Common Cosori Air Fryer Error Codes and Solutions

Cosori air fryers, like many modern appliances, use error codes to communicate specific issues. Understanding these codes can help you quickly diagnose and resolve problems. Here are some common Cosori air fryer error codes and how to fix them:
- E1 Error: This error typically indicates an open circuit or a problem with the temperature sensor.
- Solution: First, try resetting the air fryer by unplugging it for a few minutes and then plugging it back in. If the error persists, the temperature sensor may need to be replaced. Contact Cosori support for assistance or consult a qualified appliance repair technician.
- E2 Error: This error usually points to a short circuit.
- Solution: Similar to the E1 error, start by resetting the air fryer. If the error continues, there may be a more significant electrical issue. Do not attempt to repair the air fryer yourself; instead, contact Cosori customer support or a professional repair service.
- E3 Error: An E3 error might suggest the appliance is overheating.
- Solution: Ensure that the air fryer is placed on a flat, stable surface with adequate ventilation. Make sure that the air vents are not blocked. Allow the unit to cool down completely before attempting to use it again. If the error persists, it could indicate a faulty thermostat.
- E5 Error: This error code can relate to a communication problem between the display panel and the control board.
- Solution: Try resetting the air fryer first. If that doesn’t work, this issue typically requires professional repair, as it involves the internal electronics of the device.
- No Error Code but the Air Fryer Won’t Turn On: Several reasons can cause this, such as a loose power cord, a faulty outlet, or an issue with the air fryer’s internal components.
- Solution: Check that the power cord is securely plugged into both the air fryer and the outlet. Test the outlet with another device to ensure it’s working. If the air fryer still doesn’t turn on, it may require professional inspection and repair.
Troubleshooting Air Fryer Power Issues
Power-related problems can be frustrating, but they’re often easy to resolve with a few simple checks. Here’s how to troubleshoot power issues with your Cosori air fryer:
- Check the Power Cord and Outlet: Ensure the power cord is securely plugged into the air fryer and the electrical outlet. Test the outlet with another appliance to confirm it’s working correctly. Sometimes, the outlet may be faulty or tripped, preventing the air fryer from receiving power.
- Reset the Air Fryer: Unplug the air fryer from the outlet, wait a few minutes, and then plug it back in. This can sometimes reset the internal systems and resolve minor electrical glitches.
- Inspect the Fuse or Circuit Breaker: If the air fryer still doesn’t turn on, check your home’s fuse box or circuit breaker panel. A tripped breaker or blown fuse can cut off power to the outlet. Reset the breaker or replace the fuse if necessary.
- Avoid Overloading the Circuit: Air fryers can draw a significant amount of power. Avoid plugging the air fryer into an outlet that is already powering multiple high-wattage appliances. Overloading the circuit can cause power outages and potentially damage the air fryer.
- Professional Inspection: If none of these steps work, there may be an internal electrical issue with the air fryer. In this case, it’s best to contact Cosori customer support or a qualified appliance repair technician for further assistance.
Addressing Cooking Problems

If your food isn’t cooking properly in the Cosori air fryer, it could be due to several factors. Here’s how to troubleshoot common cooking issues:
- Uneven Cooking: Uneven cooking often occurs when food is overcrowded in the air fryer basket. Make sure to arrange food in a single layer, leaving space for air to circulate. For larger batches, cook in multiple rounds. Shaking or flipping the food halfway through the cooking process can also promote even browning and crisping.
- Food Not Crispy Enough: Achieving the desired level of crispiness requires proper technique. Ensure that the food is dry before placing it in the air fryer, as excess moisture can prevent browning. Tossing the food with a small amount of oil can also enhance crispiness. Increase the cooking time or temperature slightly if needed.
- Food is Overcooked or Burnt: Overcooking can happen if the temperature is set too high or the cooking time is too long. Lower the temperature or reduce the cooking time, and check the food periodically to prevent burning. Using the recommended cooking settings for specific recipes can help avoid overcooking.
- Smoky Air Fryer: If your Cosori air fryer is producing excessive smoke, it could be due to high-fat foods splattering and burning. Ensure that the basket and drip tray are clean before use. Cooking high-fat foods in smaller batches can also reduce smoke. If the problem persists, add a small amount of water to the bottom of the drip tray to catch drippings and prevent burning.
- Unpleasant Odors: Unusual smells can occur if the air fryer is not properly cleaned. Food particles and grease can accumulate and burn, causing unpleasant odors. Clean the basket, drip tray, and interior of the air fryer regularly with warm, soapy water. For stubborn odors, try running the air fryer with a slice of lemon or a tablespoon of vinegar in a cup of water.
Dealing with Unusual Noises
Strange sounds coming from your Cosori air fryer can be concerning. Here’s how to identify and address unusual noises:
- Rattling or Vibrating: Rattling or vibrating noises are often caused by loose components or the air fryer sitting on an uneven surface. Ensure that all parts of the air fryer are properly assembled and secured. Place the air fryer on a flat, stable surface to reduce vibrations.
- Buzzing or Humming: A buzzing or humming noise could indicate a problem with the fan motor. Check if the fan is obstructed by food debris or other objects. Clean the fan area and ensure it can spin freely. If the noise persists, the fan motor may need to be replaced.
- Grinding: Grinding noises can suggest that there is something caught in the fan or that the motor bearings are wearing out. Inspect the fan and remove any obstructions. If the noise continues, the motor may need professional repair or replacement.
- Popping or Cracking: These noises are often normal and can be caused by the heating element expanding and contracting during use. However, if the noises are excessively loud or accompanied by other issues, it’s best to investigate further.
- Contact Customer Support: If you are unsure about the cause of the noise or how to fix it, contact Cosori customer support for assistance. They can provide specific troubleshooting advice or recommend professional repair services if needed.
