The Chefman 20L air fryer oven combines hot-air cooking technology with a compact, convenient countertop oven and a wide range of functions. The standout feature is the built-in probe thermometer, which tracks the internal temperature of your food as it cooks so every dish comes out exactly the way you like it.

Mute alarm (silence the beeps if you want), flip reminder, and rest indicator (keep warm) to help you along

Internal food temperature alert when using the probe – less risk of undercooked food

4. How to use

1. Plug it in and select the right preset (for example Air Fry, Bake…).

2. Insert the probe thermometer into the food (meat, fish…) to the required depth.

3. If you want your own temperature, choose Probe Mode and set the temperature + time.

4. Press Start → once the target temperature is reached, the oven shuts off or signals you.

5. Use oven mitts to take the food out.

6. Remove the probe and clean the cooking chamber and accessories once the oven has cooled.

5. Notes

Use heat-resistant mitts when handling the probe and trays while they are still hot.

Make sure the probe is seated firmly, and keep the tip from touching the bottom of the chamber.

Do not use metal utensils, to avoid scratching the nonstick coating.

Clean the probe carefully; do not submerge the entire sensor head.

Check the chamber regularly and clear out food crumbs so they do not affect the fan or electrical safety.
