Convection oven no longer works

Most wall ovens have a cooling fan that comes on when the oven has been on for some time. It is separate from the convection operation. It should shut off after the oven has been off for a time.

f the oven doesn't heat and the on-off light works, test the appliance controls, motor,
and heating element .

It is most likeky that the fan bearing is worn and thus causing the rattling sound. You will probably need to replace the fan. Check first that there is no obstacle in the way of the fan rotating.

Replacement of the fan will require the back of the oven to be removed giving access to the fan unit, which will need to have the wires disconnected and the fan assembly unbolted. Fitting is the reverse.

Always remember to switch off the power before working on electrical equipment.

You don't tell the age of the oven... but the convection fan motor bearing is stressed by the heat of the oven.... and over time can cause all sorts of noises.

You may want to place a small amount of WD-40 on the convection fan motor bearing... just to confirm it as the problem/

Best to replace the motor if it is the problem..

ensure that your convection fan is turning
a hum on this model usualy means that the convection motor can seize up a bit
sometimes all you need to do is redjust the fan blade

If your fan is blowing cold air, it's the air inside the oven that circulates. It has nothing to do with the fan. Convection circulates the existing air in the oven. Sounds like you might deselect the convection setting if this continues to happen. We have parts, so please let us know if we can help any further. :>)

Your temperature sensor is failing. Replace the temp sensor.

The convection fan is wired through the door switch make sure your door switch is o.k. before replacing the board or the fan. Please have a local service tech check unit if you have to get into any electical checks. good luck

is the control electronic wih a dial or the whole manual if you can answer me with the model number i can look it up there will be a serial plate some where on the front of the oven most of the time you open the bottom drawer mod#is a bunch of numbers like 106.48062890 should be able to help more after that

Check for a bad fan motor or a jammed blade.
