Fast diagnosis
| Symptom | Likely cause | First adjustment |
|---|---|---|
| Pale and soft all over | Too much moisture, too little heat or time | Dry food; verify programme and extend gradually |
| Brown outside, cold inside | Pieces too thick or temperature too high | Lower heat and allow more time; verify doneness |
| Crisp on top, soft underneath | Crowding or missed turning | Use a shallower layer and turn or shake |
| Patchy browning | Uneven size or airflow | Cut evenly and redistribute food |
| Food stays soft on a liner | Liner blocks perforations | Use an approved smaller/perforated liner or remove it |
1. The basket is overcrowded
Food needs exposed surface and moving hot air. A physically full basket can still be over capacity for crisp results, especially with fries, wings and breaded foods.
Reduce the batch and compare the exact loading guidance in our how-much-food-fits guide.
2. The food surface is too wet
Water must evaporate before browning can progress. Pat washed vegetables, fresh potatoes and defrosted foods dry. Drain marinades well; very wet batters are usually poor candidates unless the recipe is specifically designed for an air fryer.
3. Pieces are uneven
Small pieces brown while large pieces are still cooking. Cut foods to similar thickness and separate frozen pieces so hot air reaches their surfaces.
4. Temperature or programme is wrong
A preset is a starting point, not proof of doneness. A lower temperature may dry food before crisping; an excessively high temperature may darken the outside too soon. Adjust in small steps and use the manufacturer recipe or food-pack instructions as the first reference.
Use our air fryer cooking-times and temperatures chart as a starting reference, then adapt for food thickness, load and model.
5. Cooking time is too short
Opening the drawer repeatedly releases heat. Check near the end, not every minute, and add time in short increments. Always verify poultry, fish and meat with a food thermometer where appropriate rather than judging safety by crispness.
6. You did not shake, turn or rotate
Multiple layers and fuller loads often need redistribution. Philips says fuller baskets may need more frequent shaking for the models in its support guidance. Delicate food may be better turned with silicone-tipped tongs than shaken.
7. A liner blocks airflow
Foil, baking paper and solid silicone liners can cover basket holes or trap moisture. Only use accessories permitted for your model, keep vents open, and never let loose lightweight material reach the heater.
8. The preparation needs a little fat
Some fresh vegetables and homemade potato preparations brown more evenly with a light, even coating of suitable oil. Many frozen foods already contain oil, so adding more can make them greasy rather than crisp. Follow the recipe or package guidance.
9. Preheating expectations do not match the model
Some recipes assume a hot cooking chamber; some manufacturers say preheating is unnecessary for specified models. Follow the exact manual and be consistent when comparing results.
The air fryer preheating guide explains when a short warm-up may help and when it is unnecessary.
10. Basket shape or appliance design limits the load
A deep narrow basket can force food into layers, while a broad basket exposes more food at once. This does not mean larger litres or higher wattage automatically cooks better.
If repeated small batches are the problem, revisit the air fryer size guide before replacing the appliance.
One-variable troubleshooting method
- Cook the same food and portion.
- Change only one factor: dryness, load, temperature, time or turning.
- Record the result and stop increasing heat once the outside browns too quickly.
- Confirm safe internal temperature separately from texture.
When the appliance may need service
If the fan does not sound normal, the heater does not glow or cycle as expected, error codes appear, or food remains cold despite correct settings, stop troubleshooting recipes. Unplug the unit and use authorised support.
Final recommendation
Start with a drier surface, a smaller shallower load and one planned shake or turn. Then adjust time and temperature gradually. Most crispness problems are easier to diagnose when only one variable changes.
