Key Takeaways
- If your air fryer is not working, start with safety first: turn it off, unplug it, and let it cool.
- Check the plug, power cord, outlet, basket, drawer, and control panel before assuming it needs repair.
- If the appliance turns on but is not heating, the issue may involve the heating element, sensor, fuse, or overheat protection.
- Error codes like E1 and E2 are model-specific, so check the manufacturer’s manual before trying to diagnose the problem.
- Stop using it if you notice any damage, burning smell, unusual noises, crack, rattle, moisture, or electrical problems.
Direct Answer
Your air fryer may not be working because of a loose plug, bad outlet, damaged cord, misaligned basket, blocked vent, overheating protection, dirty heating element, faulty sensor, blown fuse, or internal electrical fault. Start with safe checks you can do at home, then stop and contact support if the appliance still fails.
How an Air Fryer Works
An air fryer is a countertop cooking appliance that uses a heating system and fan to move hot air around food. USDA explains that air fryers are essentially countertop convection ovens, and after the user turns one on, hot air is released through the heating mechanism. [USDA FSIS]
This matters because most common issues are related to three things:
- Power is not reaching the appliance.
- The basket, drawer, or safety switch is not seated correctly.
- The heating element, fan, sensor, or control board is not working properly.
If the air fryer circulates hot air normally, food cooks fast. If that airflow, heat, or power source fails, the unit may stop working.
Safety First Before You Troubleshoot
Before you troubleshoot, unplug the air fryer and let it cool. Do not open the appliance body or touch electrical components unless you are qualified to repair small appliances.
Stop using the unit if you notice:
- Melted plug
- Damaged power cord
- Burnt smell
- Smoke from the control panel
- Crack in the basket or housing
- Moisture inside electrical areas
- Loud rattle from the fan area
- Display error codes that do not clear
- Unusual noises after reset
If you see any of these signs, do not try to fix an air fryer by forcing it back to life. Contact the brand or buy a new unit if repair is not safe or cost-effective.

Quick Troubleshooting Table
| Problem | Possible cause | What to check |
|---|---|---|
| Air fryer will not turn on | Loose plug or bad outlet | Test another outlet |
| Air fryer not heating | Heating element, sensor, or fuse issue | Check manual and error codes |
| Air fryer starts then stops | Basket or drawer not fully inserted | Reinsert basket firmly |
| Display works but no heat | Faulty heating system | Contact support |
| Error E1 or E2 | Sensor or circuit issue | Check model-specific manual |
| Unit shuts off | Overheat safety feature | Let it cool and inspect vents |
| Burning smell | Grease, debris, or food particles | Clean basket and heating area |
| Fan rattles | Debris or loose part | Stop and inspect safely |
Troubleshooting Guides
1. Check the Plug, Cord, and Outlet
The first thing to check is power. Make sure the plug is fully inserted into the outlet. Then inspect the power cord for cuts, melted areas, loose wiring, or heat damage.
Try this step-by-step:
- Unplug the appliance.
- Inspect the cord.
- Plug another kitchen device into the same outlet.
- Test the air fryer in a different outlet.
- Avoid overloaded extension cords.
- Check your home circuit breaker.
If the outlet is dead, the problem is not the air fryer. If the outlet works but the air fryer still does not power on, the problem may be inside the appliance.
Some manuals also warn against using outlets below a counter or overloaded power setups. This matters because air fryers draw high amperage compared with many small kitchen gadgets.
2. Make Sure the Basket or Drawer Is Fully Inserted
Many basket-style air fryers have a safety switch that stops the unit from running if the basket or drawer is not properly seated. If the basket isn’t fully inserted, the appliance may not start.
Check these areas:
- Basket alignment
- Drawer rails
- Crisper tray position
- Food blocking closure
- Crumbs stuck near the switch
- Bent basket handle
- Overfilled basket
Remove the basket, check for debris, and slide it back in firmly. If the fryer won’t start after that, try removing some food and closing it again.

3. Check the Control Panel, Button, Dial, or Display
If the control panel lights up but the air fryer does not start, the problem may be a setting, locked control, button issue, or display error.
Check:
- Power button
- Start/pause button
- Temperature setting
- Timer setting
- Dial position
- Basket warning icon
- Error code
- Child-lock setting if your model has one
Some models will not begin heating until you press Start after choosing time and temperature. Others pause automatically if the drawer is opened.
4. Why Is My Air Fryer Not Heating?
If the fan works but the air fryer is not heating, the problem may be the heating element, thermal fuse, internal sensor, or control board. A dirty heating area can also reduce heating performance.
Possible causes include:
- Faulty heating element
- Failed thermal fuse
- Broken temperature sensor
- Grease covering the heat area
- Overheat protection activated
- Internal circuit problem
- Food touching the heat source
- Blocked air inlet or outlet
Mi Support says E1 or E2 on some Mi Smart Air Fryers can indicate a temperature sensor or heating element issue. [Mi Support] KitchenAid also says E1 or E2 on its countertop air fryer may mean the NTC sensor is not working. [KitchenAid Product Help] Because error meanings vary, always check your model manual before replacing parts.
5. Let the Appliance Cool After Overheating
Some air fryers stop working because an overheat safety feature activates. This may happen if vents are blocked, the basket is overloaded, grease builds up, or the unit sits too close to a wall.
To reset safely:
- Turn it off.
- Unplug it.
- Let it cool for 20–30 minutes.
- Remove the basket.
- Inspect vents for blockages.
- Clean grease and food particles.
- Plug it back in.
- Test with an empty basket.
If it overheats again, stop using it. Repeated overheating can point to a faulty sensor, heating system, or electrical problem.
6. Clean Grease, Debris, and Food Particles
Grease and debris can make an air fryer smell, smoke, heat unevenly, or stop working properly. Regular cleaning helps protect the basket, tray, rack, heating area, and fan path.
Clean these areas:
- Basket
- Drawer
- Crisper tray
- Rack
- Bottom pan
- Heating element area
- Air outlet
- Food crumbs near switches
Do not pour water into the appliance. Use a soft damp cloth after the unit is unplugged and cool.

7. Check for Error Codes Like E1 and E2
Display error codes can help diagnose the issue, but they are not universal. E1 on one brand may mean a sensor issue, while another brand may use the same code differently.
For example:
| Code | Possible meaning | What to do |
|---|---|---|
| E1 | Sensor, open circuit, or model-specific fault | Check manual |
| E2 | Sensor, heating, or short circuit fault | Contact support if it stays |
| E3 | Overheat protection on some models | Cool, reset, and inspect |
| Err2/Err3/Err4 | Brand-specific fault | Follow manufacturer’s guide |
A COSORI manual example lists E1 as an open circuit in the temperature monitor and E3 as overheat protection on one dual-basket model. [COSORI manual via ManualsLib] Philips also says its Airfryer error codes depend on the model and cooking program. [Philips Support]
The safe rule: do not guess. Use the manufacturer’s model-specific guide.
8. Inspect the Heating Element
The heating element is the part that creates heat. If it is coated with grease, damaged, cracked, or not glowing when expected, heating may fail.
After the unit cools and is unplugged:
- Look for heavy grease.
- Check for loose food particles.
- Do not bend the heating element.
- Do not scrape it with metal.
- Do not spray cleaner directly on it.
- Do not use the unit if you see damage.
If the heating element looks broken or the appliance has stopped heating completely, this is usually a repair or replacement issue.
9. Listen for Fan Rattle or Unusual Noises
A small fan sound is normal, but a loud rattle, grinding sound, or scraping noise is not. Unusual noises may come from debris near the fan, a loose internal part, or damage after a fall.
Do this:
- Turn the appliance off.
- Unplug it.
- Let it cool.
- Remove the basket.
- Check for loose food particles.
- Look for broken plastic or metal pieces.
If the rattle continues, do not keep using it. A fan problem can affect airflow and heating.

10. Check Moisture or Water Damage
Moisture can cause electrical problems, display errors, or sudden shutdowns. This can happen if the basket was washed and returned while dripping wet, or if water entered the appliance housing.
Avoid:
- Putting the main unit in water
- Spraying cleaner into vents
- Pouring water inside
- Running the unit with wet electrical areas
- Storing it while damp
If you think water entered the control panel or electrical area, unplug the unit and do not use it until a qualified technician or the manufacturer checks it.
When Can You Reset an Air Fryer?
Some air fryers do not have a reset button. Others reset by unplugging the unit, waiting, and plugging it back in.
Try a simple reset only if there is no visible damage:
- Turn off the appliance.
- Unplug it.
- Wait 10–30 minutes.
- Reinsert the basket.
- Plug it into a working outlet.
- Start a short test cycle.
If it stops working again, the reset did not fix the real issue.
When You Should Repair or Replace It
You may need repair if the air fryer powers on but does not heat, shows repeated error codes, shuts off during every cycle, or has a damaged switch, sensor, fuse, or heating element.
Consider replacement if:
- Repair costs more than the unit
- The cord is damaged
- The plug overheats
- The basket or housing has a crack
- Electrical smell continues
- Error codes keep returning
- The appliance is old and out of warranty
If the air fryer is under warranty, contact the manufacturer before opening it. Opening the appliance may void the warranty and create an electrical risk.

Expert Advice
My practical advice is simple: only troubleshoot the safe external parts first. Check power, basket placement, vents, grease buildup, and settings. Do not open the body to test electrical components unless you are trained.
A small cleaning or reset issue is normal. A repeated heating failure, burning smell, error code, or damaged cord is not normal.
