High Speed Motor Noise on GCH90904CX, GCH950904CX, *MH950704CX, *MH950904CX, GKS90704CX, & GKS90904CX Furnaces
Type: Service Alert
Recall or Alert Date: 11-16-2010
Serial Number: SF-039
Brands Affected: AmanaGoodman
Goodman has received reports of indoor fan motor noise on some GCH90904CXA*, GCH950904CXAA and GCH950904CXAB counter flow model furnaces. In addition, we have received similar reports on up flow models produced with 0911****** and later serial numbers.
Testing has shown that this noise is present in a small number of furnaces when operating on high speed. High speed operation should be used only when it is necessary to provide indoor air for cooling mode based on 400 CFM per ton. If it is necessary to operate the indoor fan motor in high speed and an objectionable noise is evident, the 0131F00022 motor should be replaced with a 10759415K kit. This kit contains a new motor, motor mounting bracket, mounting hardware and capacitor. Kits are available and can be ordered from Goodman Service Parts.Affected Products:
