Electrolux’s Air Fry mode, built on the Advanced Convection system in its current wall ovens, works by circulating hot air aggressively around food rather than simply surrounding it with still heat, which is what lets it approximate the crisp texture of a countertop air fryer at a much larger scale. Because that entire approach depends on strong, evenly distributed airflow, any disruption to the convection fan or its motor shows up directly as uneven cooking — one side or section browning noticeably faster than the rest.
Some Unevenness Is Normal
Even a fully functioning Air Fry mode will not produce perfectly identical results across every square inch of a tray, particularly with food that is crowded too close together or stacked in a way that blocks airflow to parts of the tray. Leaving adequate space between pieces and using a tray sized appropriately for the oven cavity, rather than a smaller pan pushed to one side, resolves a fair amount of what looks like an oven problem but is really a loading issue.
When the Pattern Points to the Fan
A strong, consistent pattern — the same side or corner underperforming every single time regardless of how food is arranged on the tray — is a different story, and it typically points at the convection fan itself running unevenly, losing speed, or a fan motor that is beginning to fail. A fan that sounds different than it used to, louder, quieter, or with a new rattling or grinding note, supports that diagnosis further.
Checking Oven Temperature Accuracy
Before assuming the fan is the cause, it is worth confirming the oven is actually reaching and holding the set temperature accurately in the first place, using an independent oven thermometer rather than trusting the display alone, since a temperature that runs consistently low can produce results that look like uneven cooking but are really just underdone food across the board.
Tray and Rack Position Also Change Results
Air Fry mode tends to perform best on the rack position and tray type recommended in the oven’s own manual, and substituting a heavier, darker pan than intended, or placing the tray on a rack position designed for conventional baking, can produce results that look like a malfunction but are really a setup mismatch. It is worth confirming you are using the manufacturer’s recommended tray and position before concluding the oven itself has a problem.
What to Do in the Meantime
Rotating the tray partway through cooking is a reasonable workaround while you wait for a repair, but it should be treated as exactly that — a temporary workaround, not a permanent fix for what is very likely a convection fan problem underneath.
Preheating Fully Before Loading Food
Air Fry results also suffer when food is added before the oven has finished reaching its target temperature, since the initial, slower ramp-up period can leave one side of the tray exposed to lower heat for longer than the rest. Waiting for the oven to confirm it has fully preheated, rather than loading food as soon as the door is opened, is a simple habit that improves consistency regardless of whether a fan problem is also present.
