Cosori Air Fryer Not Heating Up an-Ultimate Guide

Cosori Air Fryer Not Heating Up? I faced this issue for quite a time when I got a new air fryer from the market. I was exhausted because I did not know what to do in that case. This can be frustrating, but it’s usually an easy fix!

Here are some of the most common causes of this problem, and how to fix them. I have assessed the topic in full detail and got to reach a conclusion where I found out that my air fryer started working fine again.

Make sure there is oil in the tray

Just like any appliance, your air fryer needs to be primed before use. Before using it for the first time or after a long time without using it, be sure to check that there is at least 1/2 inch of oil in the tray before plugging it in.

That will make sure you don’t run into any trouble with cooking. If not, add enough oil so that you have at least 1/2 inch in your basket (the instructions usually recommend olive oil).

After adding your choice of oil, place a cooking thermometer in one of your baskets and set it to 400°F. Allow oil to heat up for about 10 minutes.

Clean the food catch dish

One reason why your air fryer might not be heating up is that there is a layer of old food stuck to its food catch dish.

To clean it, fill a bowl with hot water and put some dishwashing liquid in it. Once you do that, pour it into your air fryer’s food catch dish and then rotate it until you find that all of its sides are completely clean.

Since grease can get on food and catch dishes very easily, make sure to clean yours often. Also, keep in mind that you need to be extra cautious when cooking oils because they tend to produce more grease than others do.

Check if there is any blockage in the air tubes

Check that there are no blockages in any of your air tubes. If you see a blockage, clear it away with a pin. This will ensure that no unwanted debris is getting into your fryer.

Wipe any oil off of the bottom pan. Make sure there is no excess oil on your air fryer’s cooking surface.

Extra oils can interfere with your ability to heat up and could cause issues with preheating. If necessary, wipe down your pan thoroughly with an oil-soaked rag and then clean it off as much as possible before proceeding to step four.

Check for proper venting: Make sure all venting holes on top of your unit are unobstructed and open fully before using it again.

Remove the filter on top of the pan

Be sure to remove any buildup of grease on top of the pan. This will ensure a proper seal between your fryer and cooking basket, which is critical for effective heat conduction.

Cleaning it weekly will help keep your fryer working properly.

Use warm soapy water, or you can use air fryer cleaner made specifically for air fryers like ours. These products are great and leave very little residue.

Just be sure to rinse thoroughly with water afterward to prevent any build-up from occurring in future uses.


Check if the heating element is burnt out

If your air fryer has stopped heating, it might be that your heating element is burnt out. Even if it hasn’t burnt out completely, it can start smoking and smelling when food is in it for too long.

Turn off your machine and remove all food from inside before checking to see if there are any signs of damage to your heater.

If you think you can fix a broken heater, you’ll need to buy a new one as there are no spare parts available for Cosori air fryers.

You can purchase a similar-sized element (check with an electrician) or look at replacing your machine altogether.

Check if there are any loose wires

Possibly something as simple as a loose wire could be causing your fryer to not heat up. Check every wire and make sure they’re all firmly connected.

If you have a multi-plug, try moving it to another socket in case there’s an issue with yours.

It could be that you don’t have enough power going to your appliance. Alternatively, your circuit breaker might be turned off; turn it back on and try again. Just make sure nothing is blocking any air vents when you re-start it!

Check if anything gets stuck under the fan at the bottom (such as coins or hair clips)

If you’ve dropped a coin or hair clip into your fryer, they could be blocking airflow. It also may be stopping your fryer from working.

Remove anything that’s stuck under the fan at the bottom of your machine. If you think a foreign object has caused an electrical problem, stop using it right away and contact Cosori customer support.
