Why Ice Is Forming In Your Commercial Refrigerator
While a commercial refrigerator is there to keep your products cold, the last thing you want is for ice to start forming in certain areas of your refrigerator. When this occurs, it's a sign that there is something wrong with your refrigerator and it needs to be repaired immediately.
Frost Buildup in the Commercial Refrigerator
Normally, a commercial refrigerator would have frost that builds up over time. However, the defrost cycle is designed to prevent this. The defrost cycle is controlled by a timer that can be found inside the commercial refrigerator. You may need to adjust the defroster so that it will defrost your refrigerator more often. In some cases, the commercial refrigerator unit is simply defective and you will need to call a repair technician.
If there is frost on everything, you will want to make sure that you haven't turned the thermostat down too much. Also, the thermostat might be defective. If the door was open all night accidentally, this can also cause frost to form everywhere. Allow the commercial refrigerator to run for a few defrost cycles and this will clear away the frost.
Frost Around the Edge of the Door
If frost is building up on the edge of the door, it might not be closing all the way. You'll want to make sure that nothing is blocking the refrigerator door from closing. Also, inspect the door to make sure that it's not defective.
Ice in the Drain Pan
You may also see ice in the drain pan. This often results from the drain line becoming clogged. Then, the water that should be draining turns into ice. Eventually, the unit can start to overheat. You will want to check the line to make sure that there are no obstructions and that no repairs need to be done. Oftentimes, a valve needs to be removed and the drain needs to then be flushed with warm water before the valve is put back into place. However, there might be a part that's broken.
The drain pan itself might be damaged and may need to be replaced. The pan might be misaligned because the fridge is not level. This causes water to spill around the fridge. It's essential that your business keep its commercial refrigerator in good condition, and you should contact a local commercial refrigerator repair technician if you cannot figure out why there is so much ice forming where it doesn't belong.
