Walk-In Cooler Is Spoiling Food: 8 Common Reasons

Your walk-in is stuffed with food that is your business’s inventory so you have to keep it fresh. But if your walk-in cooler is spoiling the food, then it’s not keeping the food in the right environment it’s supposed to. You must consult commercial refrigerator services. Here are some reasons why your walk-in cooler is spoiling food.

Causes Of Your Walk-In Cooler Spoiling The Food

Incorrect Temperature Settings

We will start with a simple cause. Check the temperature settings of the walk-in. It should be what you have set or what your management has instructed. According to the FDA, the temperature of a walk-in cooler should be below 40°F. However, many experts suggest that the ideal temperature for a walk-in chiller is 35-38°F.

As you already know these settings are for a walk-in cooler for keeping things cool. If you have a walk-in freezer, the right temperature is between 0 to -10°F.

Thermostat Problems

A thermostat showing incorrect temperature is a common issue. This can lead you or the staff to believe that the temperature is fine when in reality the temperature is warmer and that’s why the walk-in cooler may be spoiling the food stored inside.

Therefore, if you suspect that the temperature you’re seeing is not right, double-check it and use a food-grade thermometer. Place it in the central part of the walk-in cooler and in a medium height to get a good reading.

However, keep in mind that all walk-in cooler manufacturers emphasize that the temperature shown by the thermostats can be 2-4 degrees different than the actual temperature.

Poor Food Storage Practices

Bacteria growth on food or food spoilage can be due to a problem with the walk-in cooler, but in some cases, the cause may be poor food storage practices. This is a kind of a problem that you or your staff can investigate themselves so it’s better to get this out of the way so you can then have a walk-in cooler expert check the unit.

Storing A Food Item In The Walk-In Cooler That Isn’t Meant For It

A food item that must be frozen to keep fresh will be of no use if you put it in a walk-in cooler unless you have placed it for thawing. The food will allow bacteria and pathogen growth which will not only spoil that food, but can also spread to the nearby foods as well. So, always check the labels of products so you know which should be frozen and which are fine when refrigerated.

Keeping Raw Meat And Ready-To-Eat Products In The Same Rack

Raw meat and other products like fish are the most prone to spoilage and developing pathogens. Their storage life is also less compared to other products. This is why you must keep them in separate racks. In fact, every product type should be at a certain distance from others and some should be in separate racks if you have the space.

Storing Food Items In The Wrong Racks

As mentioned above, some foods are quickly perishable like meat so keeping them in the right racks is important.

Vegetables and fruits should go to the topmost shelves. That’s because the bacteria on these is less dangerous as compared to that of raw meat. So, even if water or condensation drips from them to the food items in the lower racks, it won’t cause a problem.

Then comes the place for precooked items. The rack under the produce items should be for them. Why? Precooked food already reached a high temperature of 140+° Fahrenheit killing pathogens in it so anything dripping from it is also not dangerous for the items placed beneath it. However, keep in mind that dripping from pre-cooked food is still not preferred because it can alter the taste of the food underneath it.

The rack beneath precooked food should be for dairy items like milk, cheese, and eggs. Dairy products can produce bacteria that can be harmful but as long as they are kept at a temperature of 40°F or lower, there is little to no risk of dairy contaminating the items placed in the racks under it.

The second last rack should be for raw meat. It has a high risk of developing pathogens so its dripping due to condensation is bad for other foods.

In the bottom-most rack, you should place thawing food items as they are bound to drip. Anything you put in the walk-in cooler from the freezer to defrost should go there.

Placing Sensitive Items Too Close To The Door

When the four of a walk-in is opened, warm air enters and affects the nearby items the most. So, if you have raw meat or dairy near the door, its temperature may frequently reach the danger zone (between 40°F to 140°F). Even if the temperature of these products goes to 45°F frequently, they will allow the growth of pathogens that will lead to food spoilage.

Storing Hot Items Before They Cool Down

Every food business follows this practice but sometimes, in the rush, a staff member might put precooked food in a walk-in cooler that is still releasing steam. This can be bad for the items stored in it. Because due to the increased temperature, that part of the walk-in refrigerator may become a good place for the growth of microbes.

Moreover, if this is done frequently, it can cause spoilage of a large food quantity. Plus, it will also affect the energy efficiency of the walk-in cooler as it will use more energy to cool down the hot food.

Therefore, make sure the food is cooled before you store it in the walk-in. Follow the recommendations of the US Department of Agriculture (USDA):

  • If the food is in a large quantity, divide it into smaller portions for faster cooling outside and inside the walk-in cooler. Do the same for large pieces of meat.
  • Clean the sink and put cold water and ice in it. You should then place the container that has the food in the sink. During this, make sure the water in the sink doesn’t get to the food in the container.
  • Remember the two-stage cooling technique. In the first stage, the food should be cooled from 140-70°F within 2 hours. In the second stage, it should take about 4 hours for the food to reach the temperature of 41-40°F. When it’s at 41-40°F, you can safely put it in the walk-in cooler after covering it. Moreover, make sure never to cover the food when it’s hot.
  • Additionally, don’t use the outdoors for cooling the food because there can be temperature fluctuations that can be bad for proper cooling. Moreover, animals can find the food and contaminate it.
  • Use a food-grade thermometer to check the temperature of the food at various intervals.

Walk-In Cooler Problems

Any problem with a walk-in cooler that impacts its cooling ability can cause food spoilage as well. Many times, dirty condenser coils, evaporator coils, fans, or vents can cause malfunctions in walk-ins. So, make sure your walk-in is cleaned and maintained properly.

Moreover, door seal and hinges issues can leave the door unsealed. This allows warm air in, wreaking havoc on the food and increasing utility bills as well.

In addition to that, frost buildup in a walk-in cooler can cause various problems including food spoilage. This can happen due to an issue with the door, gaskets, pressure relief port, insulation, etc.

Conclusion

Food spoilage in walk-ins can be due to food storage errors or an issue with the walk-in cooler itself. So, go through the food storage practices and also have the unit inspected by a walk in cooler repair Alexandria technician.

What Are The Causes Of Ice Buildup In A Walk-In Cooler?

Frost buildup inside a walk-in cooler can directly affect its performance and, if not fixed soon, it can result in damage to the vital components. So, you need a commercial appliances repair expert to inspect your walk-in cooler and determine why it’s freezing up. Here are some causes of ice buildup in walk-in coolers that will help you fix yours.

Causes Of Your Walk-In Cooler Freezing Up

Human Error

A common reason for walk-in coolers freezing up is the door is left open for too long. Why is this a problem? One of the things that triggers ice buildup inside a walk-in cooler is warm, humid air. When humid air enters the walk-in cooler, the refrigerator works harder to cool down the interior. In this attempt, the humid air turns to ice.

So, if the door of the walk-in cooler is open even for only 10 minutes, it will cause ice buildup. However, this does depend on the region where your facility is. If the air in your region is humid, icing will occur with only a few minutes of the door left open.

Usually, staff members follow the rules and keep the door closed and when they open it, they do it for a very short interval. However, during stocking the refrigerator, staff members might forget to keep the door closed or have to keep it open to bring many batches of food items inside the refrigerator.

So, instruct your staff to keep the door closed when stocking the food and bring all the food inside the walk-in cooler at once and then place it on shelves after that.

Moreover, to prevent the staff from leaving the refrigerator door open accidentally, install self-closing hinges or a door closer. Additionally, to keep the door from being open for too long in normal operations other than food stocking, instruct the employees to be sure of the items they need to take from the refrigerator or put inside it so they take less time when opening the refrigerator and performing the task.

Damaged Gasket

A walk-in cooler has gaskets in different places to keep two separate parts sealed. For example, the door has a gasket installed all over its ends so that when the door is closed, the gasket ensures that warm air doesn’t go inside or cold air doesn’t escape from the refrigerator.

Over time, these gaskets become loose, worn, or damaged. Due to this, even when the door is closed, the worn gasket doesn’t create a perfect seal. Warm, humid air keeps entering the walk-in cooler. This air turns into ice in any part of the interior and causes problems.

Faulty Door Mechanism

Gaskets wear with time, but sometimes, the door mechanism may be the culprit of ice buildup inside your commercial walk-in cooler. In some cases, the hinges become misaligned with time and allow some space that proves to be an entering point for warm air.

To check if the hinges are the cause of the problem, look for spaces near the top and bottom of the door.

Aging Or Damaged Insulation Panels

The inside walls of a walk-in cooler are covered with insulation panels. They keep the refrigerator cold by acting as a shield between the warm air outside and the cold air inside. These are sturdy panels, but they are not immune to damage and general wear and tear.

As these panels age more than 10 years, they start losing their insulation properties. This means they can’t keep the warm air outside as effectively as they did before. So, warm air keeps entering the walk-in cooler and turning into ice.

Moreover, due to improper maintenance or carelessness, these panels can be damaged during cleaning, stocking food items, or removing items. This also makes them considerably ineffective.

So, whenever, there is an ice buildup issue, have the insulation panels checked as well. Take note that when the insulation panels of your walk-in cooler are worn, your appliance is probably really old and you should consider replacing the appliance.

Issues With The Evaporator Coil

The evaporator coil is the component that makes your walk-in cooler or any refrigerator cold. The most common issue with evaporator coils is the icing up of the coils due to the issues mentioned above. When warm air enters the walk-in cooler, it can also reach the evaporator coils and its fans. And with time, it can freeze the evaporator coil or the fans.

In some cases, dust and debris buildup can lead to ice buildup in the evaporator coils because these coils make warm air cold. When they can’t due to dirty coils, condensation occurs more than usual leading to frozen coils.

Furthermore, the same will happen if the evaporator coils or their fans are faulty. Sometimes, the fans become faulty due to ice buildup that is because of the inflow of warm air inside the walk-in cooler. This warm air becomes ice. If this is formed on the fans, they won’t rotate, causing the evaporator coils to freeze which will lead to ineffective cooling of the walk-in cooler. This can spoil the inventory stored in the refrigerator.

Keep in mind that the evaporator coil fans can malfunction on their own as well and they will cause the same problem.

Thermostat Issues

In some other cases, evaporator coils become frozen due to thermostat issues. It could be that the thermostat is set to a temperature lower than the recommended settings which will lead to icing up of the evaporator coils.

Apart from that, if the thermostat is faulty, it might not sense the temperature correctly and may not signal the compressor to stop functioning at the right time. The walk-in cooler might start freezing everything or in the opposite case, the walk-in cooler might become too warm.

Malfunctioning Auto-Defrost Cycle

The defrost cycle removes ice from evaporator coils. These cycles are timed and occur periodically. When a defrost cycle is triggered, the compressor is turned off. Evaporator coils are installed with a small heater or heating element that begins functioning and removes ice formed on the coils. Keep in mind that a normal amount of ice formation on evaporator coils is fine and for removing it, the auto-defrost feature is installed.

However, if the defrost cycle doesn’t work or the heating element becomes faulty, the evaporator coils will remain iced up and lead to various problems like cooling issues.

Clogged Drain Line

It was mentioned in the last point that evaporator coils are defrosted. This means the ice on the coils becomes water. This water flows outside the refrigerator through the condensate or drain line. It can become clogged due to a lack of maintenance or something else obstructing the line.

Due to this, melted water from the evaporator coils and other parts of the walk-in cooler won’t be drained out. So, it will pool near the drain line. This water can freeze up.

If you see ice near the drain line only, then the drain line is either clogged or obstructed. So, clean the drain line.

Conclusion

Icing up of the interior of a walk-in cooler is not normal. It’s dangerous and can damage the evaporator coils, evaporator fans, and even the compressor. So, if you notice ice buildup in your commercial walk-in cooler, get assistance from a walk in cooler repair Fairfax technician.
