Keep the compartment behind the back panel of your refrigerator clean and your appliance may run more efficiently and last longer. As dust collects on the compressor, cooling fan and wires inside the rear-base of your refrigerator, a number of problems can occur. The fan can get noisier and the dust can over-insulate parts that need to remain clean for proper cooling to take place. A dirty environment is also the perfect habitat for bugs and mice. Once you can reach the back of the fridge, removing the back panel doesn't require much effort.
Pull the refrigerator away from the wall. Most refrigerators are on wheels, but you still might need a helping hand if it's too hard to move by yourself.
Unplug the power cord from the power outlet.
Locate the screws that hold the back panel in place.
Remove the screws with a flathead or crosshead screwdriver.
Grab the end corners of the panel with your fingertips. Pull up and out to remove the panel from the bottom track of the fridge.
