Verify the temperature of the oven by using an
oven thermometer and make sure that it is even
with the thermostat setting.
If the oven is baking too much on the sides, it is
possible that the fan is not cycling properly.
Verify if the motor turns 2.5 minutes in a
direction, stops 30 seconds and starts for 2.5
minutes in the opposite direction.
