3 Warning Signs That Mean It's Time To Replace Your Air Fryer

According to the National Frozen & Refrigerated Foods Association, air fryers can be found in 71% of American households. Like other kitchen appliances, these commonplace devices require regular maintenance to ensure consistent performance and reduce the rate of wear. Though cleaning and care are crucial, all air fryers must be replaced eventually, and knowing the signs of a dying device lets you secure a quick replacement. Air fryers can experience all sorts of problems, but we're focusing on three key issues: performance, safety, and features. 

Defective components can stop your food from cooking through, leaving some areas overdone and others uncooked. They can also pose a serious risk of injury and fire. If you have a still functional older model, you could be missing out on the helpful, inventive features of modern air fryers. For instance, hybrid devices offer several cooking functions in one, like toasting and baking. If you're primed to start shopping for a new air fryer, Consumer Reports named these retailers the best for small appliances.

Unlike microwaves, which are never beating the soggy food allegations, air fryers are beloved for the ability to make food crispy (even though they don't technically fry anything). Similar to convection ovens, air fryers have fans that disperse hot air around food, which results in even heating and crispier textures. This hot air is generated by a heating element inside the appliance, which is often a metal coil, though some high-end models use carbon fiber infrared or ceramic‑based PTC heating elements. 

Problems with the heating element can manifest in a few ways, but there are two that are pretty hard to miss. A faulty element can fail to generate any heat at all or produce heat inconsistently. Some parts of your food may be cooked while other parts are still cold. It can also take longer to cook food when the heating element is failing. When dealing with defects, you might consider repair over replacement. However, it's usually more cost effective to buy a new device. Although higher end appliances can be on the expensive side, you can find reliable budget air fryers for as little as $69.

Electrical safety probably isn't top of mind when making BBQ chicken tenders in your air fryer. It's true these appliances are very safe, but defects and wear can create a hazardous environment in your kitchen when they affect electrical components. Problems with wiring and heating elements carry a fire risk and can also lead to injuries resulting from burns and shocks. Device sparking is a major indicator of electrical faults and can be accompanied by bad odors (like burning plastic) and buzzing noises.

Electrical sparking has some telltale characteristics to watch for that differentiate it from food-related flare-ups. Blue arcs or sparks jumping from the outlet, plug, cord, or the air fryer's electrical components signal you should stop using the air fryer immediately and unplug it if it's safe to do so. This is not the same as a brief flash inside the cooking chamber caused by grease or food debris, which can happen when food makes contact with the heating element. In that case, you can unplug the air fryer and give it a thorough cleaning to resolve the issue. If you're not sure or don't want to risk it, it's always best to err on the side of safety and contact the manufacturer or a professional electrician.

While it depends on factors like maintenance and frequency of use, most air fryers have a lifespan ranging between three and five years. As time goes on, you may notice decreased performance or overheating, which signal the device's time is nigh. However, it may be worth updating your air fryer even if it isn't showing obvious signs of wear. Newer models have helpful functions and features that are missing in many older appliances.

Digital controls are a big upgrade over analog, especially when they give you smaller degree increments for more precise cooking. If your current model takes up too much counter space, there are small, streamlined devices perfect for compact kitchens. You might also consider making the switch to a glass air fryer, which eliminates concerns about PFAS leaching into food. Glass baskets also tend to last longer than non-stick, and they're good for storing food at the end of your air fryer feast.
