Three Most Common Walk-In Cooler Problems

walk-in cooler problemsWalk-in coolers are one of those appliances where we just expect them to work. They are the cornerstone of business operations for restaurants, cafeterias, and other food-related businesses. When they break down, and they do break down, it can be a little nerve-wracking to diagnose the issue without immediately calling in a professional. Modern Air & Refrigeration of Sarasota would like to equip you with the know-how of how to deal with the three most walk-in cooler problems continuing our drive to educate our followers.

Walk-in Cooler is Freezing

Our first item on the most common walk-in cooler problems list is a common issue that might seem antithetical to coolers. Some business owners experience the unpleasant problem of a walk-in cooler freezing up. The ice is usually concentrated around the evaporator. To remedy the issue, first, melt the ice off the evaporator and make sure the evaporator fan is rotating correctly. The ice issue might also be caused by a dirty coil and drain line. Make sure these areas are clean and clear for proper ventilation preventing ice formation.

Walk-in Cooler Temperature Fluctuations

This is possibly the worst problem in our walk-in cooler problems list. Uneven temperatures can lead to dangerous conditions as sub-cooled food can be dangerous to your customers. There are several causes that can lead a walk-in cooler to fluctuate in temperatures. Check subcooling, superheat, and operating pressure to ensure they are all within regular parameters. These numbers can be found in your operator manual. Most often, the cause might be as simple as the door not sealing correctly due to age or disrepair. The last culprit that might cause uneven temperatures is the compressor. If it turns off before the set temperature is reached then it might be time for a replacement.

Walk-in Cooler Problems: Completely Dead

The most jarring of all walk-in cooler problems is when the unit is completely non-functional. The first thing you want to do is not panic. Check your electric connection and make sure it is connected. The unit is sometimes connected to a disconnect as well, ensure this has power. A completely nonoperational cooler is in most cases either an easy fix via reconnecting power or a tough nut to crack as you might have to call in a professional. Electric issues are best left for those with experience in the deep mechanics of a walk-in cooler.
