Little Giant Fan Noise

Oiling a fan motor is not difficult as long as the fan is out of the incubator. Oiling them properly generally means dis-assembling the motor. HOWEVER, you can try to oil them (as best you can) . There is normally not much clearance between the motor portion & the bearings & oiling the upper bearing is almost impossible because oil does not run up-hill. I would try to oil the lower bearing without removing the fan from the incubator. I'm assuming that the fan is mounted in the lid, so removing the lid & tilting the lid to one side, I'd try to put a drop of oil on the motor shaft so it runs down into the bearing. I'd only use ONE drop (excess oil can get spread all over the inside of the incubator by the spinning motor, you really don't want that).. While you can use any type of oil, I've found that 3 in 1 Oil works best. It comes in small cans with a pointed tip that makes it easier to get into tight places. In fact if you have a syringe with a small needle, that would be even better. 3in1 Oil is a very light weight oil & tends to get into tight clearance areas better than thicker oils.
