Question 1

trying to connect my pro iii to the app for smart recipes but it won't find the device

Accepted Answer

DIAGNOSIS The most common hiccup is a mismatch between your phone's Wi-Fi network and the air fryer's setup requirements. The fryer needs a 2.4 GHz Wi-Fi network (not 5 GHz) and can struggle with networks that have special characters in the password or SSID. FIX 1) On your phone, forget any 5 GHz network with the same name and connect only to the 2.4 GHz band. 2) In the VeSync app, during setup, make sure you grant location permissions—it needs this to find Bluetooth/Wi-Fi devices. 3) Keep your phone very close to the air fryer (within 3 feet) during the whole process. IF THAT DIDN'T WORK Reset the air fryer's Wi-Fi module. With the unit on, press and hold the Temp/Time and Power buttons together for 5 seconds until the Wi-Fi icon flashes. Then try the setup process from scratch. HEADS UP The smart features are handy, but the air fryer works perfectly fine in manual mode if you decide the app isn't worth the hassle.

Question 2

cosori makes a loud rattling or grinding noise when the fan is on, sounds bad

Accepted Answer

DIAGNOSIS Something is interfering with the fan blade. It's either a piece of loose food/debris caught in there, or the fan blade itself has become unbalanced or loose on its shaft. FIX 1) Unplug and cool. 2) Remove the basket and pot. 3) Look into the main chamber and use a flashlight to inspect the fan blade near the heating element. Use long tweezers or needle-nose pliers to carefully remove any visible debris. 4) Gently try to wiggle the fan blade—it should not move side-to-side. IF THAT DIDN'T WORK If the noise persists and the blade seems loose, or if you see no debris, the fan motor assembly is likely faulty. This is a repair for Cosori technicians. HEADS UP Always let large crumbs fall into the basket, not the main unit. Avoid shaking the basket directly over the heating element chamber.

Question 3

the nonstick coating on my basket is peeling and flaking off after a few months, is that safe?

Accepted Answer

DIAGNOSIS That's damaged non-stick coating. It's not safe to cook with if it's flaking into your food, and it's often caused by using metal utensils, abrasive scrubbers, or harsh dishwasher detergents. FIX Stop using it immediately. Contact Cosori customer support directly with clear photos of the damage. This is a known issue with some batches, and they are typically very responsive, often sending a replacement basket under warranty. IF THAT DIDN'T WORK If they don't provide a replacement, you can purchase an official Cosori-branded replacement basket online. Do not use a generic one, as the fit and safety may be compromised. HEADS UP To preserve the new coating, hand-wash with a soft sponge and mild detergent. Never use steel wool or put it in a dishwasher, even if it says it's dishwasher-safe—the harsh chemicals and heat accelerate wear.

Question 4

my fries are coming out soggy not crispy in the new cosori, am i doing something wrong?

Accepted Answer

DIAGNOSIS This is almost always a crowding issue. You're probably overloading the basket, which blocks the rapid air circulation that's essential for crisping. FIX 1) For best results, cook in multiple smaller batches. 2) Make sure your food is completely dry (pat potatoes or tofu dry). 3) Toss items in just a teaspoon or two of oil—too much will steam them. 4) Shake the basket vigorously halfway through, don't just give it a gentle stir. IF THAT DIDN'T WORK Check that you're not using the "reheat" or "keep warm" function by mistake. For fries, use the "Air Fry" function, set to at least 400°F, and always preheat the unit until it beeps. HEADS UP The non-stick coating on the basket can actually hinder crisping if you don't use a little oil. A light coating helps achieve that golden texture.

Question 5

cosori pro iii screen says 'E1' or 'E2' when i try to start it, what does that mean?

Accepted Answer

DIAGNOSIS E1 means the temperature sensor is reading an error (likely an open circuit), and E2 means it's reading a short circuit. In plain terms, the machine thinks the sensor that tells it how hot it is isn't working right. FIX First, try the hard reset: unplug, hold the power button for 15 seconds, wait a minute, plug back in. If the code clears, you're good. If E1/E2 returns, the sensor connection inside is probably loose or faulty. IF THAT DIDN'T WORK There's no safe user repair for a faulty sensor. You'll need to reach out to Cosori support with your error code. They're good about these known issues and will likely offer a replacement. HEADS UP Avoid slamming the cooking pot into place, as that can jar the internal sensor connections over time.

Question 6

air fryer shuts off by itself mid-cycle with a burning smell, no error code

Accepted Answer

DIAGNOSIS That's an automatic overheat protection trip. The fan or heating element area is probably clogged with accumulated grease and crumbs, causing poor airflow and excessive heat buildup. FIX 1) Unplug and let it cool for at least an hour. 2) Remove the basket and the inner cooking pot. 3) Flip the main unit upside down over a trash can and use a can of compressed air to blow out the vents and the heating element chamber. You'll be surprised at what comes out. IF THAT DIDN'T WORK If it still trips, the thermal fuse or sensor might be damaged from repeated overheating. You'll need to contact Cosori. HEADS UP Never cover the vents on the top or back during use. Give it at least 5 inches of clearance on all sides.

Question 7

the basket on my 5.8qt cosori pro is stuck and i can't get it out, handle feels jammed

Accepted Answer

DIAGNOSIS Food debris or grease has likely hardened in the basket release mechanism's track, jamming the latch. FIX Don't force it. 1) Unplug the unit and let it cool completely. 2) Lay a hot, damp cloth over the area where the basket handle meets the main body for 5 minutes to soften the gunk. 3) While holding the release button down, gently wiggle the basket side-to-side as you pull. It should come free. IF THAT DIDN'T WORK You may need to access the latch. Remove the four screws on the underside of the handle cover (use a small Phillips head), lift the cover, and clean the latch mechanism directly with a soft brush and a little warm, soapy water. HEADS UP Always clean the basket release area and the corresponding slot in the main unit after each use to prevent this.

Question 8

my cosori pro iii just flashes all the lights and beeps constantly when i plug it in, won't let me do anything

Accepted Answer

DIAGNOSIS That's a classic control board error state. It's usually triggered by a momentary power surge or a glitch during the last use. FIX You need to perform a hard reset to clear the memory. 1) Unplug the air fryer from the wall outlet. 2) Press and hold the power button down for 15 full seconds. 3) Wait 60 seconds, then plug it back in. This should clear the error and the lights will return to normal. IF THAT DIDN'T WORK If it's still flashing, the internal fuse might have blown. You'll need to contact Cosori support for a replacement fuse or unit. HEADS UP Always plug your air fryer directly into a wall outlet, not a power strip, to prevent these voltage-related resets.
