Loud heater fan
#1

I have a York gas hot air furnace. When the fan first starts it is very loud, it quiets down when it reaches full speed. The motor is sealed and cant be oiled. What can I do to make it quiet?

If you are sure
the noise is from the motor and the motor is sealed---motor will have to be replaced.If you or a friend deal with Graingers--remove motor and take it to them---probably cheaper then a OEM motor--doesn't hurt to call around--a sleeve bearing motor will cost less---but make sure you oil it once a year.PDF
