Every business owner who relies on commercial refrigeration knows how crucial it is for the unit to function at its peak. However, these refrigerators can sometimes exhibit symptoms that may cause concern. In this blog, we'll discuss some commonly observed issues and their causes, which can help you understand whether your commercial refrigerator is malfunctioning or simply operating normally.
1. Exterior Condensation
If you notice condensation on the outer surface of your refrigerator, don't panic. This is a common occurrence, particularly in areas with high humidity. Simply wipe it dry to prevent any potential water damage.
2. Frost or Ice Beads on the Liner's Back
When the refrigerator is operating, the temperature on the back of the liner often drops below 0 degrees Celsius, causing frost or ice beads to form. They melt automatically once the refrigerator is turned off, which is a normal process.
3. Heat Around the Freezer Door Frame
Experiencing heat around the freezer door frame is not always a sign of malfunction. It's a feature designed to prevent condensation around the door, especially when the air humidity is high.
4. Warm Side Panels
The left and right side panels of the refrigerator may heat up due to the proximity of the condensation radiator. As the refrigerator operates, the heat is dissipated outward, similar to how an air conditioner's outdoor unit dissipates heat in summer. During hot weather, the side panel temperature can reach up to 50 degrees Celsius.
5. Hot Compressor
A hot compressor is not necessarily a malfunction. When the refrigerator is working, the compressor shell's temperature can reach about 80 degrees Celsius.
6. Hissing Sound
A hissing sound from your refrigerator is the sound of the refrigerant flowing in the refrigeration pipe when the system is working. It's a normal part of the refrigeration process.
In conclusion, not all unusual occurrences in your commercial refrigerator indicate a malfunction. Understanding these common phenomena can help you maintain your unit better and prevent unnecessary panic or premature servicing. However, if you observe persistent issues or significant changes in your refrigerator's performance, it's advisable to consult a professiona
