I am looking for a replacemnet Fan Assembly for a Myson Orion 75Si wall mounted gas boiler GC Appliance No 4149421. The Fan Asembly part number is 309A634.
The boiler is approximately 12 years old.
I am told the part is not available in Dublin and I will not be able to check this until January. Any ideas of where I can get the part in the UK?
I believe the problem is that the bottom bearing on the vertical spindle is worn and sticks. I would swap the top and bottom bearings if I could take the fan apart but cannot remove the lower bushing to detach the fan from the motor.
There is a replacement fan for this model. It is THORN 4430268 FAN ASSY WFFB1202-0081

If you can get the bearings out then the size you want is a
6mm diameter (shaft size) with an outside diameter of 19mm with a depth of 6mm (from memory)
the bearings can be difficult to remove so if you cant get the part you have nothing to loose.
