I try to lube the fan in fall before the heater is used. However, I think the bearings are sealed as it doesn't seem to help. In a few years the fan starts getting moisy.
I suspect the heater makers use cheap fans with sealed bearings so people replace the heaters sooner; the elements and switches far out last them
Anyone found a solution? Learn to enjoy listening to the fan instead of the radio or TV or stereo?
I've tried using fanless heaters such as the hot oil radiator type but sometimes they just don't heat well enough.
TIA
