Noisy Oven when heating up & fan spinning

I have a b600 oven and we've replaced the element but it's still not working can you help [email protected]

I had a problem with a noisy fan on a Baumatic B600 oven. It was driving me mad! Very rattly and would change with temperature. I tried oiling the bearings...no good. I thought the fan was out of balance...wasn't. Was on the point of ordering a new motor/fan assembly, when I noticed that the noise would sometimes start even before the motor even got up to speed. Solution: It's a design fault IMO. The back panel is made out of steel and is fractions of an inch from the fan motor, which is an induction type. The magnetic field from the motor makes the back panel behave as a loudspeaker. To test the theory, I held a screwdriver up to the motor and it grabbed it magnetically and vibrated at 50Hz. The solution was to remove the fan cover circular part of the back panel. Just file between the outer holes, or use a jugsaw and it'll be done in a minute. Result? Absolute silence!! You can't even tell the oven is on! And to think...I've been living with this for over a year, having to turn the kitchen radio up to hear it above the din! Baumatic...your design engineers need a bit more training in basic Electricity/Magnetism.

Neth, Im not familiar with this oven but I thing someone is handing you a line. I've been doing this for 30 years now and never saw a oven cavity arch when heating. The fact is that there is something wrong with the fan motor or fan blades itself. Call this cat back and have them honor your warranty...Catriver..post back.
