Boiler stopped working Glow Worm Micron 60ff?

Had exactly the same problem - a humming noise from the boiler and no heating. Isolated boiler from mains power, removed casing and although fan motor would turn, was a little stiff. A liberal squirt of WD40 at both ends of the motor and tried boiler again. Fan worked fine and heating was restored. No need to remove the fan or any components.
