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.

actually it takes less time to heat up and cook with the fan running
That is why it is called a fan forced oven as the fan forces the hot air all around the oven , heating it quicker and giving a better cooking result by moving hot air all around what is being cooked
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
The Fan has ,in most cases, two functions - to maintain the oven temp and to clear any condensate or smoke coming from items being cooked. If your oven is over heating it could be the thermostat sensor faulty and giving a faulty reading to the fan. If you set you oven at 350F then sensors control the heat by kicking the heating elements off and in some models and makes the fan aids cool down. Make sure it is at a temperature that would trigger the fan to cool it down. It mostly relies on the regulation of the heating elements to control the temp. Only if it were to get hotter than the elements kicking off can control should the fan kick on. Not being at the site and actually seeing the stove it is hard to determine but if the fan is working every where else it should work when the oven is heating. Again check and see if there is a seperate sensor that monitors the temp of the over and triggers the fan. Not much help but that's where I would look first. Hope this was of some help.

F2 during the cleaning cycle will occur when the oven control senses an oventemperature above 915F-930F
If actual over temperature condition occurred: Look for welded relay contacts. If this happens, replace oven control (also called clock or ERC).
If no over temperature condition occurred: Look for a high resistance connection or any other cause of high resistance in the oven temperature sensor circuit. Check sensor, sensor harness and sensor harness connection at sensor and oven control. Replace sensor if found defective. Check door lock switches.
Remember: Oven control (ERC) measures resistance of sensor circuit , not actual oven temperature.
**((The fans will continue to run if the control has been damaged, due to the high heat))
