The heating coil needs cleaning when you see browning or buildup
The heating coil in your air fryer sits at the top of the basket chamber and browns food by radiating intense heat downward. Over time, grease splatters, food particles, and burnt residue stick to it. When the coil gets dirty, it heats unevenly, your food cooks slower, and you may see smoke or smell burning during use. Cleaning it takes 15 to 30 minutes and requires only items you already have at home.
Most air fryer coils can be cleaned while still inside the machine. A few models have removable coils, but the majority do not. Either way, the process is straightforward: unplug the unit, let it cool completely, then use a soft brush or cloth with warm soapy water to loosen and wipe away the buildup. Never use abrasive scrubbers or harsh chemicals, which can damage the heating element.
Key Takeaways
- Always unplug the air fryer and wait at least 30 minutes for the coil to cool before touching it.
- Use a soft-bristled brush, damp cloth, or soft sponge with warm soapy water to clean the coil in place.
- Avoid steel wool, scouring pads, vinegar, and abrasive cleaners, which can scratch or corrode the heating element.
- If your model has a removable coil, check your manual first — removing it incorrectly can damage the electrical connections.
Step-by-step cleaning for a coil that stays in place
Start by unplugging the air fryer from the wall outlet. This is non-negotiable: working on a plugged-in appliance risks electric shock. Let the unit sit for at least 30 minutes so the coil cools completely. Touch the coil gently with your finger — it should feel warm at most, not hot.
Fill a small bowl with warm water and add a few drops of dish soap. Dip a soft-bristled brush (an old toothbrush works well) into the soapy water and gently scrub the coil in circular motions. Pay attention to the grooves and ridges where grease collects. For stubborn spots, let the soapy water sit on the coil for two to three minutes before scrubbing again.
Wring out a clean, damp cloth and wipe the coil to remove soap residue and loosened debris. Use a dry cloth to pat it dry. Do not pour water directly onto the coil or submerge it. Once the coil is dry, plug the unit back in and run it at 350°F for three to five minutes with the basket empty. This dries any remaining moisture and confirms the coil still heats evenly.
Removing and cleaning a detachable coil
Some higher-end models, including certain Cosori and Ninja units, have coils that unscrew or slide out. Check your manual before attempting removal — the exact method varies by brand. If your manual does not mention coil removal, do not force it. A coil that appears stuck may have safety clips or electrical connections you cannot see.
If removal is safe for your model, unplug the unit first and let it cool. Locate the screws or clips holding the coil in place, usually at the top corners of the basket chamber. Remove them carefully and set them aside in a small container so you do not lose them. Gently lift the coil straight up and out. Do not twist or bend it.
Clean the removed coil the same way: warm soapy water, soft brush, and a damp cloth to rinse. Dry it completely with a cloth before reinstalling. Align the coil with the mounting points, lower it into place, and tighten the screws or clips by hand first, then snug them with a screwdriver. Do not overtighten, which can crack the coil or strip the threads.
What not to use when cleaning the coil
Steel wool, scouring pads, and abrasive brushes scratch the coil's surface and expose the metal underneath to corrosion. Once the protective coating is damaged, rust can form and eventually cause the coil to fail. Vinegar and other acidic cleaners also corrode the heating element over time, even though they may seem to work in the short term.
Harsh commercial degreasers and oven cleaners are too strong for air fryer coils and can damage the electrical insulation. Bleach and ammonia-based cleaners pose the same risk. Stick to plain dish soap and water. If you need extra cleaning power, a paste of baking soda and water is safe and effective for stubborn burnt-on spots. explore it, let it sit for five minutes, then scrub gently and rinse.
How often to clean the coil
Clean the coil every 20 to 30 uses if you cook fatty foods like chicken thighs, bacon, or frozen fries regularly. If you mostly cook lean proteins and vegetables, every 40 to 50 uses is usually enough. A visual check takes 10 seconds: open the basket and look up. If you see brown or black buildup, it is time to clean.
Keeping the basket and tray clean also reduces coil buildup. Grease that splatters onto the basket can travel upward and stick to the coil. Wipe the basket and tray with a damp cloth after each use, and wash them with warm soapy water once a week. This straightforward habit cuts the frequency of coil cleaning in half.
Signs the coil needs replacement instead of cleaning
A coil that has been cleaned properly should heat evenly and produce consistent results. If you clean the coil and food still cooks unevenly — burnt on one side, undercooked on the other — the heating element itself may be failing. If the coil no longer heats at all, or if you see visible cracks, rust, or corrosion that does not come off with gentle scrubbing, replacement is the only option.
Replacement coils are sold by the manufacturer and usually cost between $30 and $80, depending on the model. Check your air fryer's manual or the manufacturer's website for the correct part number. Installation typically involves removing the old coil and screwing in the new one, a task most people can do in under 10 minutes. If you are not comfortable doing it yourself, a small appliance repair shop can install it for you.
Frequently Asked Questions
Can I use vinegar to clean the air fryer coil?
No. Vinegar is acidic and corrodes the heating element over time, even though it may seem to clean well at first. Stick to warm soapy water with dish soap. If you need extra cleaning power, a baking soda and water paste is safe and works just as well.
What if water drips onto the heating element while I am cleaning?
Let the unit dry completely before plugging it back in. Run it empty at 350°F for three to five minutes to evaporate any remaining moisture. If water got inside the electrical housing (not just on the coil itself), unplug it and let it sit for 24 hours before trying again. When in doubt, wait longer.
Is it safe to clean the coil while the air fryer is still plugged in?
No. Always unplug the unit before cleaning any internal parts. Even if the coil is not actively heating, touching it while plugged in poses a shock risk. Unplugging takes five seconds and eliminates the danger entirely.
My air fryer coil looks corroded. Can I clean that off?
Light surface discoloration usually comes off with gentle scrubbing and warm soapy water. If the corrosion is deep, pitted, or flaking, the coil has been damaged and cleaning will not restore it. A corroded coil that still heats may work for a while, but it will eventually fail. Consider replacing it to avoid a breakdown mid-cook.
Do I need to remove the basket to clean the coil?
No. You can clean the coil with the basket in place. straightforward tilt or angle the basket slightly to access the coil from above. Removing the basket gives you more room to work, so if you have the space, it makes the job easier — but it is not required.
