Lamona LAM3400 Oven fan made lots of noise and then stopped working

I will try and help with this problem...

Hi sorry for the late response. I was away yesterday. The noise might be either coming from the fan or the bearing on the motor has collapsed. 

I have put a link to a video to help you replace the motor. The fan motor for your Lamona LAM3400 Oven can bee found below.
