Before we jump into the causes, let’s clarify the crucial role of the fuse in your AC system. Think of the fuse as a safety valve. Its primary function is to protect the delicate electrical components of your AC unit from damage caused by excessive current flow. When the current exceeds the fuse’s rated amperage, the fuse "blows," interrupting the electrical circuit and preventing potential damage to the compressor, fan motor, and other vital parts. Without a properly functioning fuse, these components are vulnerable to overheating, short circuits, and ultimately, costly repairs or even complete failure.
