How to Maintain Your Walk-In Cooler

walk-in cooler

Like any other type of equipment or appliances, walk-ins should be regularly maintained and cleaned, in this blog we’ll outline how to properly maintain your walk-in cooler. Restaurants, hotels, and other establishments use a walk-in cooler to store food supplies needed to serve customers. The walk-in cooler and freezer can store large amounts of items from meat, vegetables, fruits, and other cooking necessities to keep them at temperature and avoid spoilage or food safety issues. A small spill can effect the items stored in it. Here are the parts of a walk-in cooler that you should be regularly cleaned and sanitized to keep food safe and the equipment running efficiently. 

For shelving

Make sure to clean the shelving where you store your food supplies to avoid the development and growth of mildew, bacteria, and other harmful elements.

You can clean and sanitize using a clean cloth with a mild solution of water and bleach. Make sure to wipe it again with clean water to remove harmful chemicals that may contaminate your food supplies.

For condensing unit

The condensing unit is the critical component of your walk-in cooler as this contains the compressor, condensing coil, and condensing fan motor. 

Make sure to shut off the condensing unit first before you start cleaning it. There are cleaners that you can buy from supply houses to spray on the coils to clean them.

For cooler door seals

The seals around walk-in cooler and freezer doors should be pliable and have a tight connection. Otherwise, you would waste a lot of energy, and your condensing unit may be damaged for excess use.

If you notice that it is starting to tear or become brittle, consider replacing the walk-in door seals. Your walk-in will experience wear and tear so make sure to conduct regular inspection and maintenance.

For evaporator fan

Your evaporator fan collects and drains the water, that is why you should clean and sanitize it at least once a year to avoid dust and dirt from clogging it. We recommend having this work done by a technician.

For temperature controls

Some people tend to adjust the cooler’s temperature control during holidays and other peak seasons to compensate for high use, but doing this will only lead your cooler to freeze-up once the unit stabilizes, damaging the walk-in cooler.

When you notice or hear changes in the normal operating noise, that may be a sign that your unit is damaged, and you would need a technician to fix it. 


A walk-in cooler is a valuable piece of equipment and it should have a regular cleaning and maintenance to keep it in excellent condition. When cleaning, you should include the shelving, condensing unit, door seals, and evaporator fan. Also, avoid adjusting its temperature unnecessarily as this can damage the unit.
