SOURCE: blower motor

Hill, which blower motor? The exhaust inducer or the room air blower? If you are referring to the exhaust blower, check for a restriction in either the fresh air inlet, exhaust pipe or condensate line. If you are referring to the room air blower and you already replaced the motor, it is most likely a relay on the control board. You will need to replace the whole board. More info is always better!

SOURCE: carrier 58mvp furnace ecm motor is making viberating noises

ecms are pretty reliable and electronic failure is much more common than bearing or bushing wearout. i suspect the fins on the blower may be coming loose from their pressed on spline and that will start a vibration or shimmy or you could have thrown a weight that balanced the wheel . best to use to warranty to get a new wheel. good luck

SOURCE: ecm motor on york package unit, motor does not run

If the shaft doesn't freely spin then the bearings have seized and quite likely will not free up. Check to see if there are oil ports on the motor. If there are little plugs on the motor, make sure electric is off and then take out plugs and get a zoom spout type container of oil and put a very little bit of oil in them. Plug the ports back up, move the blade around a little. Re-energize unit and see if it starts.

I have a Bryant hvac system, model 315aav / jav, that started making a loud buzzing noise whenever the fan is running, whether on furnace or a/c. Any ideas as to what the problem might be?


I would say that either you have a loose fan guard ,you have a contactor that is loose and not making good connection, or a motor that is getting bad. Possibly the strap holding the fan motor is loose around the motor and letting it vibrate
I would try to narrow down if it is vibration buzz or a motor or is it coming from the area where all the control parts are

The bearings are bad. You need to replace the motor. Motor cost $75 to $125. Labor is on avg. $150 to $400 with an decent A/C Company . You can try to oil it but its not recommend by Lennox. That furnace at the time they build it was top of the line. Good Luck.

Make sure to check and see if you do not have any bare wires touch ground or if you have any wires pinched causing a short to ground. Safety first so turn of power before checking. Also check to see if any wires on unit are touching one another. Hope this helps you.
