Walk-in freezers make a wonderful addition to any commercial kitchen or warehouse. They make storing large quantities of perishable goods possible, which means that, as a business owner, you can maximize the return on your investments.
But what happens if your walk-in freezer isn’t cooling properly or fails to defrost? Of course, you don’t want to lose the stock you’re storing in your appliance. But, when your walk-in freezer fails to maintain the correct temperature, you can easily lose hundreds or thousands of dollars worth of food.
To avoid this, the best thing to do is to learn everything you can about the most common walk-in freezer issues, and how to resolve minor issues, before they turn into serious problems.
Evaporator Fan Not Working
Walk-in freezers use evaporator fans to move cool air around the appliance. A walk-in freezer evaporator fan will probably run almost constantly to keep air cool and moving throughout the unit.
However, it’s because of this continued use that it’s common for an evaporator fan to malfunction over time.
If the evaporator fan isn’t working, your walk-in freezer won’t be able to maintain cool temperatures, which isn’t an ideal situation.
One way you can tell your evaporator fan isn’t working well is to test the temperature in different areas of your walk-in freezer. If the temperature is cooler near the door or on one side of the walk-in freezer, the evaporator fan isn’t moving cool air effectively (if at all).
Regular maintenance is key to ensure the evaporator fan works as it should. However, when your evaporator fan breaks down, it’s best to contact a knowledgeable appliance professional to help you replace the broken part.
Evaporator Coils And Frost Build-Up
The evaporator coils are usually located at the back of your walk-in unit. This circulates a coolant, known as freon, throughout the unit to help disperse heat away from the unit. When these coils get covered in dirt, dust, and other types of debris, they’ll daily to properly release heat, which will cause your unit to work double-time just to keep up.
Alternately, you might be experiencing ice building up either inside or outside your unit.
In some cases, humid air can get into your walk-in freezer, causing excess condensation which freezes and turn to ice.
Leaving the door open, for example, is one way for humid air to get into your appliance.
Or, you might also have an issue with your walk-in freezer door hinges and gasket, which can prevent the door from creating a proper seal, in turn, allowing humid air to seep into the appliance.
Walk-In Freezer Is Not Cooling Properly
If your walk-in freezer isn’t cooling properly, you could have a problem with the freezer thermostat. The freezer thermostat is the device that allows you to set how cold you want the appliance.
Essentially, it regulates the unit’s internal temperature.
If your unit’s thermostat has become faulty, this might be why your walk-in freezer isn’t reaching the right temperatures.
Also, check to make sure that the appliance doors lock securely, that there isn’t any damage to the hinges, and that the door seals are in good working order.
For other issues, or if you have questions about freezer repair, don’t hesitate to talk to a professional technician for help.
They can properly examine your walk-in freezer and diagnose any potentially malfunctioning parts. They can also replace and repair broken parts so that you can continue to use your walk-in freezer.
Walk-In Freezer Fails to Defrost
Walk-in freezers typically run a defrost cycle 1-2 times a day. A defrost cycle is so important because it helps to remove ice build-up generated from humid air.
Too much ice build-up can prevent your walk-in freezer from running properly. Also, ice build-up can permanently damage different parts of your walk-in freezer if it’s allowed to build up for too long without being removed.
Making sure your walk-in freezer’s defrost cycle works well is one way to increase the lifespan of your appliance.
One way to diagnose whether or not your walk-in freezer fails to defrost is to simply look for ice build-up.
If you see ice build-up on the evaporator coils, on the inside or outside of the unit itself, or any excessive condensation, an appliance repair technician will need to check your defrost heater and timer, the thermostat, and the unit’s main control board.
The defrost heater, thermostat, and control board all work together to trigger a defrost cycle. If one or more of these parts aren’t working properly, your walk-in freezer won’t defrost and you’ll run into issues.
To troubleshoot the issue, contact your local appliance repair technician. They’ll be able to discuss your issue and provide you the advice you need to get your walk-in freezer back in working order.
