Chefman 4-Quart Compact Air Fryer: problems, parts and running costs

Checked: 2026-10-05

Summary

The Chefman 4-Quart Compact, model RJ38-4T-BLACK, is a 1500 W single-basket fryer, and its wattage and 4 qt capacity explain nearly every complaint owners and testers report: fries and wings take longer than the package instructions allow, and meals for more than two people have to be cooked in batches. No replacement parts are published for this model, so a cracked basket or a dead control board is a warranty claim or a disposal, not a repair. It is a good buy at $60 or below, where you are paying for the small footprint, the dishwasher-safe basket and the 450 °F Hi-Fry finishing step; it is a poor buy anywhere near the $99.99 Chefman list, where better-tested 1600 W fryers of the same size sit.

Common problems and fixes

Fries and wings take longer than the package says — the one independent test of this 4-quart family found fries needed extra time on top of the package instructions, and put the cause at 1500 W against the 1550 W and 1600 W fryers in the same size class. There is no fix; run the fry a few minutes longer than the label says, or preheat longer before adding food. Not a defect and not a warranty issue. [1]
Small basket means cooking in stages — the 4 qt basket is rated by the independent outlet for one to two people, and Chefman’s 1.5 lb fry load is a basket-volume claim rather than a tested result. Cook in batches and expect the total time to eat into the savings of a single large batch. Sizing, not a fault. [1][2]
A seller can ship you the windowed version — Chefman sells the non-window RJ38-4T-BLACK and the windowed RJ38-4TW-BLACK as two separate products at the same list price, and third-party pages routinely attach the windowed unit’s photos and feature bullets to the non-window listing. The basket window and the interior light belong to the windowed version only. Check the product graphic before ordering. [3][4]
The four presets do not match the descriptions — the control panel photographed for this exact model reads FISH, FRIES, CHICKEN and MEAT, while published descriptions of the same machine list Air Fry, Bake, Roast and Reheat, or Air Fry, Bake, Cook and Dehydrate. Trust the lettering on the panel and ignore the function names in a listing. Not a warranty issue. [1][2]
Build reads as thinner than the alternatives — the same hands-on test described the construction as feeling less durable than the fryers it compared against, and nothing in the sources suggests a repair route for a cracked basket coating or a bent drawer. Ordinary wear is outside the 1-year warranty. [1]
A unit that keeps running after the timer ends — Chefman-level owner reports describe a fryer that stopped cooking once the timer expired and had to be switched off by hand. On this model that falls inside the 1-year Chefman assurance, and the unit also shuts itself off when the drawer is pulled out, so pull the basket rather than relying on the timer. [2][5]
A control board that burns out — one brand-level report describes a Chefman fryer that stopped working with a burnt control board after eight months, with support declining help after the owner opened the top compartment. Eight months is past this model’s 1-year term, and no boards are sold separately. Not covered. [5]
Temperature below the setpoint — one brand-level report says a Chefman fryer reached only about 300 °F at its highest setting. No fix is documented; check the result with an oven thermometer if setpoint accuracy matters to you. Not a warranty issue unless the reading is bad from the first cook, which the 1-year term covers. [5]

Parts and consumables

No replaceable parts or consumables reported.

Chefman’s document library indexes user guides for the range, but no replacement-parts catalogue was found for the RJ38-4T basket, removable crisper rack, control board or heating element, and whether Chefman sells any of them separately is unknown. The basket and its crisper rack are nonstick and top-rack dishwasher safe, which is how the two most damage-prone pieces are meant to be maintained. No filters, pods or proprietary consumables are documented for this model. [4][5]

Yearly running cost

Not enough data.

No source gives a measured power draw or an annual electricity figure for this 1500 W appliance, and there are no filters, pods or subscriptions to pay for. The recurring spend owners describe is ordinary food cost: cooking oil or spray, and liners if you use them. No price for any of that was read. [5]

When it is a good buy

US store prices observed in October 2026: $59.99 at Best Buy for the RJ38-4T-BLACK, sold and shipped by Chefman Direct; $42.75 for the non-window 4 QT Compact at the Air Fryer Sale specialist store, against $44.25 for the windowed one; $57.99 on Walmart and $85.77 on eBay as tracked by the Youbil price aggregator; and a $99.99 Chefman direct list price shown for both 4-quart variants on the Chefman collection page. Sam’s Club showed a members-only price that was not displayed, and Target showed the 4-quart out of stock. [1][2][4][6][7]

Under $50, low risk: you pay for the format and accept the slower cooking and modest build.
$57.99 to $59.99, where mass retail sits, still reasonable; the tested evidence supports the machine’s function but not its build longevity.
Above roughly $80 the case thins, and above $100 nothing in the evidence supports the figure.
Treat any Chefman-branded storefront mirror as unreliable: three of them showed the same 4-quart at $79.99, $99.99 and a $28.00 sale price.

Named alternatives:

Instant Pot Vortex Plus 4-quart, 1600 W — the fastest unit in every test the independent outlet ran; the better choice when cooking speed matters more than footprint.
Ninja AF101, 1550 W — same size class, higher wattage than this Chefman; the better choice if you want more margin on cook times.
Dash Tasti-Crisp 2.6 qt — took the outlet’s one-person slot; the better choice if you cook for a single person and do not need a large basket.
