It should be acknowledged that coil cleaning for refrigerators seldom makes the list until something goes wrong. In fact, one of the most common requests made of service centers is regarding a refrigerator that seems to run constantly, fails to maintain its temperature, or is excessively costly to operate. Dirty condenser coils often are a major cause of poor overall efficiency and cause the system to run harder than it needs to.  

Recently, a homeowner called me because the refrigerator was running constantly for several weeks. As soon as I removed the grille with the expectation of removing some dirt from it, I found that there was dust and animal hair all around the coils. My refrigerator started functioning as it should, and the cooling process got better when I cleaned the coils and restored the flow of air. Many of you have probably not yet cleaned your refrigerator coils. As for the positive, it’s not that hard, and it’s something that you can do on your own. It only takes 20 minutes.

Key Takeaways

  • The dirt on the coils causes inefficiency in the cooling process, and energy consumption increases.
  • In general, coils installed in the refrigerator are to be cleaned at least once every six months or one year.
  • Moreover, in case the place where you live has more than one family residing in it with pets, then coil cleaning becomes more frequent.
  • Cleaning the coils will consume about 20 minutes, and you will require some simple equipment.
  • In general, the position of coils is beneath or behind the refrigerator.
  • It is suggested that you service your refrigerator from time to time.

What Are Refrigerator Coils and Why Do They Matter?

In your refrigerator, magnets are employed, whereas condenser coils that are employed in air conditioners in a condenser unit comprise numerous pipes and fins for cooling the refrigerant when it is operating in the air conditioning system. Clean condenser coils will effectively cool the air conditioning system. On the contrary, dirty condenser coils will make heat rejection very difficult.

Thus, the condensing unit will run for a longer time as a result of the accumulation of dust, debris, and hair in the condenser coils of the air conditioning system. Thus, inefficiency, rise in the cost of energy, damage to the parts of the compressor, and so forth will occur. There are some refrigerator companies that recommend cleaning the condenser coils at certain intervals to ensure efficiency in their performance, especially when you own pets.

What You’ll Need

Before starting, ensure that you have these supplies:

  • Coil cleaning brush
  • Use a vacuum cleaner with a hose attachment to clean.
  • Flat-head screwdriver (also known as a nut driver).
  • Flashlight
  • Dry microfiber cloth
  • Work gloves (recommended)

Many coil brushes can be purchased at the local hardware store or home improvement center. A special cleaning agent or chemicals are not required.

How to Find Your Refrigerator’s Coils

Before you can clean your refrigerator’s coils, you first need to know where they’re hiding. Many models place the coils underneath the appliance, tucked behind a front grille or panel. 

Coils Located Underneath

Coils are typically found under the refrigerator, behind some kick plate, in most modern models, particularly French Door and Bottom Freezer refrigerators. Before cleaning, vacuum the area while the kick plate is removed and use a flashlight to check the area. In many of the models, the condenser assembly is in the form of a small radiator, stuck behind the lower front grill.

Coils Located at the Back

Some refrigerators, older refrigerators, and top freezer models have coils located in the back. Gently remove the refrigerator from the wall to access. Along with this, contaminants and other debris are also dumped around the tubes and fins, which are usually situated on the rear part of the apparatus, and they can also impact the capability of the apparatus to cool.

Follow the Instructions Below to Clean Refrigerator Coils Step-by-Step.

Safety comes first. Before you begin cleaning, disconnect the refrigerator from its power source to protect both yourself and the appliance.

Step 1: Unplug the Appliance. 

The first step is to switch off the power to the appliance. This is mandatory.

Step 2: Remove the Inlay From the Wax. Now, expose the Coils.

Take the fridge out of the kick plate or move the fridge away from the wall (depending on the fridge). With the aid of a flashlight, examine the refrigerator coils and the surrounding area.

Step 3: Wash the Coils in.

Clean accumulated dirt on the fins with a coil brush. Avoid pressing the fins as this may cause them to bend, which will lower the amount of air flowing through them.

Step 4: After the Dirt has been gathered, it’s Time to clean the Dirt with the Vacuum Cleaner: 

Scoop the dirt up with the brush, and then use a hose extension of the vacuum cleaner to collect the dirt. Wipe around the area and clean the floor, fan housing, and around the area.

Step 5: Final Cleanup

Use a microfiber cloth to wipe down the rest of the dust. Make sure water won’t get to the electric appliances.

Step 6: Talk About the Idea of Putting Things in Their Place. Discuss the Concept of Setting Things into Place.

Once switched on again, replace the kick plate and return the fridge to its proper place. That’s all.

How Often Should You Clean Refrigerator Coils?

Most homes will need an annual clean. For those with pets, the coils can be cleaned every 6 months. Pet hair is also prone to piling up, and it can drastically limit air circulation over the condenser assembly. It’s a good practice to have this chore done in spring, since this will make your refrigerator more efficient during the warmest months of the year. While cleaning your refrigerator regularly is a good way for it to run efficiently, it’s also one of the few simple steps that can make your kitchen look and function its best. These are some ideas on other low-cost improvements you can make to refresh your Atlanta kitchen without a full renovation.

Signs Your Coils Need Cleaning

You might be noticing some warning signs that it’s time for a refrigerator repair.

Watch for:

  • Warm exterior surfaces
  • Constant compressor operation
  • If food is not kept cold enough.
  • Higher-than-normal utility bills
  • Over one year since the last clean-up

All the symptoms listed above are indications for a more detailed examination.

Common Refrigerator Coil Cleaning Mistakes I See

I’ve seen in the years that many homeowners just concentrate on the condenser coils and neglect the surrounding area. Cleaning coils is a good thing, but dust and debris on the condenser fan, compressor compartment, and floor under the refrigerator can impede air flow. A refrigerator had a cooling problem, even though its coils were fairly clean, which was one service call that was particularly interesting. The actual problem was a buildup of thick amounts of lint and pet hair around the condenser fan assembly. The area was then cleaned, and air flow was restored, and the refrigerator functioned as normal. I’ve also witnessed homeowners postpone the cleaning of coils for years as the refrigerator still seems to be functioning. 

What makes the situation a problem is that dirty coils typically don’t fail immediately. Rather, they slowly cause the compressor to operate at a higher efficiency over time, causing more wear. In case where the temperature fluctuations persist even after the coils have been cleaned, and frost continues to accumulate, the air conditioner makes strange noises, or there is poor cooling performance, then a problem exists with another component in the refrigeration cycle. For homeowners who need appliance repair in Gainesville, GA, Appliance EMT is a dependable, locally based company that can provide you with reliable diagnostic services for problems associated with your refrigerator that need more than just regular maintenance. They specialize in fixing compressors, fans, thermostats, and sealed system issues.

Gainesville’s Climate and Appliance Wear

There are some environmental factors affecting the maintenance schedule of refrigerators for residents of Gainesville. It is known that in this area there are prolonged warm humid periods, especially in the summer months. At that time, refrigerators were running for longer periods to keep their cooling ability. If there is any obstruction in airflow, the system will become less effective. In addition, we have noticed that homes located close to Lake Lanier, those having attached garages and many pets, accumulate more dust, pollen, and other materials compared to other houses. 

For that reason, annual cleanings of the condenser may not always be sufficient. In our company, Appliance EMT, we often receive service calls related to problems with coils during the summer months. They could be avoided if one were to conduct regular checks and maintenance of his/her equipment. Instead of following all the lengthy guidelines provided by the company, it would be advisable to check the coils twice a year and clean them when a considerable amount of dust accumulates.

Frequently Asked Questions
