Question My ac unit is about 8 years old in FLorida. The airhandler seems to be lounder than usual. I suspect a bearing is going bad. Can the motor be repaired or is it more cost effective to replace the blower motor. Could it be a piece of debris in the blower wheel or something other than a bearing. The louder sound is like almost a loud humm. Also I inspected the motor and it has a lot of side to side slop, when I grab the motor stem where it is attached to the blower wheel I can move the rod back and forth between 1/8 to 1/4 inch. I sounds like a bearing to be ?
Answer It does appear to be the motor bearings and a new motor would be the cheapest way out. Take the original motor to get an exact replacement and also get a new capacitor. You can power the motor with the panel removed and turn it off and watch it stop to ensure you have a motor problem. Thanks J
