Smoke halfway through dinner is a reason to stop and check the appliance. You do not have to decide immediately whether it is old grease, a stray crumb or a fault. Deal with the immediate situation first; troubleshooting can wait until the air fryer is safe to inspect.
If an air fryer starts smoking unexpectedly, switch it off and unplug it if safe to do so. If there is a fire, get out, stay out and call 999; never use water on an air-fryer fire. Once the appliance has cooled and there is no fire, check the manual for cleaning and troubleshooting instructions. Do not restart an appliance that appears damaged.
Stop before trying to diagnose the colour
Hereford and Worcester Fire and Rescue Service advises switching off and unplugging an air fryer if it smokes, sparks or overheats, provided it is safe to do so. Do not reach through smoke or flames to get to a socket.
For an actual fire, leave the building and call 999 from safety. Do not carry the appliance outside or pour water into it. Follow the fire service advice rather than attempting to finish the meal. Smoke colour alone cannot establish that the appliance is safe.
Check the pan for grease after it has cooled
Philips identifies fatty ingredients and greasy residue from earlier cooking as possible causes of white smoke in its air fryers. Look at the pan beneath the basket as well as the surface that held the food. A drawer can look tidy from above while retaining grease below.
Do not wipe or empty hot fat while investigating. Wait until the appliance is cool and follow your model instructions. If your model uses a supplied fat-reducing accessory, check its required position in the manual; do not substitute an accessory intended for another appliance.
Smart tipWhen contacting support, have the model number ready and describe what was cooking and whether the drawer had been cleaned. A clear account is more helpful than repeated attempts to reproduce the smoke.
Look for loose coating or light food
Philips also notes that detached breading and light ingredients lifted towards the heating element can cause smoke. Once everything is cool, check accessible areas using the inspection and cleaning method in the manual. Never dismantle the appliance to reach a suspected obstruction.
For the next supported cook, check how the coating should be applied and whether the food is suitable for your model. Do not improvise a cover to hold loose food down. Use an accessory only when the manufacturer specifies it for that appliance.
Clean the parts using the right method
Philips recommends hot water, washing-up liquid and a soft sponge for its removable pan and basket, and warns against metal tools or abrasive cleaners on the non-stick surface. Other models may have different washing restrictions, so check before using the dishwasher.
Cleaning the removable drawer is different from cleaning the electrical body or heating area. Follow the model instructions for each part, allow it to dry as directed and reassemble it correctly. A social-media cleaning trick is not a replacement for the manual.
Know when to leave it switched off
If smoke returns, or you notice damage, sparks or overheating, leave the appliance off and contact the manufacturer. Explain what you have checked. Do not keep restarting it to see whether the problem disappears.
Before returning a working appliance to normal use, check its location too. Keep it away from items that could catch fire and give it the clearance specified in the manual. London Fire Brigade has reported a house fire believed to have started because items were placed too close to an air fryer.
Air fryers vary in power and basket design. Use these timings as a starting point and follow your manufacturer’s instructions where they differ.
Frequently asked questions
Is white smoke always harmless?
No. Philips lists food-related causes of white smoke, but that does not diagnose every appliance. Stop unexpected smoke, inspect only when safe and follow the guidance for your model.
Should I add water to stop the smoke?
Never use water on an air-fryer fire. Do not improvise by pouring water into a hot or smoking appliance. Follow the manufacturer method once it is switched off, cool and safe to inspect.
Can I restart after cleaning?
Follow the model troubleshooting instructions. If the cause is unresolved, smoke returns or there are signs of damage, keep it switched off and ask the manufacturer for advice.
