Is your Cosori air fryer sensor not working? If your fryer isn’t responding like it used to, it can be frustrating and stop you from enjoying quick, tasty meals.
You rely on your air fryer to make cooking easier and faster, so when the sensor fails, it feels like your kitchen helper lets you down. But don’t worry—there are simple steps you can take to fix this problem and get your air fryer back to perfect cooking.
Keep reading to find out exactly why your sensor might be malfunctioning and how you can solve it fast.
How the Cosori Air Fryer Sensor Works
The Cosori air fryer sensor controls heat during cooking. It checks the air temperature and sends signals to the control board. The board then adjusts the heat to keep cooking even. When the sensor works right, food turns golden and crisp. If it fails, meals may come out burnt or undercooked. I’ve noticed this myself when the sensor wasn’t reading well.
Most models use a thermistor sensor, which reacts to temperature changes fast. It helps the air fryer stay steady, even when you open the basket. The sensor also prevents overheating by lowering heat when needed.
Common Cosori Air Fryer Sensor Issues and Performance Problems
Common sensor issues with the Cosori Air Fryer can affect its performance. Sensors help control cooking time and temperature. When these sensors fail, the air fryer may not cook food properly. Understanding common sensor problems helps in quick troubleshooting. This saves time and keeps your appliance working well.
Signs Of Sensor Malfunction
The air fryer may stop heating or cook unevenly. It might show error messages on the display. Sometimes, the screen freezes or does not respond to touch. Food might come out undercooked or burnt. The appliance could shut down suddenly during use. These signs indicate sensor problems in the air fryer.
Cosori Sensor Error Codes and What They Mean
Your Cosori air fryer shows error codes when something isn’t working right. These codes help you spot and fix the issue fast.
E1 – Sensor Not Connected: The sensor wire may be loose or broken. Unplug the fryer and check the connection.

Using the wrong power supply can harm sensor functions. Physical damage from dropping the air fryer can break sensors. Regular cleaning and careful use help prevent these issues.

Basic Troubleshooting Steps to Fix Cosori Air Fryer Sensor Not Working
Basic troubleshooting helps fix many common issues quickly. This is true for the Cosori Air Fryer sensor not working. Start with simple checks before considering repairs or replacements. These steps save time and effort.
1. Power Cycle Your Cosori Air Fryer to Reset the Sensor
Turn off the air fryer and unplug it from the wall. Wait for about 1 minute. Plug it back in and turn it on. This resets the system and can clear minor errors. It often restores sensor function without extra work.

Use a soft cloth slightly dampened with water to wipe the sensor. Avoid harsh chemicals or abrasive materials. Dirt and grease build-up can cause sensor errors. Cleaning keeps the sensor clear and improves accuracy.
Step-by-Step Sensor Cleaning Guide:
Keeping your Cosori air fryer sensor clean helps it work better. A clean sensor reads heat correctly and keeps your food crisp.
Unplug the Air Fryer: Always unplug it first and let it cool down. Cleaning while it’s hot or plugged in can cause damage.
Remove the Basket and Tray: Take out both parts to reach the sensor area. This gives you better access and keeps parts safe from scratches.
Use a Soft, Damp Cloth: Gently wipe the sensor using a soft, damp cloth. Avoid harsh cleaners or too much water to prevent damage.
Clean Around the Sensor Base: Check for grease or crumbs near the sensor. Clean these areas carefully to avoid buildup that affects readings.
Dry the Area Properly: Use a dry cloth or paper towel to remove moisture. Make sure it’s fully dry before plugging the air fryer back in.
Reassemble and Test: Place the basket and tray back in. Turn on the fryer and test if it heats evenly again.
