    York Blower Whine and Rumble

    I have a recently installed York TM9X100C20MP11. It replaced a 20 yr old Carrier system.

    When starting up I hear a low whine (like a turbine) until its get up to speed. The installer told me its normal for units with an ECM motor to whine.
    When stopping the whine returns but for a longer time and is louder.
    Towards the end (last few seconds) I hear a rumbling sound.

    Are these sounds normal?

    Thanks for your response.

    How many times must one fix something before it is fixed?

    I hear the wine and thump on many ecm motors but not with the fixed speed ecm motor I believe is in that unit.

    We have had customers mention the thump and wine but not on your furnace. I think you are hearing what is called the draft inducer motor which runs before anything else does.

    If it was the inducer, I wouldn't think he would hear it for a longer time when the heat shuts off.

    Blower motor failure is near. Bearings are failing. IMO. York can be very expensive.

    System won't let send video. Audio wasn't wasn't best as low frequency rumble was barely picked up the camera.

    Thanks everyone for your comments. I'll contact my installer after the holidays.
