circulating fan on hot air system.
The circulating fan or pump I described as running too much sounds like an ufo landing. it runs independent of the furnace and is not blowing hot air out????? Does anyone know what this gismo does?

Assuming it’s the fan, has anyone lubricated the bearings lately? My furnace has grease cups that have to be re-filled every couple of years, as well as oil holes for lubricating the motor. I know I wrote previously that my fan only blows when the heat is on, but my experience with hot air furnaces is limited to a sample of one; yours might well be different.
I don’t know that furnaces have any pumps [but read what I said about the very limited sample size in my experience].
