My bedroom furnace squeals upon start up then quiets down. It's the original furnace. Is it very difficult to pull it out and rebuild or replace? Can I still buy a new unit? 1996 U295.
Thanks
Lube the motor shaft bushings .
How do you get to the motor shaft bearings?
Access the furace from the outside. Locate the two ends of the motor shaft.
Use a light viscosity non detergent oil (sewing machine oil is a good choice).
I put a drop at a time on the end of a long screwdriver and "drop it" on the shaft as close to the motor as possible.
Put 4-5 drops on each end of the motor. It will wick in to the bearing/bushing area.
The perfect tool for this task is the Zoom Spout Oiler. Find them at Lowes's, HD, or most hardware stores.
