      If you see dark smoke coming from your Cosori Oven, immediately press the control knob to pause cooking and unplug the oven. This indicates that food is burning. Wait for the smoke to clear before opening the oven door.

      Nathan ParsonsAug 23, 2025
      It's normal for the Cosori Oven to produce some white smoke or steam during cooking. If it’s the first time using the oven, dust from packing may cause this. Also, excess oil or fatty foods may produce white smoke, so ensure the oven's interior is clean.

    Why does my thermometer show a different temperature than the Cosori CTO-R251 setting?

      Juan MillerAug 26, 2025
      Commonly used thermometers usually have low sensitivity and take over 10 minutes to measure the correct temperature. This will not affect cooking.

      Error code “E04” on your Cosori Oven indicates that the oven has been plugged into an incorrect power source, such as a 220–240V outlet. Unplug the oven and only use it with 120V, 60Hz outlets, like those in North America.

      White smoke or steam may be produced by the Cosori Oven during cooking, which is normal. During the first use, dust from the packing process may cause white smoke. Excess oil or fatty foods may also produce white smoke, so ensure the inside of the oven is cleaned properly and isn’t greasy.
