Defrost heaters are used to melt away ice and frost buildup on refrigeration units, such as refrigerators, freezers, and air conditioners. This helps to improve the efficiency of the unit, prevent damage to its components, and maintain a consistent temperature. Defrost heaters typically consist of coils or electric heating elements that are strategically placed throughout the unit's interior to target areas where frost and ice tend to accumulate. When activated, the defrost heaters generate heat that melts away the ice and allows it to drain away from the unit.
