What is this on the back of my fridge? (The black coils intertwining)
That’s will be the condenser.
Warm refrigerant coming out of the Compressor as a gas passes through these coils. The ambient room temperature cools enough so it loses heat as it passed through, condensing the gas to a liquid, and the cooled liquid is then reused through the system.
It is important that these coils are kept clean and clear, with room to 'breathe'.
