Why does my oven's fan keep running after I switch it off?

Not necessarily. Some ovens have a cooling fan for electronic controls that can run while baking and continue after the oven is switched off. GE describes that behavior as normal for the models covered by its guidance, but that does not tell us whether your particular oven should behave the same way. [S1]

Check the manual for your exact model. Look for its description of the cooling fan and what it says about operation after cooking. Don’t assume that every fan sound or run time is normal just because another oven behaves that way.

Use the manual’s wording rather than guessing from the sound alone. If it describes a cooling fan for the controls that may continue after cooking, compare your observation with that section. If the manual does not clearly address what you are hearing, avoid applying instructions from a different oven; the supplied guidance does not establish how to identify fan types across models.

Record what you can observe: when cooking ended, when you switched the oven off, whether the fan was already running, and whether it later stopped. Don’t invent a time limit if the manual does not give one.

Check whether the manual describes what to expect for your model. GE advises checking the model’s manual and contacting the manufacturer or service if the observed behavior does not match its instructions. [S1] The supplied guidance does not establish a universal number of minutes that is normal or abnormal, so a duration by itself is not enough to diagnose a fault.

Note any other problem you observe, such as a display message or a change in how the oven operates. Treat those as observations to report, not proof of a particular cause. If the manual does not settle the question, share your notes with the manufacturer or a qualified service professional.

You can copy this and fill in what you know:

Oven brand/model: [brand and model] Manual section checked: [section title or page, if available] Cooking ended at: [time] Oven switched off at: [time] Fan first noticed: [during cooking / after switching off / not sure] Fan stopped at: [time / still running when checked at ___ / not sure] Other observations: [display message, change in operation, or “none noticed”] What the manual says: [brief summary]

Ask: “Does my model’s manual describe this post-cooking fan behavior, and what should I do if my observation differs?” Providing the model information and your observations can help keep the question focused.

Use the manual for your exact model as your reference. Continued fan operation after switch-off can be normal on some models, but the supplied guidance confirms that only for the models it covers. [S1] If your observation conflicts with your manual, or comes with another problem, contact the manufacturer or service and share what you recorded. There is no universal run time or diagnosis established by the supplied guidance.
