Instant air fryer temperature settings can be switched between Celsius and Fahrenheit with a simple button combination. If you want to know how to change instant air fryer from celsius to fahrenheit, the process takes less than a minute on most models. You do not need a manual or a factory reset. Just a few button presses and your display will show the unit you prefer.
This guide covers the exact steps for the most common Instant Pot air fryer models. It also explains what to do if your buttons do not respond the way you expect.
Why Your Instant Air Fryer Shows Celsius
Instant air fryers ship with different default temperature units depending on where they are sold. Units made for the United States and Canada usually default to Fahrenheit. Units sold in Europe, Asia, and Australia typically default to Celsius.
If you bought your air fryer online or moved to a new country, the display may show Celsius even though you think in Fahrenheit. Some users also hit the wrong button by accident and switch the unit without noticing.
The good news is that the setting is not locked. You can flip between Celsius and Fahrenheit at any time. The change applies to the display only. It does not affect cooking performance or the actual heat inside the basket.
How To Change Instant Air Fryer From Celsius To Fahrenheit
The method varies slightly by model. Below are the steps for the most popular Instant air fryer lines. Find the one that matches your unit.
Instant Vortex Plus And Vortex Plus 6-In-1
This is the most common model family. The temperature unit toggle is built into the dial and the Temp button.
- Plug in the air fryer and let it sit on the standby screen.
- Press and hold the Temp button for about 3 seconds.
- While holding Temp, turn the dial one click in either direction.
- Watch the display. It will flip from C to F or F to C.
- Release the Temp button. The new unit stays saved.
On some newer Vortex Plus units, you only need to press and hold the Temp button. The display switches on its own after 3 to 5 seconds. Try that first before adding the dial turn.
Instant Vortex 4-In-1 And 5.7Qt Models
These models use a slightly different combo. The Time and Temp buttons work together.
- Make sure the air fryer is not in cooking mode.
- Press and hold both the Time and Temp buttons at the same time.
- Hold for 3 to 5 seconds.
- The display will switch between Celsius and Fahrenheit.
- Let go of both buttons once the new unit appears.
If nothing happens, unplug the unit for 30 seconds and try again. A quick power cycle clears minor software glitches.
Instant Pot Duo Crisp And Air Fryer Lid
The Duo Crisp uses the air fryer lid with its own control panel. The unit change happens on the lid, not the main pot base.
- Attach the air fryer lid and plug it in.
- Press the Temp button once to enter temperature mode.
- Press and hold the Temp button for 3 seconds.
- Use the plus or minus buttons to toggle the unit.
- Press Start to save the setting.
On the standalone Instant Air Fryer Lid, the same Temp button hold works. You will see a small C or F next to the numbers.
Instant Omni And Omni Plus Toaster Oven Air Fryers
These larger units have a dial and a dedicated Temp button. The method is close to the Vortex Plus.
- Turn the unit on so the display is active.
- Press and hold the Temp button.
- Turn the dial one notch while holding.
- The display switches units.
- Release the button to lock it in.
Some Omni models require you to hold Temp and the dial press together. If the first method fails, try pressing the dial in like a button while holding Temp.
What To Do If The Button Combo Does Not Work
Not every unit responds the same way. Try these fixes in order.
- Unplug the air fryer for one full minute, then plug it back in.
- Make sure the unit is not mid-cook or in preheat mode.
- Check that the control panel is clean and dry. Sticky residue can block button presses.
- Hold the buttons longer. Some units need a full 5 seconds.
- Confirm your exact model number on the label under the unit.
If you still cannot switch the unit, your model may not support a manual toggle. A few older or region-locked models only show one unit. In that case, you can convert temperatures yourself.
Quick Celsius To Fahrenheit Conversion
Use this formula if your display is stuck on Celsius:
- Multiply the Celsius number by 1.8.
- Add 32 to the result.
For example, 180C equals 356F. Most recipes round this to 350F or 360F. Here are common air fryer temps:
- 160C equals 320F
- 170C equals 338F
- 180C equals 356F
- 190C equals 374F
- 200C equals 392F
Keep this list handy if your model will not switch. It saves you from doing math every time you cook.
Tips To Keep Your Setting Saved
Once you switch to Fahrenheit, the air fryer should remember it. The setting is stored in memory, even after you unplug the unit.
But a few things can reset it:
- A full factory reset from the settings menu
- A firmware update on smart models
- Pressing the button combo again by accident
If your unit keeps flipping back to Celsius on its own, contact Instant support. That is not normal behavior and may point to a control panel issue.
On smart models like the Instant Vortex Plus with ClearCook and Wi-Fi, you can also check the unit setting inside the Instant Brands app. Open the device settings and look for Temperature Unit. Change it there and the air fryer will update on its next connection.
Final Thoughts On Switching Temperature Units
Changing your Instant air fryer from Celsius to Fahrenheit is a quick button hold on almost every model. The Temp button is the key on most units. On a few models, you pair it with the dial or the Time button.
If the combo fails, unplug the unit, clean the panel, and try again with a longer hold. And if your model simply does not support the switch, the conversion list above keeps your cooking on track.
Now you can follow any recipe in Fahrenheit without guessing. Set your temp, hit start, and get back to cooking.
