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.

Sorry, yes it does turn easily with finger.
I have trouble understanding what is a weak fan. I have seen fan fails for two reasons: either they don't turn easily: possibly lack of oil, maybe a combination of oil/grease and dust/hairs making the axis stuck. The other reason, on big fans, is that the condenser fails. Wire breakage seems rare.
If a small fan doesn't have strength to turn, it turns easily, and there is no capacitor, I don't know what it is. On DC type of fans, with a permanent magnet, that magnet may have lost the force.
