Re: whirlpool fridge/freezer
The cooling fan motors are usually synchronous motors (no capacitors) and it’s not unknown to get a bearing failure in one especially when it’s been running hot for ages.
Have you had a look at it’s rating?…you can get universal fan motors which will do the job quite happily and probably a whole lot cheaper than the manufacturers gen part.
If you send all the details to spares@ukwhitegoods.co.uk i’m sure something would be sourced for you 😉
