Smart air fryers are convenient — until something stops working. A dropped connection or an unresponsive app can be frustrating, especially when you just want dinner.
The good news is that most smart air fryer problems are minor, and the fixes are well known. This guide walks through the issues owners run into most often, with simple steps to solve them.
Problem 1: The Air Fryer Won’t Connect to Wi-Fi
This is by far the most common complaint — and most of the time, the cause is the same.
The likely reason: your network band. Almost all smart air fryers connect only to a 2.4 GHz Wi-Fi network, not a 5 GHz one. Many modern routers broadcast both. If your phone is on the 5 GHz band during setup, the air fryer cannot pair.
How to fix it:
- Connect your phone to the 2.4 GHz network during setup. On dual-band routers, this is often the network name without “5G” at the end.
- Move the air fryer closer to your router while pairing. A weak signal is a common cause of failure.
- Make sure your Wi-Fi password is simple — some devices struggle with special characters.
- Turn on Bluetooth and Location on your phone; many setup processes need them.
- If setup was interrupted, reset the air fryer (usually by holding a button for 5 to 10 seconds until the display blinks) and start again.
- Restart your router if other devices are also struggling.
If you are unsure whether your network is 2.4 GHz or 5 GHz, your internet provider can confirm it.

Problem 2: The Air Fryer Shows as “Offline” in the App
Sometimes the air fryer connects fine, but later appears offline in the app.
The most common reasons are simple: the air fryer is unplugged, or it is plugged into an outlet that has no power (for example, one controlled by a wall switch). Check the plug first.
If power is fine, try removing the air fryer from the app and adding it again. Re-pairing often restores the connection. Closing and reopening the app can also help.
Problem 3: The App Is Slow, Buggy, or Won’t Work
Sometimes the problem is not your air fryer or your network — it is the app itself.
If the app is sluggish, crashes, or fails to register the air fryer:
- Update the app. Outdated versions are a frequent cause of trouble.
- If updating does not help, uninstall and reinstall the app. This clears many software glitches.
- Restart your phone.
This is worth knowing before you buy: an unreliable app is a real possibility, which is exactly why you should never depend on the app alone — the manual controls on the machine are your backup.
Problem 4: It Won’t Start Cooking After Preheating
Many new owners think their air fryer is broken when it preheats but does not begin cooking on its own.
This is not a fault — it is a safety feature. For safety reasons, most smart air fryers will not start a cook cycle remotely or automatically, because that would leave food sitting in an unattended hot appliance. After preheating, you usually need to press the start button on the machine yourself.
In short: if your air fryer pauses after preheating, that is normal. It is waiting for you.
Problem 5: Beeping, Alerts, or an Unresponsive Screen
A few hardware-related issues come up often:
- Unexpected beeping or alerts can signal overheating or that the unit needs cleaning. Check the manual for what a specific alert means.
- A touchscreen that does not respond can sometimes be fixed by a simple reset — unplug the air fryer for a few minutes, then plug it back in. This clears many minor glitches.
- Inconsistent performance can be caused by dust or grease on the internal sensors. Wipe them gently with a soft, dry cloth.
Most of these are quick fixes, not signs of a broken machine.
When to Contact the Manufacturer
If you have worked through these steps and the problem continues, it is time to contact the brand’s customer support — especially if your air fryer is still under warranty.
Do not attempt to repair internal electronics yourself. Not only is it unsafe, it can also void your warranty. For a hardware fault, the manufacturer is your best route.
Preventing Problems Before They Start
A little maintenance keeps most issues away:
- Clean the basket and tray after every use. Built-up grease affects performance and can trigger alerts.
- Keep the sensors clear. Wipe them gently when you do a deeper clean.
- Keep the app updated. Updates fix bugs and improve stability.
- Do not overload the basket. Overcrowding leads to uneven cooking and extra strain on the machine.

The Bottom Line
Most smart air fryer problems fall into a few familiar categories — usually Wi-Fi setup, the app, or simple maintenance. The fixes take minutes, not expertise.
If your air fryer will not connect, check the 2.4 GHz network first. If the app misbehaves, update or reinstall it. If something seems broken, a reset often does the trick. And remember: the manual controls always have your back, even when the smart features do not.
