Why is my central air conditioner making a whining sound?


Answer by  Sandrion (203)

It could be because some of the internal motor parts are wearing out or it could just need to be oiled and lubricated to ensure that it is not being worn out prematurely.

The root of the problem could be the condenser fan motor or the compressor. This is a problem that you need to call a professional to investigate immediately. An ounce of prevention is worth a pound of cure. Replacing a bad compressor will run more than a thousand dollars so you will want to get this looked at.

Could be some thing like a leaf or dust getting in it,Also check if it's freezing up or dust is bilt up on the radiator's Making the electric motor work hard and make a whining sound.Another possible reason is if let it set over winter it could have rusted motor bearing's,last thing to check would be a internal transformer.

Trust me, if it is making that whining sound, then there is a big defect in the system. There may be something stuck in the fan. Perhaps something sharp may be stuck.

If your air conditioner make a whining sound then check the belts. Probably these are loose. If the compressor runs for a long time it can make sound.

If you hear whining sound from your central air conditioner, it conveys warning signals along to your central air conditioner. this means central air conditioning system is heading for a breakdown.

Basically, there must be some kind of defect in the fan and that is why it is making this kind of noise. Also there must be an item dropped in the air conditioner.

My air conditioner wishes it was as cool a cat as I am. But since it does all the work and I just sit and enjoy, it's singing the blues and whining.
