BEFORE YOU BEGIN

Before you begin. This procedure is general reference information, not professional advice. Equipment varies by manufacturer, model, and year. Always follow the documentation supplied with your equipment — where it differs from this page, follow the manufacturer. Verify that you have the tools, the working conditions, and the ability to do this task safely. If anything is unclear, if the equipment is damaged, or if the task exceeds your experience, stop and use a qualified professional. You are responsible for your own safety and for the outcome. This site accepts no liability for any loss, damage, or injury arising from the use of this information.

Specifications marked unverified could not be traced to a manufacturer source. Do not rely on them — obtain the value from your equipment documentation.

Summary

The condenser coils are the part of a fridge that dumps heat back out into your kitchen, and on some models they sit in the open where dust, pet hair and cooking grease settle on them. When they load up, the compressor runs longer and hotter to do the same amount of work. The job takes about forty minutes of which most is waiting, needs nothing more than a vacuum cleaner and a coil brush, and the only real skill involved is not bending anything.

The first thing this page does is send you to your own documentation to find out whether your fridge has coils you are supposed to touch at all. Plenty do not. GE Appliances says most of its models built since 2001 have an enclosed condenser that never needs cleaning, and Whirlpool says some models can only be cleaned by a certified technician. The cleaning interval is the same story: the manufacturers checked for this page do not agree with each other, so both answers are printed below with their names against them instead of being averaged into one tidy number. Everything after that is sequence, and the sequence matters — the appliance comes off the power first, because the fan in that compartment starts on its own with no warning at all.

Condenser coil cleaning interval
Unverified — do not rely on this value
CONSULT THE MANUFACTURER DOCUMENTATION FOR THE INTERVAL

No tier-1 source was found for this value. Take it from the documentation supplied with your equipment.

Three tier-1 manufacturer and government sources give three different answers to the same question, and this page publishes all three rather than choosing. Whirlpool (whirlpool-condenser-coil-cleaning, accessed 2026-07-29) says that in a normal home routine condenser cleaning is not typically needed, and gives an inspect-and-clean interval of every 3 to 6 months only for households with pets, heavy kitchen traffic or construction dust. Samsung (samsung-refrigerator-cleaning-plan, accessed 2026-07-29) puts the condenser coils inside an annual deep clean. GE Appliances (ge-refrigerator-condenser-coil-cleaning, accessed 2026-07-29) publishes no interval at all and says most models made since 2001 have an enclosed condenser that does not require cleaning. ENERGY STAR (energystar-refrigerators, accessed 2026-07-29) also gives no interval and routes the reader to the manufacturer's manual. These are not the same number written three ways; the underlying equipment genuinely differs. Use the interval in the documentation for your own model.

Terminology

This page uses one term for each item and holds it throughout, as ASD-STE100 requires. Equipment sellers and other guides use the names below for the same parts.

condenser coil
Also called: fridge coils, refrigerator coils, the coils under the fridge, cooling coils, radiator coils, compressor coils, the black thing under the fridge
base grille
Also called: kick plate, kickplate, toe kick, bottom vent, front grill, the panel at the bottom of the fridge
machine compartment
Also called: compressor compartment, mechanical compartment, motor compartment, the back of the fridge, the bit underneath
condenser fan
Also called: the fan under the fridge, cooling fan, compressor fan, condenser fan motor
fin
Also called: coil fins, radiator fins, the metal blades on the coils, the sharp bits

When to use a professional

Stop if the documentation says that only a certified technician can clean the condenser. Some models have a condenser that the owner must not touch.

Stop if you find oil or a wet area on the condenser coils or below them. Do not do work on the sealed refrigerant circuit, because that work needs certification. Speak to a certified appliance technician.

Do not remove the cover of the machine compartment, because damage to the refrigerant pipes can result. LG gives this instruction for its own models. The same care applies to every refrigerator.

Stop if the refrigerator does not become cold again after this work. A fault in the cooling system is not part of this procedure. Speak to a certified appliance technician.

Common questions

How often should I clean my refrigerator coils?

The sources this page rests on do not agree, so we print all of them rather than splitting the difference. Whirlpool says that in a normal home routine condenser cleaning is not typically needed, and gives every 3 to 6 months only for homes with pets, heavy kitchen traffic or construction dust. Samsung folds a check of the condenser coils into an annual deep clean. GE Appliances gives no interval at all, because it says most of its models since 2001 have an enclosed condenser that never needs it. ENERGY STAR also declines to give a number and tells you to read your own manual, which is the honest answer and the one we repeat here.

Do I even need to clean my fridge coils?

Quite possibly not, and this is the part most pages skip. GE Appliances says most refrigerator models it has made since 2001 have what it calls a NeverClean condenser, encased so that the coils will not require cleaning under normal conditions. Whirlpool says some of its models do not require it either, and that on others the condenser can only be cleaned by a certified technician. Your documentation is the only thing that can tell you which of those you own. If it says the condenser is enclosed or is a technician job, you are finished before you start.

Where are the condenser coils on a refrigerator?

GE Appliances lists three places: under the fridge behind the base grille, on the back, or on the top. Which one you have depends on the model and roughly on its age, and it changes the job completely — a front grille means you kneel down and never move the appliance, while rear coils mean pulling the fridge out and watching the water line behind it. Look it up before you start shifting furniture.

Do I really have to unplug the fridge first?

Yes, and it is the one instruction on this page that both manufacturers state flatly. GE says to always unplug the refrigerator from the power supply before attempting any maintenance or cleaning. Whirlpool says to unplug it or switch off the circuit breaker before cleaning. The reason is the fan sitting in that compartment: it is thermostatically controlled, so it starts on its own with no warning and nothing you do at the front of the appliance stops it.

Will my food spoil while the fridge is unplugged?

Not for the length of this job, provided you keep the doors shut. A closed domestic fridge holds its temperature for a good while with no power, and this procedure takes well under an hour. Do not use the opportunity to reorganise the shelves with the door hanging open.

What happens if I bend the fins?

Bent fins block the air that has to pass between them, which is the opposite of what you came to do. Whirlpool's own guidance is to avoid bending fins or tubing. Use light pressure, brush along the fins rather than across them, and if you find fins already flattened, ask a technician rather than trying to comb them straight.

Can I use a leaf blower or compressed air instead?

You can move a lot of dust that way, but you will move it into the room and into the rest of the machine compartment rather than out of it. A vacuum cleaner takes the dust away, which is the point. If you do blow the coils out, do it somewhere the dust can settle harmlessly and expect to vacuum afterwards anyway.
