Cosori Air Fryer Keeps Stopping — Fix

What Does This Error Mean?

A Cosori that stops mid-cook is almost always pausing because the basket was opened and not restarted, or overheating protection has triggered. When the basket is removed and reinserted, press Start again — Cosori models pause automatically when the basket is opened. Also ensure the air fryer has at least 15 cm of clear space on all sides.

Control board fault

How to Fix It

Press Start after reinserting the basket.

Cosori air fryers pause cooking automatically when the basket is removed for shaking or checking food. Reinserting the basket does not automatically resume — you must press Start again.
Ensure 15 cm of clear space on all sides of the unit.

Blocking the rear vent causes overheating and automatic shutdown. Do not place the air fryer against a wall, under a cabinet, or on a cloth surface.
Reduce the temperature when cooking oily foods.

Cooking very oily foods at 200°C for more than 25 minutes can trigger the thermal cutoff. Reduce the temperature by 10°C — cooking time will be slightly longer but the unit will stay within thermal limits.
Check the auto-shutoff timer setting.

The Cosori will automatically stop when the set cook time reaches zero. Confirm the timer was set correctly before starting the cook cycle.
Clean the air vents on the rear and top of the unit.

Grease and food particles can block the vents over time, reducing airflow. Wipe vent slots with a dry cloth or soft brush. Do not use water on the vents.

When to Call a Professional

If the Cosori stops within seconds of starting with no display error and the basket is correctly seated, the control board or power supply may be failing. Contact Cosori support.

Frequently Asked Questions

Why does my Cosori air fryer stop after a few minutes?

If it stops after a very short time without completing the cook, overheating protection or a control board fault is likely. Ensure ventilation clearance, reduce the temperature, and test again. If it persists, contact Cosori support.

Does the Cosori air fryer pause when you open the basket?

Yes, by design. Most Cosori models automatically pause the timer when the basket is removed. After shaking the food and reinserting the basket, press the Start button to resume cooking.
