Question About Lennox International Inc. Furnace G21Q
Lennox G21Q furnace...

The blower is now making a loud high-pitched whining noise. Can anyone suggest anything, please? There's a little plastic yellow plug on the top side of the motor. Does that take oil/lubricant? Maybe it needs to be lubricated, even though the manual says it's pre-lubricated and shouldn't need more. Furnace is about 15 years old.
