Just over a year ago I replaced the fan motor on our Bosch oven which was only about 5 years old. Now the new fan has become very noisy and it appears that the bearing has worn out.
This is not impressive. Have I overlooked anything - should the new motor have been lubricated for instance?
I took my motor to bits and greased the worn bearings (bushes) with high temp copper grease (as used on car brakes). It is as silent as the night.
The motor is 15 years old!
