Question : Carrier HVAC Condenser Fan Motor is very loud.?
When comparing units with my neighbors ours is VERY loud when running. It sounds like the outside fan on the unit is going bad. If this stops running, what happens to the unit? Will it just not turn on anymore? It’s a Carrier model #: 48gs-024060301. Is it difficult to replace the fan motor?
Thank you Sandshar! I was concerned that since the unit has gas going to it I’d have to shut that off to change the fan motor outside. Really, it looks as simple as taking off the side cover and the fan guard, then just routing the wires and loosening a few nuts to replace the motor. Yes, I read the capacitor needs to be replaced too. It appears that the motor costs around $ 200 and the capacitor would be about $ 20. I’d have to pay for about an hour labor too if I did not do this myself. My neighbors unit (same kind) is so quiet you can’t even hear it turn on and ours is so loud that you can hear it one house away. This just started all of a sudden in the last 3 weeks since it was last serviced.

If the condenser fan motor stops running, the unit will shut off on its high pressure control, if it has one. If the control is manual reset, the unit will stay off until the control is manually reset. If it doesn’t have one or if the control is of the automatic reset variety, the compressor will eventually overheat and shut down on its internal overload protection, in which case it will eventually reset itself and do the same thing over and over until the compressor burns up. No, it is not that difficult to replace the condenser fan motor and run capacitor.

Additional details response:

You’re welcome. It’s really not that difficult if you have a little common sense, a few tools and you pay attention to how everything is taken apart and how the wires are connected. Just be sure to turn off the power! Also, the fan blade might give you a little problem getting it off the shaft. If the shaft sticks through the blade hub, you’ll need to use some sandcloth on it and spray some lubricant (WD-40) to help get the blade off. Be careful not to bend any of the blades.
