Your Cosori TurboBlaze Air Fryer won’t turn on and the display is completely blank. This is a common and almost always fixable issue. The solution almost always comes down to one of two simple things: a loose power connection or the basket not being fully inserted. We’ll walk you through checking both, then cover what to do if those quick fixes don’t work.
Quick Answer: First, ensure the power cord is firmly plugged into both the air fryer and your 120V wall outlet. Then, push the basket all the way into the unit until you hear a distinct click, as the appliance will not power on if the basket isn’t fully seated.
Why Your Cosori Air Fryer Has No Power
A blank display and no response to button presses mean the appliance isn’t receiving power to its main board. For the Cosori TurboBlaze, this is almost never a sign of a major internal failure. The safety design intentionally prevents operation if key components aren’t correctly connected.
Check the Power Connection
This is the most frequent culprit. The power cord has two connection points: where it plugs into the back of the air fryer body and where it plugs into your wall outlet. Both need to be secure.
- Unplug the cord from the wall outlet first.
- Check the connection at the back of the air fryer. The plug should be pushed completely into the appliance’s socket. Wiggle it to ensure it’s not loose.
- Plug the cord firmly into a 120V, 60Hz wall outlet. Do not use an extension cord or power strip, as these can introduce connection issues. The unit is designed for 120V operation only; using a 220–240V outlet will cause an E04 error code.
- Listen for a faint beep and look for the display to illuminate.
If there’s still no power, the issue could be with the outlet or the cord itself.
Make Sure the Basket Is Seated
The Cosori TurboBlaze has an important safety interlock: it will not turn on if the cooking basket isn’t correctly installed. This prevents the heating element from operating with the basket removed.
- Remove the basket by its handle.
- Check that the crisper plate inside is properly seated. It should lie flat and not be crooked.
- Align the basket with the guides inside the air fryer chamber.
- Push the basket in firmly and steadily until you hear and feel a definitive click. The handle should be flush with the front of the appliance.
After clicking the basket into place, press the power button. The display should now light up. If the basket is overfilled with food, it may not seat correctly, preventing the unit from powering on.
What to Do If It Still Won’t Start
If you’ve confirmed a solid power connection and a properly clicked-in basket but the unit remains dead, the problem lies further back in the power pathway. You’ll need to systematically check the cord and the outlet.
Inspect the Power Cord
Visually examine the entire length of the power cord for any obvious damage. Look for cuts, kinks, melted sections, or fraying near the plugs. Gently bend the cord near the ends to check for internal breaks. If you find any damage, do not use the appliance. You will need to contact Customer Support for a replacement cord.
Check Your Outlet
Your wall outlet might be the problem. To test it:
- Unplug the air fryer.
- Plug a different, small appliance (like a lamp or phone charger) into the same outlet to see if it works.
- Try plugging the air fryer into a different, known-working 120V outlet in another room.
If the air fryer works in a different outlet, the first outlet may have a tripped GFCI (common in kitchens), a blown fuse, or a faulty circuit. Reset your GFCI outlet or check your home’s circuit breaker panel. If the air fryer doesn’t work in any outlet, the issue is with the appliance.
When to Contact Support
If you’ve methodically checked all of the above—power cord, multiple outlets, and basket seating—and the unit still shows no signs of life, it’s time to reach out for professional help. Similarly, if the display shows an error code like E01, E02, or E04, you should contact Customer Support. These codes indicate an internal circuit or voltage issue that you cannot safely fix at home.

Frequently Asked Questions
My Cosori TurboBlaze was working and now it’s dead. What happened?
The most likely cause is that the power cord became slightly unplugged from the wall or the appliance during use, or the basket was bumped and unseated just enough to break the safety connection. Always check these two connections first after any sudden loss of power.
Why does the Cosori basket have to click for it to turn on?
This is a critical safety feature. The click confirms the basket is fully inserted, which activates an internal switch. This prevents the high-temperature heating element and fan from operating while the basket is out, protecting you from burns and preventing the unit from overheating.
Can I use an extension cord with my Cosori air fryer?
No. Safety instructions advise against using extension cords or power strips. These can overheat under the air fryer’s sustained 1750-watt power draw, creating a fire hazard. Always plug the unit directly into a dedicated 120V wall outlet.
The display lit up but then went off and won’t come back on. Is it broken?
Not necessarily. If you saw a brief flash or an error code before it shut off, it may have entered a protection mode. Unplug the Cosori TurboBlaze from the wall for 10 full minutes to allow it to reset completely. After plugging it back in and ensuring the basket is clicked in, try turning it on again.
I see an E04 error code on my Cosori. What does that mean?
An E04 error means the air fryer has detected it is plugged into a 220–240V outlet. It is designed only for 120V, 60Hz power. You must immediately turn off and unplug it. Using it on the wrong voltage can permanently damage the unit. You’ll need to find a proper 120V outlet to use it.
I hear a faint hum or see lights, but the buttons don’t work. What’s wrong?
This could indicate a control panel issue. First, perform a full reset by unplugging the unit for 10 minutes. If the problem persists, there may be a fault in the main control board. At this point, you should contact Customer Support for further diagnosis, as internal repairs are not user-serviceable.
