding sounds, compressor starting and stopping rapidly (short cycling), compressor not starting at all, or high pressure shutdowns. Compressor failure is typically the most expensive refrigeration repair. Early diagnosis can sometimes allow for less costly repairs — don't wait if you hear unusual compressor noises.

Commercial refrigerators must maintain 40°F (4°C) or below for food safety compliance. Walk-in freezers should be at 0°F (-18°C) or below. Many food safety programs require refrigerators to run at 35-38°F for proper margin. If your unit struggles to maintain proper temperature, especially during busy service periods or in hot kitchen environments, call a technician — compressor capacity or refrigerant levels may be the issue.
