Refrigeration system preventive maintenance
Performing preventive maintenance will give you peace of mind, increased equipment efficiency and lifespan as well as reduced downtime, less equipment malfunctions and less repairs, resulting in reduced operating costs. Nothing will stop your business like a refrigeration equipment meltdown!
The REFRIGERATION PREVENTIVE MAINTENANCE WORKSHEET will help you complete routine refrigeration maintenance.
Refrigeration Preventive Maintenance SCHEDULE:
Clean your equipment and kill the germs
- Refrigeration units: Every few months, clean condenser coils by using a stiff bristle brush and vacuum cleaner to remove dust and grime. To prevent sludge buildup, regularly empty and clean the drain pans and tubs.
- Fryers: Boil out the fryer twice a week.
- Ovens and ranges: Wipe down rack, walls and the door as part of your weekly cleaning routine.
- Burners, flat-tops and cooktops: Scrub down these parts and surfaces using a disinfectant spray or warm soapy water.
- Grills: Brush ash and grime off your grates after use. Soak grates in warm soapy water to break up grease. Also, empty out any drip trays or areas underneath your burner or grates.
AND DEFROST ON SCHEDULE
Check your temperature and defrost frequency settings daily. If the temperature is set lower than necessary your system will be overloaded, which will shorten its life. If the unit is frozen ice will form, especially on liquids. If your temperature is not cool enough, your food will spoil. Ensure you follow the manufacturer’s recommendations for defrosting. Defrosting your unit too frequently creates unnecessary workload for your refrigerator.
DO NOT OVERCROWD
Air must be able to freely circulate in a refrigerator; over-packing will make the freezer/refrigerator work harder to maintain its set temperature.
BY CLEARING THE AREA
Allow exterior airflow. It’s essential that you clear the air intake and exhaust vents. If you do not, your unit will work harder to cool the food stored inside. This not only consumes more electricity, it shortens the lifespan of your system.
CHECK FOR LEAKS
AND INSPECT SEALS MONTHLY
When the gaskets or seals on your doors are ripped or loose, air will leak. Minor gasket leaks can be repaired with silicone caulk. Additionally, make sure your unit’s door hinges and latches are tightly secured.
Coil cleaning is crucial to the effective operation of your system. Once a month you should inspect and clean your unit’s condenser and evaporator coils. If your coils are covered in dirt and grime, it will affect the transfer of heat from your system.
CLEAN FAN BLADES
Fan blade cleaning is a task for the professionals, don’t do it your-self. Filthy blades will force the fan motors to work harder to rotate the blades. When cleaning the blades, make sure screws are tightened.
Tasks that require professional expertise:
These jobs are normally completed twice annually: Disassemble and clean icemakers; unsanitary icemakers are a leading health inspection violation. Check refrigerant levels. Observe motor operation. Examine all parts for wear and tear before a minor problem becomes a big problem. Check suction line insulation. Clean drain lines. Inspect compressor operation; compressor failure can prompt the replacement of the refrigeration unit, which makes compressor operation checks a high priority on the refrigeration preventive maintenance checklist. Check electrical connections. Test thermometers and recalibrate if necessary.
