Regular Maintenance Tips for Your Walk-In Cooler

Any piece of commercial equipment is an expensive investment for a business, and when an item such as a walk-in cooler stops working it can be extremely costly. Regularly checking on your walk-in cooler components and performing regular maintenance can help ensure that your walk-in unit runs efficiently and significantly lessen the risk of component failure and downtime.

Here are some regular checkups and maintenance you can do:

1) Clear the Drain Lines

At least once a year, you should confirm that the drain lines from your walk-in are free of any clogs. If you notice any buildup in the lines, you should contact a technician to clear them out.

2) Clean the Condenser & Evaporator Coils

The condenser coil and evaporator coil are two of the most crucial components of your walk-in cooler. They are susceptible to dirt and dust buildup - especially so with outdoor units - and it is important to complete regular maintenance and cleaning at least twice a year to ensure healthy operation.

3) Clean Door Gaskets

Your walk-in unit door is another important part of the unit, and the door gaskets take a constant beating every time the door closes. The gaskets are susceptible to mold and bacteria buildup, so be sure to clean them regularly with soap and water. Inspect the door gaskets for any signs of cracks or tears, and if they are damaged or seem to be stiff or hard you should have the gasket replaced.

4) Check Door Sweeps

If your walk-in unit has a swinging door, you should check the door sweep when you check the door gaskets. The door sweep is at the bottom of the door and is responsible for helping maintain a tight air seal to keep the cool air in the unit. If your door sweep has any signs of tearing or damage, it may not be creating a proper seal and should be replaced.

5) Check Fan Motors

The fans for your walk-in unit are responsible for pushing hot air out of the unit, so be sure to confirm they are running efficiently. Just like the condenser and evaporator coils, the fan motors often collect dust and dirt on the fan blades creating drag and forcing the motors to work overtime. Regular maintenance and cleaning will extend the life of the fan motors and help prevent them from burning out.

6) Clear the Top of the Cooler

A walk-in cooler can take up a sizable amount of space, but it is very important to understand that the roof of a walk-in unit is not a suitable storage space. You should never store items on top of the units. The roof panels are made of insulation and sheet metal and are meant to be insulating elements, not to hold heavy weight. If you have an outdoor unit, you should regularly check for buildup of leaves and other debris that could accumulate on the roof of the unit and clear it off.

7) Lubricate Door Hinges

As mentioned before, the door to your walk-in is one of the most important elements in maintaining the internal temperature of your cooler. The door hinges help keep that airtight seal as well, and it is important to make sure the door hinges stay lubricated. More modern door hinges often come with a self-lubricating component that does not require you to lubricate the hinges, so be sure to determine the type of hinges that are on your door.

8) Check Electrical Connections

Loose electrical connections can cause your walk-in cooler to run poorly resulting in wear and tear on the components, higher electricity bills, and increased risk of a fire.  You should have an electrician check your connections annually and complete any necessary repairs.

9)  Monthly Check

Perform monthly checks inside your walk-in for outside light that is visible around the door, the refrigeration systems, the electrical connections, and between the panels. If you do see light, contact your service technician to correct this issue as you are gaining heat through areas that let light in.  This is making your refrigeration system work harder, costing you more money!

If you follow these simple steps, you can greatly increase the efficiency and longevity of your walk-in cooler.
