Where to get real advice for this machine

Almost everything that changes a cooking answer is a property of the architecture rather than the badge. This is a dual-basket air fryer, and the Dual-basket air fryer page carries the cooking guidance that actually applies to it.

Each drawer behaves as a single basket machine, so times and temperatures transfer across unchanged. What changes is the planning: two foods with different times must be started at different moments, and the synchronise function most of these machines offer does that by delaying the shorter cook rather than by speeding it up. Total capacity is genuinely double, but each individual drawer is often slightly smaller than a comparable single-basket machine.

Does it genuinely air-fry?

Genuine air frying

Assessed against the criteria on the same basis as the AF400UK, with which it shares its architecture and its manual's description of it: two self-contained drawers, each with a separate element and fan above a perforated crisper plate that elevates the food. Fast air and air reaching every surface are met by construction.

  • Air moves fast, not just around
  • Air reaches every surface of the food
  • Recovers temperature quickly after loading
  • Fat and moisture drain away
  • Reaches genuine browning temperatures

What we know about this machine

Read from Ninja Foodi Dual Zone Air Fryer AF300UK — Instructions (PDF) (revision AF300UK_Series_30_IB_MP_Mv2_200414), retrieved on 2026-08-13.

It is rated at 2470 W, which is toward the top of the domestic range and means it recovers temperature quickly after cold food goes in. It has 2 independent drawers, so two foods can cook at different temperatures at once — which buys variety rather than volume. On preheating: comes up to temperature quickly.

The figures above are the manufacturer’s. What they mean for cooking is AirfryerHQ’s reading of them, not a measurement — nobody here has run this machine.

10 figures we could not establish

Each of these says WHY it is missing. “Not recorded by the sources consulted” means the manufacturer does not publish it in the document we read — not that nobody looked, and not that the figure does not exist.

Advertised capacity
Not recorded by the sources consulted — The manual's technical specification panel states voltage and wattage only. The retailer that published this copy titles the product 7.6L, but a retailer's product title is not a manufacturer specification and is not recorded as one.

Error codes and display states

Only what this manufacturer publishes, and only for this manufacturer. A code means whatever the firmware author decided it means, and reading one across from another brand is the commonest way to misdiagnose a fault.

AirfryerHQ does not hold this code for this manufacturer. That is a statement about this catalogue and not about your appliance: most manufacturers publish no code table at all, and a code's meaning is specific to the firmware that produced it. Do not read a meaning across from another brand — check your own manual, and contact the manufacturer if it is not in there.

Replaceable parts

Read from this machine’s own documentation. Fit is stated only for the models a manufacturer names — it is never inferred from advertised capacity.

  • Crisper plate

    Crisper plate for the Ninja AF300UK

    The perforated plate that raises food off the drawer floor so air reaches underneath. The AF300UK takes two, and they are a different part from the AF400UK's.

    You can fit this yourself: Lift out, drop in. Order by the reference above. Cooking without a crisper plate is possible and is not air frying: the food sits in the drawer floor and in its own rendered fat.

    Manufacturer reference: 4239CY300EUUK

    People replace it because: the non-stick coating has worn or is peeling; it is lost, or was missing from the box; it is cracked, warped or broken.

    Flaking coating is the end of that part's working life. Keep metal utensils and abrasives off it, which the manual requires.

    The 7.6-litre AF300UK and the 9.5-litre AF400UK use different plates with different references.

  • Drawer

    Drawer 1 for the Ninja AF300UK

    The first of the two outer drawers. The manufacturer numbers them rather than naming sides, and they are separate parts with separate references.

    You can fit this yourself: Slides out and back in; no repair involved. Order Drawer 1 by its own reference and check which of the two you need first.

    Manufacturer reference: 4237CY300EUUK

    People replace it because: the non-stick coating has worn or is peeling; it is cracked, warped or broken; it cannot be got clean any more.

    Replace rather than persevere with a drawer that no longer closes squarely or whose coating has begun to flake.

    The model identifier is on the rating label. AF300UK parts do not fit the AF400UK.

  • Drawer

    Drawer 2 for the Ninja AF300UK

    The second of the two outer drawers, sold under its own reference rather than as a pair with the first.

    You can fit this yourself: Order Drawer 2 by its own reference. If you are unsure which drawer you have damaged, the manufacturer's parts store lists both and the numbering matches the manual.

    Manufacturer reference: 4238CY300EUUK

    People replace it because: the non-stick coating has worn or is peeling; it is cracked, warped or broken; it cannot be got clean any more.

    Same as Drawer 1: flaking coating or a drawer that will not seat is a replacement rather than something to work around.

    Check the rating label, and check which drawer you need.

Recall and safety status

Recall status not checked

No verified recall or safety notice is currently recorded in AirfryerHQ for this appliance. That is a statement about this catalogue and not about the product: AirfryerHQ holds a small number of checked alerts and is not a copy of the UK register. Check the authority's own register before concluding that an appliance is unaffected.

The Office for Product Safety and Standards publishes the UK register of product safety alerts, reports and recalls on GOV.UK, and Electrical Safety First operates a recall checker for electrical appliances. Registering an appliance with its manufacturer is what makes a direct notification possible.

AirfryerHQ has no recall data feed and has not checked. That is not a clean bill of health — it is an absence of checking, and it is recorded as one. Check the manufacturer’s own recall page and your national product-safety register.

About this model

A dual-basket machine one size down from the AF400UK, with the same two-independent-drawers architecture and the same Sync and Match functions. It is in the catalogue partly on its own merits and partly because reading two manuals from one manufacturer is what established which of their statements are model positions and which are company positions.
