MA-RSD making loud hum/buzz noise

[Oceanairre]

My small (1100 sqft) condo has an EWC MA-RSD installed which makes a constant loud hum/buzzing noise. Is there an adjustment that can be made? Is this indicative of a forthcoming failure? Thanks in advance!

Your motor is failing you will need to replace it. The part number you need is a MA-RSD.

Here is where you can order that part from.

Steve, will replacing just the MS-RSD solve the problem? Is the “motor” that you are referring to the blower motor?

Yes if the MA-RSD is humming then that's where the problem is. All you need to do is replace the motor (MA-RSD).
