Why is My Commercial Refrigeration Unit Not Cold Enough?

A commercial refrigerator can last as long as 20 years with proper care and maintenance. Part of caring for your unit is addressing different needs and issues over its life. Temperature is a common issue for most commercial units. However, the temperature is rarely the definitive problem. Most times, it results from faulty mechanisms that need repairing or replacement. If your commercial refrigerator is not cold enough, here is a commercial refrigeration troubleshooting guide to determine the primary source of the problem.

Power Problems

Although it might be silly to ask, “Is the power cord plugged in?” Even if the plug is partially out of the wall socket, the unit can lack the necessary power to cool its contents.

An unplugged or partially unplugged unit could mean the motor is cycling between on and off, resulting in uneven cooling times and temperatures. Even if a plug is all the way in, check the outlet itself. Sometimes outlets need replacing.

Air Circulation

Air circulation is a common oversight for commercial refrigerators. There are two ways to look at this problem–the back panel and inside the unit.

When looking at the back panel, pay close attention to its distance from the wall. If it’s right up against the wall, there isn’t enough room for the hot air to circulate, so it’s warming the unit.

Now check inside the commercial refrigerator. An overpacked unit limits cold air travel. Air circulation is essential for proper cooling and freezing.

Temperature Control Gauge

All commercial refrigeration equipment has a temperature gauge, so you need to check that it’s working. With the gauge set, use another thermometer to check if it’s accurate. If the unit is warmer than the setting on the gauge, your temperature control system needs repair.

Gaskets

One of the best ways to ensure proper cooling is with gaskets. What appears to be harmless seals around the door can be the difference between spoiled and fresh produce.

If there are damaged seals on your commercial freezer (i.e., tears, holes, missing gaskets), your unit is losing the cool air faster than it can replenish it. All you have to do is replace the seal with a new door gasket, and your refrigeration unit should maintain the proper temperature.

Conclusion

After investing thousands of dollars into a unit, you must take proper care of it. Otherwise, you risk having to replace it before you’re ready. If your unit suffers from common commercial refrigeration problems, like warm air, check the outlet and air circulation, monitor the temperature gauge, and replace the door gaskets.
