There is a problem with the fan situated at the top of my Optia FF50 boiler. When the boiler is first switched on the fan comes on and it makes a horrible squeaky noise whilst running. The boiler fires up for a few seconds and then the fan cuts out and as a result the boiler goes off. The fan motor is hot so I am sure that it is a problem with the fan motor. However it is in a sealed unit that I cannot get into.
Does anyone know anything about these and whether it can be repaired at a low cost? Any advice would be much appreciated.

Any idea how much a new fan is likely to cost?

yes it can be repaired but not by you.
you'll need a corgi engineer to fit a new fan as its part of the flue.
