What is the proper action if frost reaches a certain level on the refrigerator’s coils?

When frost accumulates on the refrigerator's coils to a certain level, it can disrupt the refrigerator's ability to maintain proper temperatures and operate efficiently. Defrosting the refrigerator, or "reefer," is the appropriate action in this situation. Frost buildup can act as an insulator which impedes airflow over the coils, leading to reduced cooling performance and increased energy consumption.

By defrosting, you remove the frost that has formed, allowing the coils to function effectively again. This process often involves turning off the refrigerator temporarily and allowing the frost to melt away, which can then be cleaned up before turning the appliance back on. Regular maintenance, including defrosting when necessary, is crucial for the longevity and efficiency of refrigeration units.

In contrast, increasing the temperature could exacerbate cooling issues caused by frost buildup, and turning off the refrigerator without defrosting would not resolve the underlying issue. Simply replacing the refrigerator is a more extreme measure that would often be unnecessary if the unit can be restored to proper function through defrosting.
