If the oven fan stops, or starts squealing, it can be changed with a fairly standard oven fan, but you will need access to the back of the cooker and inside the oven.
Warning. Do not attempt if you are not competent with electrical wiring. Cookers usually have a 30 Amp fuse and any mistakes could be lethal.
