Engineer has been out - as oven very noisey once the fan starts to spin - he says the oven is arching during heating and the fan is actually scrapping against the inside of the oven as it spins. Product nearly 6 years old was on extended 5 year parts & 1 year labour warranty. Company now wants to charge for having it repaired. Any advice I thought ovens were suppose to heat up without being affected? Urgent help please.
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.
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.
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.

Re: Noisy Oven when heating up & fan spinning
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.

One of the relay boards is a downdraft relay board....I would be
suspecting the main clock assembly as it is the one that shuts down and
controls everything. This might also increase the fan speed randomly, turn it on at random temperatures etc., You have to get a new board. You can find it here http://www.affordableappliance.com
Kitchen aid is made by Whirlpool. There is a very good chance the then thermal fuse on the back of the oven has tripped. Whirlpools are very prone to this fuse tripping after a clean cycle. The noisy fan is just that a noisy fan it will probably need replacing. I have replace a couple of them over the years. When you pull the oven out to replace the thermal fuse replace the fan motor at the same tiome.
If it is a fan assisted oven and it is not getting hot, then the chances are that it is the oven element that is faulty.
This is located at the rear of the oven compartment, behind a removeable cover.
Hope this helps.
You possibly need to fit a new fan motor, as this will certainly cause temp variations, if it is not working properly.
If you remove the inner rear cover of bottom oven, you will see the element and the fan.Try spinning the fan by hand, it should revolve freely, and rotate on its own after spinning it by hand.
If it does not, then it needs replacing.
It is a fairly straight forward job to replace, just bear in mind that the fan is held on by a left handed nut, so to undo it , hold the fan blade, and unscrew the nut clockwise, as though you were tightening it up, and vice versa to tighten it.
You will have to remove the main rear cover of oven to access the the terminals and the fan motor.
next itme you get an authorized co. to come look at it ask them to call the "techline", f&p has an excellent tech resource hotline for us tech ive never called and had them not at least lead me in right direction.
