If your air fryer is suddenly acting strange, this page is the easiest place to start. It brings together the most common problems, the most likely causes, and the safest first steps — so you can stop guessing and get to the right fix faster.

Use this Air Fryer Fix-It guide like a troubleshooting hub. Start with the symptom you notice most, then open the article that matches it best. Each guide is designed to help you check the simplest and safest causes first before moving on to bigger fixes.

If anything looks unsafe — such as smoke from the unit, sparking, a hot plug, melting, or electrical damage — stop there and follow the safety guidance in the relevant article before doing anything else.

Start here if: something feels unsafe or too hot → Quick Safety Checks; the fryer will not turn on or heat → Power & Heating Problems; something smells off or tastes wrong → Smoke, Smell & Taste Problems; food is not crispy or cooks unevenly → Texture Problems; the basket, coating, or parts seem dirty, sticky, or damaged → Cleaning & Parts.
