The fan noise has two reasons: one is that ice forms around them causing strain on the disk brush in the middle, which wares down the brush causing the fan to go out of balance, this causing the loud whinning and sometimes high pitched squilling. This happens when the unit is six months to a year old. The first thing that is suggested by the manufacturer is to let the unit be unplugged for twenty-four hours, allowing the ice to melt from around the fans. It has been my experience that this is only a short term fix. You can repeat this every other month until the revolutions per minute of the fans is so reduced that they no longer supply enough air ciculation to cool the refrigerator or the freezer. The solution to this problem is to replace these fans about once a year. Unless the noise does not bother you.

Air conditioner fan is making a loud noise


1. Could be a caught foreign object between A/C (air conditioning) fan and cooling radiator, producing this loud noise.
2. Could be a damaged fan blade, mowing the cooling radiator.
3. Could be a loud noise comming from the fan's electrical motor.
4. Could be a broken off fin (small wing) of the cooling radiator, striking the A/C fan, producing this loud noise.

Cooling fan


Yes. It can be replaced. Try to check which fan is making that sound. Do you have a laptop or a PC? On a PC, there are 3 standard fans inside it. one for the CPU, one for the power supply and one for the computer casing fan as well. It depends on which of those fans it's coming from. On a laptop, some laptops' fans actually makes a loud noise which is common but there is a way that it could be lessened but it might slow down your pc and it might overheat it as well. The loud noise on the fans of a laptop actually indicates that it's trying to cool down the system. If it doesn't stop the loud noise, it could indicate a problem switching the fans back to normal and would just continue to spin fast. Try to contact your PC tech for further diagnostics on the laptops fan to indicate if the problem is with the fan or the mainboard as well.
