Hard work isn’t always visible. That’s the case with your fridge; while it works hard every day to keep your food fresh, it often gets neglected due to elements that are out of sight. One of these parts is the condenser coils behind or under your fridge. These hidden coils help release heat after collecting it from the refrigerant. When they’re covered in dust, your fridge has to work overtime.
This wastes a lot of energy that you could be saving money on, but also shortens the lifespan of your fridge. So, how often should you clean your fridge coils? We’ll give you a little breakdown to answer the what, why, and how!
Signs You Need To Clean Your Refrigerator Condenser Coils
It’s easy to forget about fridge coils since they’re usually tucked away at the back or bottom of your refrigerator. But your appliance will start sending you little signals when it’s time to clean your fridge coils or when it might be time to call a trusted fridge repair expert:
- The motor runs constantly: If you hear your fridge buzzing or humming more than usual, that means the compressor is running for longer, the fan is working overtime, and there’s strain on all fridge parts. Clogged coils could very much be the reason this is occurring.
- Your fridge feels warmer than it should: Dust buildup makes it harder for the refrigerator system to stay cool. When dust builds up on the coils, it acts like a blanket. The coils are supposed to release heat into the room air, but if they’re covered, they can’t get rid of that heat as effectively.
- Your energy bill has spiked: Dirty coils force the fridge to work harder, using more electricity.
- You see dust bunnies or pet hair around the base: That’s a sure sign the coils need attention.
If you notice any of these issues, it’s a clear reminder to clean your fridge coils before the problem gets worse.
How To Keep Your Fridge Coils Clean
We recommend cleaning coils every six months, but if you have pets or a dusty home, you’ll need to do it more often, about every three to four months.
Materials & Safety Precautions to Take Before Cleaning
Before you start, grab a few simple items:
- A vacuum with a hose attachment
- A coil cleaning brush (affordable and easy to find)
- A flashlight so you can see hidden spots
- A screwdriver that matches the screws on your refrigerator panels (if needed)
Safety is extremely important. If you’re not confident cleaning these coils on your own, we have expert appliance repair technicians who are more than happy to help. Always unplug the refrigerator before you begin. This prevents accidents and any other dangers that might arise from electricity.
Step-by-Step Fridge Condenser Coils Cleaning Guide
This guide will vary based on the fridge you have. For example, Bosch fridges usually hide the condenser coils at the bottom of the fridge, while Frigidaire fridges have the coils placed behind the rear panel.
To get more clarity, check the fridge’s manual to better locate the condenser coils. However, these are the general guidelines for cleaning your condenser coils.
- Unplug the refrigerator. Never skip this step; it keeps you safe from any electrical hazards in Mecklenburg Country (which includes Charlotte).
- Locate the coils. They’re usually behind a panel or grill at the bottom or on the back of the fridge.
- Use your screwdriver to safely remove the panel (if necessary).
- Use your vacuum. Gently run the hose over the coils to suck up loose dust and hair.
- Brush between the coils. A coil brush bends to reach tight spaces, knocking loose dirt that the vacuum can catch.
- Make sure all dirt or debris on the ground near the coils is vacuumed as well. This will guarantee none of it gets stuck to the coils when you push your fridge back into its spot.
- Vacuum again. Go over the area a second time to grab any debris that came loose.
- Replace the panel and plug the fridge back in.
Cleaning should take no more than 20 minutes and will instantly help your fridge run better!
Cleaning Your Condenser Coils Successfully
Taking the time to clean your fridge coils every few months is one of the most time-efficient and easy ways to extend its life and save money on energy bills. Still, if you’ve done the cleaning and your fridge continues running loudly or struggles to stay cold, it might be time to call a repair technician at Just Call. While we’re checking your coils, we can also check for any other problems that you might not have noticed yourself.
Dirty condenser coils can make your refrigerator use up to 25% more electricity. Because the coils cannot release heat efficiently, the compressor has to run longer to keep the interior cool, which drives up your energy bill every month.
On most modern refrigerators, the condenser coils are located at the bottom of the unit behind the front kick plate or grille. Older models and some French door fridges have coils at the back. Check your owner’s manual if you are unsure, or look for a black grid of metal tubing when you remove the kick plate.
Frequently asked questions
How often should I clean my refrigerator condenser coils?
Clean your condenser coils at least once a year. If you have pets that shed, clean them every 6 months. Pet hair is especially effective at clogging coils and can noticeably affect cooling performance within just a few months in a high-shedding household.
Can dirty condenser coils cause my fridge to stop cooling?
Yes, severe coil buildup can cause the fridge to struggle maintaining temperature, especially in warm weather. You will often notice the fridge running constantly, food spoiling faster than usual, or the freezer struggling to keep things frozen. If cleaning does not restore performance, there may be a deeper issue. Our Charlotte fridge repair team can diagnose it.
Do I need to unplug my refrigerator before cleaning the condenser coils?
Yes, always unplug the refrigerator before cleaning the condenser coils. The coil brush and vacuum can contact electrical components, and you want the compressor off during cleaning. This is a basic safety step that only takes a moment.
