Question about Heating & Cooling
This is almost certainly a dry bearing on the fan motor. If there is little or no oil on there, a little rust may form and the next time this is powered up, the rust comes off - but is polished onto the bearing - creating the squeek.
Buy a can of maintenance oil in a pressurised can, and squirt some on the bearings at each end of the motor. It doesn't matter if it drips or runs down anything. If there are 2 separate motors - you need to oil 4 places.
If the unit is very old, it may use a motor with brushes. I'll give more details if the oil doesn't work.
Thanks for using Fixya - and if this works, please rate as such.
