Bill's Appliance Repair

1) Check if the condenser unit is running. 2) Inspect condenser coils for dirt and debris — blocked coils are a common cause. 3) Ensure walk-in door gaskets are sealing properly. 4) Check if evaporator fan is running. 5) Look for ice buildup on evaporator coils (defrost system failure). If temperature is rising significantly, move temperature-sensitive inventory and call a technician immediately — this is an emergency situation.

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.

High-temperature commercial dishwashers must reach 180°F (82°C) at the final rinse to achieve proper sanitization per NSF and health department standards. Low-temperature chemical sanitizing machines must maintain proper chemical concentrations (chlorine, iodine, or quaternary). If your high-temp machine isn't reaching 180°F, it's not properly sanitizing and may fail health inspection. Call a technician immediately.
