You probably don’t think much about the way your walk-in cooler works until the day it stops doing its job properly. If you act quickly and know what to do, however, you won’t be left with a fridge full of spoiled food. The freezer repair experts at Dickerson’s Commercial Refrigeration & HVAC have answered a few of the most frequent questions they hear about troubleshooting from their customers in Lexington, KY. 

Walk-In Cooler Troubleshooting FAQ

Why Is the Cooler Freezing Up?

Once you’ve confirmed that your thermostat is set properly, melt all the ice off the evaporator. A quick and easy way to do this is with a hair dryer. If this doesn’t fix the issue, there are a few probable culprits: the evaporation fan may need to be repaired or replaced, the drain line may have a clog in it, or the metering device may be malfunctioning.

Why Is the Cooler Box Leaking?

Leaks are some of the most common problems with refrigeration equipment. The leak will not only make your system less efficient, but it can also become an excellent breeding ground for mold—and puddles on the floor can become a hazard to employees. The issue is usually dripping condensation. Try caulking the seams of the box with a strong, mold-resistant silicone. If it continues to leak, a professional will need to find the problem.

Why Won’t the Cooler Maintain the Right Temperature?

This issue occurs when the unit is running, but just won’t get cold enough. This can spoil your food and waste energy, as the cooler runs constantly at its highest setting. First, check that the door is sealing properly when it’s shut. If cold air is escaping through the door, you’ll need to have the gaskets replaced. Otherwise, the temperature control may need replacement or the system may just need a cleaning.

Why Won’t the Unit Turn On?

Begin by checking that the unit is plugged in and the switch is in the “on” position. Next, check that the outlet has power by testing another appliance. If the system is getting power but it’s not turning on, there may be broken or loose wires in the unit.
