If your refrigerator coils are dirty, they go into overdrive – meaning larger energy bills and a shorter refrigerator lifespan. Clean them every few months (once a month if you have a pet) to keep your refrigerator in top-notch form.
Shut everything off. Before you start cleaning your coils, carefully slide your refrigerator away from the wall and unplug the appliance.
Find your coils. There are a few places your condenser coils can be located. If you have an old refrigerator (ten years or older) the coils are probably going to be along the back of the fridge. Newer models often have their coils at the bottom of the refrigerator. Note: There isn’t a set-in-stone place for the coils. If you have trouble locating them, consult your owner’s manual for help finding them.
Access your coils. Once you’ve figured out where they’re located, it’s time to get to the coils! If the coils are on the back of the fridge, you should be able to reach them just by moving the refrigerator away from the wall. If they’re under the fridge, access your coils by sliding out the condensate tray. Once it’s removed, you should be able to see your coils. If there isn’t a tray, you can access your coils and just slide them out. Note: This will be different for every refrigerator. Make sure to consult your owner’s manual if your under-the-fridge coils aren’t easy to remove.
Use a towel. If your refrigerator coils look especially dirty, place a piece of cardboard or an old towel on the floor to gather any falling dust.
Grab your vacuum. With a brush attachment, vacuum dust and dirt off of your coils. If your refrigerator fan is visible near your coils, make sure to vacuum it, too. You don’t want dirt and dust on your fan blades because it will decrease airflow!
Dust with a paintbrush. After your vacuum gets most of the dust off of the coils, use a paintbrush to get detailed! Finely brush your coils to get rid of any remaining dust and grime. Tip: If a paintbrush isn’t doing the trick alone, pair it with some canned air! Spray the air on any stubborn places and then brush away the loosened dust.
