How to do it — step by step
Unplug the refrigerator. Access condenser coils from the front bottom (remove the grille) or from behind. Use a coil brush or vacuum attachment to remove dust and debris. Dusty coils force the compressor to work harder, increasing energy use and shortening the compressor's life. A refrigerator compressor replacement costs $400–$800, about the cost of a new fridge.
