The Food Safe Temperature for Refrigeration Systems

Cleaning & Maintenance of Commercial Coolers & Freezers

Your coolers and freezers are essentials pieces of equipment in your foodservice operation. Proper cleaning and maintenance will not only help protect proper operation for food safety and quality, it also helps maintain energy efficiency.

Cleaning Recommendations

Cleaning recommendations may vary by unit – always follow OEM specific recommendations for cleaning and maintenance.


The thermostat must be turned to OFF and the unit disconnected from the power source whenever performing service, maintenance functions or cleaning the refrigerated area.

All personnel involved in cleaning kitchen equipment are required to wear the following safety equipment: chemical splash goggles, impervious gloves.

Monthly or Quarterly Recommendations

  1. Clean light dust and debris on the condenser coil with a simple brush. Heavier dust buildup may require a vacuum or use of compressed  air to blow through the condenser coil. If extremely dirty,place a service call for proper cleaning.
  2. Use warm, soapy water to clean gaskets. Avoid full strength cleaning products as they can cause gaskets to become brittle,
    preventing proper seal. NEVER use sharp tools or knives to scrape or clean the gasket which could tear the gasket and rip the bellows.
Tips & Troubleshooting

Unit not operating properly?

  • Make sure the breaker is turned to the ON position. If tripped, please place a service call to determine why.
  • Make sure the unit is plugged in — it should NOT be plugged into a GFI receptacle.


COOLER | Issues with temperature

  • Is the unit too close to the wall preventing proper air circulation?
  • Is there wear or tears in the door seals/gaskets?
  • Use a digital thermometer to verify if the built-in temperature gauge is providing an accurate reading.
  • Is there dust or grease buildup on the condenser coil?

FREEZER | Unit freezes up

  • Is the fan rotating freely?
  • Is there ice buildup on the fan? If so, melt it to see if that
    resolves the issue.
  • Is there wear or tears in the door seals/gaskets?

Maintenance Tips

Condenser Coils

Failure to maintain a clean condenser coil can initially cause high temperatures and excessive run times. Continuous operation with dirty or clogged condenser coils can result in compressor failures.


Gaskets require regular cleaning to prevent mold and mildew buildup and to maintain gasket elasticity.

Energy Savings

Air conditioning helps promote dry air which cools more easily than moist air, allowing temperatures to drop 3–5°F. As a result, compressors and fans could run 2-3 hours less per day resulting in energy savings of 15–22%.
