The first tells you about the convection fan, the second about the cooling fan. An oven whose cooling fan has stopped will cook normally for months and then take its control board with it, which is why it is worth checking even when nothing seems wrong. ### Two fans, two jobs The convection fan sits behind the back wall of the cavity with its own element around it, and it is a cooking component — it makes the oven even and faster. The cooling fan sits outside the cavity and moves air through the housing to keep the electronics and the surrounding cabinetry within their limits. They are different parts, they fail separately, and only one of them changes how your food comes out. ### The one that matters and nobody notices A cooling fan that has stopped produces no symptom at all until something expensive fails. The oven cooks normally; the console behind it gets hotter than it was designed to, month after month, and one day the control board is dead. It is the reason we listen for it on every oven visit even when the complaint is something else entirely. The convection fan motor Bearings, or the motor itself. Usually announces itself as noise long before it stops, which is a warning worth acting on. The convection element behind the fan The fan turns and the air it moves is not hot. Results go slow and pale rather than uneven, which is a different complaint from a stopped fan. The cooling fan Protects the electronics and the cabinetry around a built-in oven. It running constantly is normal; it never running is not, and it is the quiet cause of dead control boards. Something fouling the fan A rack out of position, or foil that has found its way behind the back panel. Free to fix and worth a look before anything is ordered. The control that switches the fan Least likely, and last. A fan that is silent on every mode with a healthy motor points here. Listen on convection At the door, with the oven up to temperature. A convection fan is audible. Listen after switching off The cooling fan should keep running for several minutes. Silence immediately is worth reporting. Compare bake with convection Even on bake and uneven on convection points squarely at the fan or its element. Look for anything touching it Cold oven, back panel visible. A rack or a piece of foil against the fan is not rare. Two fans, and only one of them cooks What it usually means Convection results gone uneven or slow A silent oven that used to hum A fan that runs on long after cooking, or not at all The fastest diagnosis is what you can see Run the oven on convection and listen at the door, then switch it off and listen again five minutes later.

No, that is the cooling fan doing exactly its job. A built-in oven has to get heat out of the housing after the cycle ends, and it can run for a good while. What would be a problem is the opposite: no fan at all after a long bake. ### My convection results have gone uneven. Fan or element, and they are told apart by how the food is wrong. A stopped fan gives you an oven that behaves like a conventional one — hotter at the top, uneven front to back. An element that has failed behind the fan gives you even but slow and pale. ### It has started to whine. Worth acting on rather than waiting. A fan bearing announces itself for weeks or months before it seizes, and a fan replaced on a noise is a much smaller job than one replaced after it has taken the element or the board with it. --- **[Read full article: Oven fan not working](https://bertazzonimiami.support/symptoms/oven-fan-not-working/)**
