So my refrigerator evaporator fan has become too weak to turn.  Well,
it turns, but very slowly maybe 1 RPM when the normal speed is 3000 or
so. I have a new one on the way but, before my food spoils, is there
any way to perhaps resurrect this existing fan, just to keep it going
for 2-3 days until the new one arrives?  I wiggled it once or twice
which initiated full speed, but it didn't last.  I also tried lightly
oiling it but no difference.  Thanks in advance.

 
You did not say if it turns smoothly when you move it with your finger.
 
(I do not know what is a weak fan, though)

Sorry, yes it does turn easily with finger.

Check for winding continuity. If open cct, you'll need to replace a
thermal fuse located near the end of the winding, under unsulation.
