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.

Critical food safety temperatures: Cold holding — 40°F (4°C) or below for refrigeration; freezer 0°F (-18°C) or below. Hot holding — 140°F (60°C) or above for steam tables and food warmers. Cooking temperatures vary by food type (145°F-165°F). Dishwasher final rinse — 180°F (82°C) for high-temp machines. Any equipment consistently failing to maintain these temperatures is both a safety risk and a health code violation.
