How to Install an Overload Protector to a Fridge Compressor

The overload protector on a fridge prevents damage to the compressor motor by restricting the flow of current. The protector shuts down like a fuse if the power demand exceeds the capacity of the overload protector. This safety feature helps avoid more extensive damage. Installing the overload protector involves moving the fridge, typically one of the heaviest appliances in a home. Enlist a friend's help to move the fridge so you can install the overload protector.
