How to maintain commercial refrigerators

If you’ve invested in a high-quality commercial fridge, you want to know that it will give you plenty of useful service in order to maximise the return on your investment. You can prolong its lifespan by maintaining a regular cleaning and servicing regime.

The most important aspect of maintaining a commercial refrigeration unit is to keep it clean. This is also a very simple way of keeping it in good working order by spending time once a fortnight or once a month carrying out a very thorough wash and clean.

Use detergent or a mild soap to clean the interior. You will find specialist cleaning products that you may choose to use. This should be done at least once every month, and you must remove everything removable inside and thoroughly wash it down, including the drawers, shelves and boxes.

Clean the exterior using a safe cleansing product, especially if you have a stainless steel unit. You can see examples at

The compressor

Clean the compressor, but make sure you unplug the fridge first. This part of the fridge should be dusted and wiped regularly to remove dust and dirt that would otherwise build up and prevent full operation. By keeping the compressor free of debris, you can also help the unit to run efficiently, which saves you money on your energy bills and reduces your carbon footprint.

Move on to the motor and fan. Again, the unit absolutely must be unplugged or it can be dangerous. Use a soft cloth to remove any buildup that could prevent the fan from fully spinning or that could jam the unit. This will help the fridge to operate at the correct temperature and avoid frost build-up. Remember that if the fan is forced to work harder than it is meant to, the lifespan of the refrigerator will be shortened.

Regular checks

Alongside your cleaning programme, carry out regular checks of the fridge to make sure it is running at the right temperature. Check that everyone who uses it is fully shutting and opening the doors. If doors are left slightly ajar, frost will build up, energy will be lost and the interior temperature of the fridge will be compromised. Finally, invest in an annual service to check for any emerging issues that can be remedied.
