My main cabin AC unit is making a racket when its working. I had a look and noticed that if I hold on to the blower and pull aft slightly that all rattling/noise goes away. I'm thinking the blower motor bearings or something is wearing out, the boat is 3 years old now and this is basically running a lot of the time (been partially living aboard until May this year when I went full time).
I see I can purchase a replacement blower assembly for about 310 dollars. Any one else had this kind of issue?

I see I can purchase a replacement blower assembly for about 310 dollars. Any one else had this kind of issue? If pulling the blower slightly makes the noise go away then it likely is not the motor bearings, but you can check that by grabbing the blower wheel and wiggling it in and out, and up and down looking for excessive play. There will likely be a little bit of end play, (in and out on the shaft) but too much will get noisy. Check the blower wheel an make sure there is no debris of any kind stuck to the wheel. Even a little piece of paper can throw it out of balance. If pulling on the blower housing makes the sound go away it could be that the blower wheel has slipped on the shaft and is making contact with the housing. A motor bearing failing after only 3 years is definitely premature. If it is the motor, and it is not under warranty, you may be able to find a cheaper replacement from aftermarket sources. Look for nameplate information on the motor itself. Information like make, model, voltage, FLA (full load amps) and frame number,(FR), are all useful info. Frame number is important because that tells the supplier a lot of info about body size, shaft size, mounting type etc. |

You might try and squeeze in some lubricant , that helps . Done it several times with the engine room blower and also computer fans . But that has to be repeated now and then as the wear will not go away .
It's worth a try considering 300$ or so .
