SOURCE: zanuisi top oven making noise

Yes , there is a cooling fan located at the top of the oven
It could be the fan blades catching, or a noisy fan bearing.
You would have to access it by removing the top oven cover to check., and yes it could be as a result of having it cleaned.
Plz rate my solution.
Thanks.

SOURCE: noise from fan when electric oven is first turned on

The fans are not normally repairable, but there is no problem obtaining replacements.
On a double oven, there are usually 2 fans fitted.
There is an external cooling fan usually fitted on the top of the oven, you would have to remove the top cover of oven to access it, and possibly the rear panel as well.
Then there is the fan fitted in the main oven compartment.
If you open the oven door as it is working, you should be able to determine if it is the fan oven or the external cooling fan that is the cause of the problem.
If you determine it is the fan in the oven that is noisy, then to undo the fan blade assy, you have unscrew the nut clockwise to remove it. as opposed to the normal way of undoing a nut.
Please rate my fixya solution.

If it is a fan assisted oven, then you are likely to have 2 fans, an external cooling fan, and a fan inside the oven for ciculating the hot air.
So to answer your query, yes it is a noisy fan you are going to have to establish which fan.
It could be a worn bearing, or the fan blade has come loose.
If it is a worn bearing, thge only cure is a new fan.
Hope this helps with your problem.

Testimonial: "Thank you for that. It's noisy even when the fan inside the oven isn't running (ie, just on convection) so guess that means it's the external fan?"

SOURCE: RATIONAL COMBI OVEN ELEMENT GLOWING RED -IS THIS NORMAL?

your oven is electric yeah? the hot air element shouldnt be glowing like that, it glows with the door open? the oven has a over temp stat so if the oven got too hot then it would trip out, if it does then the solid state relays will have to be changed, but if it carries on as normal then shouldnt worry
