Decoding the 19-in-1 Oven: The "Preset vs. Function" Secret You Need to Know

It’s marketed as the “kitchen superhero”—a single, 32-quart appliance that promises to replace 19 of your other gadgets. And for many, the promise holds true. The primary motivation for upgrading to a massive “all-in-one” oven, like the Beelicious BAF-802, is sheer capacity.

Users are graduating. They are tired of “enormous let downs” from smaller air fryers that “could only handle a tiny cornish game hen.” They want a machine where they can, as one user triumphantly reported, “rotisserie an 8 lb. chicken… and it has been amazing!”

This is the central appeal: a “true mini oven” (bmbranno) with 1800W of power, four cooking layers, and the 32QT capacity to fit a 13-inch pizza or a 10lb turkey. It’s a “combination oven” (Felicia L. Jones) that can, for a 1-2 person household, effectively replace their “humongous full-size gas oven” (Kai Starr).

But this superhero-level power comes with a trade-off, a “kryptonite” that the instruction manual fails to mention. As countless users have discovered, the controls are a “confusing,” “strange,” and “not very sensitive” puzzle.

This is the secret to mastering your new oven.

The #1 Source of Confusion: “Presets Are Not Functions”

The biggest hurdle for new owners is the “19-in-1” digital touch screen. User Felicia L. Jones articulated this frustration perfectly: “The next thing that I absolutely hate is the pre-sets mixed in with functions… A pre-set is not a function.“

This is the key. The machine’s marketing boasts 19+ presets, creating a cluttered, confusing interface. You’ll see buttons for “Chips” (which, as user Kai Starr points out, just means “Fries” for US users), “Wings,” “Cookies,” and “Pizza.”

As Felicia notes, these are “just redundant.”

To master this oven, you must ignore the 19 presets and learn to use the 5 real functions:
1. BAKE (Standard Convection)
2. AIR FRY (High-Speed Convection)
3. ROTISSERIE (Motorized Spit)
4. DEHYDRATE / PROOF (Low-Temperature Holding, 90°F+)
5. BROIL (Top-Down Heat)

One user brilliantly discovered this: “I saw someone ask if you could make yogurt… The person answering obviously thought because it didn’t have a pre-set for yogurt that it couldn’t do it. But it can in the proof mode, temp is low enough and time can go long enough.”

This is the secret. The “Proof” function (which operates at 90°F) is the tool. The “Yogurt” preset is just a label. By understanding the core functions, you unlock the machine’s true potential, like its “innovative dual cook function,” which allows you to combine two real functions (e.g., Bake then Broil) to create complex recipes.

Decoding the “Strange” Controls and That Loud Beep

The second frustration is the interface itself. It’s not intuitive, and the manual is little help.

• The “Strange” Scrolling: As user Kai Starr explains, “you can’t just push one to select it… You have to ‘scroll’ through the presets… using the + and - buttons.” This is a common, but confusing, control scheme. You must use the “mode” or “temp/time” buttons to activate a setting, then use the +/- buttons to change it.
• The “Finicky” Buttons: User DPM notes the “touch screen is not very sensitive,” and Watts Up complains about the “capacitive buttons, and not actual buttons.” You must learn the feel of the panel, using a flat, firm press rather than a quick tap.
• The “Insanely Loud” Beep: The most visceral complaint comes from Watts Up: “the BEEP… is about 10x louder than it needs to be.” “I don’t want to wake up my wife and kids.” This appears to be a non-adjustable “feature” and a significant design flaw for many users.

The Real-World Performance: What Users Actually Found

Once you get past the controls, how does it perform? The user consensus is fascinating: it’s a “fantastic oven” that might not be the best air fryer.

User Robert states it plainly: “As an air fryer it doesn’t cut the mustard. Have two others that blow this away… But as an oven this thing shines.”

This makes perfect sense. The 1800W of power and “360° hot airflow” in a massive 32QT cavity create a phenomenal convection oven. It arrived hard as a rock reported, “I baked a fantastic cake. It rose higher than any cake I’ve ever baked.” This is its true strength. It’s not just a big air fryer; it’s a “true mini oven.”

This is also why the Rotisserie is the star feature. The large interior, which was the reason to buy, allows it to “rotisserie an 8 lb. chicken… Omgosh, it was perfect!!!” (bmbranno). This is a feat impossible in smaller fryers.

The Quirks You Have to Live With

Finally, users reported a few “quirks” that are part of the trade-off for this capacity and price.

1. The “Very Hard to Clean” Tray: DPM warns that if “you get anything on the drip tray or cooking tray, it bakes on and VERY hard to clean.” The universal solution? “I line mine with foil and solved this problem.”
2. Uneven Multi-Level Cooking: The “4 layers even cooking” claim is debatable. DPM found “dual level cooking is not perfect. Upper level done first and lower level takes more time.” This is a standard physics problem in all ovens, but one to be aware of.
3. The “Cool” Exterior: On the plus side, multiple users praise the double glass door, noting the “exterior of the oven is not hot to the touch” (Felicia) and “stays much cooler on the outside than any brand I have tried” (DPM).

Conclusion: A Superhero That Needs a “Pro” Handler

The Beelicious BAF-802 is a perfect case study in the “kitchen superhero” trade-off. It does deliver on its main promise: massive 32QT capacity. It successfully graduates users from small, disappointing fryers to a “true mini oven” that can rotisserie a full-size chicken and replace a full-size range for daily tasks.

In return, it demands that you become the “pro.” You must learn to ignore its confusing “19-in-1” preset marketing and master its 5 core functions. You must accept its “insanely loud” beep and finicky touch panel. And you must line your drip tray with foil.

If you can accept these trade-offs, you get a powerful, versatile, and high-capacity oven that, as bmbranno put it, is “perfect in every way.”
