Common Problems That Can Arise With A Walk-In Cooler & How To Help Prevent Them

Walk-in coolers are a crucial appliance for commercial facilities that require large-capacity cold storage. Walk-in units offer a convenient, low cost, flexible solution for your business' refrigeration needs as well as providing extra cooling power and space for your facility. While most modern walk-in units come with features that alert to temperature fluctuations, there are still other issues and problems that could arise. Regular scheduled maintenance and cleaning can help prevent a decent amount of problems, however here are some of the most common walk-in coolers problems to keep an eye out for.

EVAPORATOR / CONDENSER COILS - evaporator and condenser coils are prone to issues for several reasons. Not only are the susceptible to dirt and debris build-up, as well as icing of the coils. This occurs due to the defroster cycles that are run to remove frost builds ups on the coils. This excess water typically is drained from the freezer, however if there is excessive water it could lead to clogs and poor draining, in which the water can refreeze and cause problems that push the compressor to have to work overtime and increase the wear and tear on internal walk-in unit components.

EXTERIOR PANEL LEAKS - the actual body of the walk-in freezer is made up of insulated wall panels that are designed to work with in conjunction with the walk-in door to create an air-tight, temperature controlled seal. While there are no mechanical parts to the insulated panels they are still susceptible to damage and repair. Any type of leak or hole can not only cause cold air to escape the unit and allow warm air to seep in, but it can also lead to excessive moisture build up inside of the walk-in unit itself which poses health risks due to bacteria and mold, and also can lead to components freezing over and getting damaged.

CONDENSER BLOCKAGE - every walk-in unit has a condenser that has the job of removing heat away from the walk-in unit itself. In order to effectively do this the condenser needs to be placed in a well ventilated area that is temperature controlled. As time goes on situations can occur that cause the condenser to become obstructed and cause damage. Dust and debris can build up on and around the condenser and cause poor heat transfer, leading the condenser to have to work overtime to do its job. On top of dust and debris there can be physical obstructions, such as storage boxes, that can restrict the flow of air to the condenser. Always make sure that the condenser is clean and clear of physical obstructions that could cause problems.

While these are the most common issues that we see with walk-in coolers and refrigerators, there are many other issues that can arise. Routine maintenance and cleaning can help prevent a good portion of problems, however if you for some reason feel like your cooler is having problems, making funny noises, not keeping temperature properly, etc. you should reach out to a certified refrigeration technician to come out and assess the situation. The longer that an issue continues the more severe potential damage to the walk-in components can be.
