I have a small heater fan marked Krups type 984. The fan motor and the
whole unit appear very clean and nothing seems burned or damaged. The
problem is the fan doesn't spin with power applied (it tries to spin,
turning very, very slowly). I can turn the fan by hand and it feels a
little stiff.

It seems maybe the motor just needs lubrication but I don't know how
to do it properly. Do I need to remove the fan blade to get at the
motor? How? Do I need to clean the motor bearings before adding new
oil?

Assuming it's the typical shaded pole motor,

It's best to remove the fan blades and disassemble the motor to remve
the shaft from the bushings.

Then. clean out the gummed up bushings and the shaft, put a couple
drops of electric motor oil on the shaft and bushings, reassemble
in reverse order.
