This can be heard at low speed. two to three bars on the blower speed indicator. It sound like running water. It is not the air conditioner when the compressor in on. I can not listen to the radio all the time..... when it is peace time, radio is turned off. I sounds like the bearing is going. Had it looked at and was told that it is normal. The DC motor is suppose to be quiet? Any ideas?
Thanks for the info. So with the fan running counterclockwise, which direction does that make the air flow below the fan, ie: is it pulling the air up or pushing it down?
