8 Top Tips for Expert Fridge Maintenance

The Essential Guide to Fridge Maintenance: Keeping Your Cooling Unit in Top Shape

A well-functioning refrigerator is a vital component of our client’s shops and stores, ensuring the preservation of food and drinks, especially in the warm summer months. Regular maintenance is crucial to extend the lifespan of your fridge, prevent breakdowns that effect sales opportunities, and maintain optimal performance. At Barden FM we know how important it is to help your facility avoid costly repairs and ensure the longevity of your cooling units, so here are our expert’s top tips: 


    Regular cleaning of your fridge is essential for maintaining hygiene and preventing the build-up of dirt, mould, and unpleasant odours. Start by unplugging the fridge and removing all the contents. Use a mild detergent or a mixture of water and vinegar to clean the interior surfaces, including shelves, drawers, and door seals. Wipe the exterior with a damp cloth and be sure to clean the condenser coils located at the back or underneath the unit. Clean coils promote better airflow and prevent overheating.

  • Tip 2: Check and Replace Seals:

    Damaged or worn-out door seals can lead to air leakage, compromising the fridge’s efficiency and causing it to work harder. Periodically inspect the door gaskets for cracks, tears, or signs of wear. If you notice any issues, promptly replace the seals to maintain an airtight environment inside the fridge.

  • Tip 3: Ensure curtains are in good condition

    Curtains for walk-in fridges help insulate the temperature within the unit . This especially important when the doors are open during restock and in other times of heavy use. Ensure curtains are are in good condition with no gaps or missing parts. We provide a full refit and replacement service to ensure our client’s walk-ins are kept at optimal effeciency.  


    Regular defrosting is essential to prevent ice buildup, which can hamper the fridge’s cooling efficiency. Defrost the freezer compartment as needed or if ice reaches a thickness of around 1/4 inch. To the right is a photo taken by one of our engineers at one of our client’s refrigeration units that was running at a higher temperature than required. The ice build-up on top of the evaporator coil was seriously hindering its ability to function effectively. This issue would be avoided with regular defrosting. 


    Use a thermometer to check the internal temperature periodically, ensuring it remains within the optimal range. Adjust the temperature settings accordingly if needed, as can be found on the outside of the cooling unit. Allow sufficient time for units to cool down to the correct temperature after every adjustment. 

  • Tip 6: Avoid overloading the fridge

    Overloading the fridge not only inhibits proper airflow but also puts strain on the compressor and other components, potentially leading to breakdowns. Be mindful of the fridge’s capacity and avoid storing excessive items beyond its recommended limit. Avoid blocking fans and other key components with excess stock. Arrange food items properly, ensuring there is enough space between them for cold air to circulate.

  • Tip 7: Regularly Check the Condenser Fan:

     The condenser fan plays a vital role in rejecting heat and cooling the fridge’s compressor ensuring optimal performance. Dust and debris can accumulate on the fan blades and grilles, hindering its efficiency. Where accessible, check the condenser fan regularly and clean it if necessary, using a soft brush or a vacuum cleaner. Ensure the fan spins freely and without any obstructions.

  • Tip 8: Schedule Professional Maintenance

    While regular cleaning and inspections can go a long way in preserving your fridge’s health, we advise scheduling professional maintenance and deep cleaning at least once a year with our qualified fridge technicians. We perform a thorough inspection including pressure testing, address any underlying issues, and provide preventive maintenance services to keep your cooling unit in top shape.
