- Check if the fan blade is not broken or unbalance fan blade.
- Check if bolts are tight enough.
- Check if the fan motor rubber grommet is complete and balance.
- Check also compressor rubber grommet is complete.
- Re tight all screws and bolts on the condenser unit.
- Check the condenser installation if balance.

My son has a noisy condenser fan on the carrier condensing unit, model is a BRC060360 and Im puzzled on this unit seer rating, any ideas? Also looking for a budget condenser fan for it?

Condenser fans are usually not very expensive, so I suggest you go to a carrier dealer and buy one as a spare part. Have you check that the fan is clean and none of the blades are damaged.

On a cpkj 48-1B Goodman heat pump I am having condenser fan issues. runs full spedd for a while then cuts down to barely running, Even after changing the motor and capacitor.

Does the condenser utilise head pressure control to maintain head pressure? if so is the unit fully charged...r22. r410 Freon.If the unit is an older model. the fan motor only runs at 850 r.p.m design flaw. The newer units now run the fan at 1075. R.p.m. I have installed many Goodman split systems and was having problems similar to yours. Hope this. Helps you

Condenser fan motor

It would be easier to get the data from the condenser fan motor than attempt to match AC unit model numbers. If unreadable then remove the fan motor and take to someone to match with the one you have. That is what I do, Thanks Sea Breeze
Make sure you mark your wiring before removal.

Condenser fan replaced one year ago, fan not turning but can hear motor

the answer to your problem is most likely the motor start capacitor. A AC motor can run in both directions. The start capacitor is used to cause the current to lag behined the voltage which determines the direction the motor will turn. Its posible the start and run capacitors are in one can. so changing one will change the other. However look for a wiring diagram. Do not asume that both capacitors are wired in properly. They may be fighting one another causeing premature failure.

Whynter Portable Air Conditioner Model: ARC-14S. Problem: It sounded as if something fell inside the unit while it was operating (cooling) then it started to vibrate horribly. The vibration is only...

Hi,Whynter Portable Air Conditioner has many moving parts, and they all make noise and cause vibrations. Some of these parts are more likely to causing shaking and loud noises, and sometimes this signals a larger problem, something to watch and scrutinize. If serious enough, it calls for a repair.

Loose Parts

Loose parts cause the majority of shaking and vibration noises in your air conditioner. A few of the most common loose parts include the air compressor, the piston rods and even the fan or blower unit itself. These noises are clunking, clanking sounds that occur along with a vibrating action. The only method of repair is a complete compressor replacement, which is a repair only a certified air conditioner technician is qualified to make. The compressor is a fully sealed component, so individual parts in the compressor cannot be repaired.

Fan Blades

Fan blades cause noise, shaking and vibrations even when properly secured. If fan blades contact the exterior structure of the air conditioner due to a bent fan blade or broken and misaligned grate, a constant, repetitive noise and vibration results, which sounds like a ticking or banging from the interior of the air conditioner. Vibration in this case is limited but still present.

Mounting Brackets

When an air conditioner shakes, there is a problem with the mounting brackets. These brackets hold the air conditioner compressor steady as it operates. Normal vibrations and shaking would otherwise occur without these brackets. A loose mounting bracket causes the air conditioner to rock back and forth and creates a clanking sound. As the compressor starts up, this rocking and clanking sound begins, resulting in a very loud and fast vibration and noise. It also occurs when the unit shuts down.

Other Sounds and Vibrations

Sometimes air conditioners squeal, hiss, hum or screech. Each noise is often accompanied by a vibration. Humming sounds along with a vibration may indicate a bad capacitor, the electrical part responsible for starting the machine. Hissing sounds tend to indicate a pressure problem while screeching and squealing sounds are fairly common in window air conditioners and in central air conditioners. This sound is also a result of the compressor motor. It usually starts when the unit turns on and continues through its normal operating cycle. Vibrations always occur in the air conditioner due to moving parts and the compressor motor's operation.

Hope it helped..

We require condenser fan motors for Interclisa Carrier package (rooftop) air conditioner model AAD 250 (1980's model) model. Air conditioner - supply voltage 380 Volts 50 Hz AC. Condenser fan motor voltage...

Hi, this is an odd voltage 380 volts. Is it a 3 phase unit? To get a 220 volt 50hz condenser fan motor, you will have to go through a refrigeration/air conditioning parts house and order this. 60hz you would have no problem finding one in stock. Carrier is a good unit, and have been around for many years. You shouldn't have any problems locating one.
PS You will need to go through a wholesale parts house.

Is the condenser fan (outside) turning? You mention that it's hot but don't say if it's turning or not.

These fan motors normally run pretty hot, but not so much that they shut down due to internal thermal overload protectors.

Both the compressor and the fan have termperature overload protectors to keep them from burning out the motor in the event of an overheated condition. The condenser fan must be running or high freon pressure will put an excessive load on the compressor and it will 'kick out' the high-temp overload protector.

Turn off the unit by pulling the outside disconnect (in a small box near the outside compressor unit) or flip the AC breakers in the breaker box. Wait about 30 minutes for the unit to cool off and turn it back on. If the compressor and fan both run for awhile then kick back off, or the fan motor seems to be working under excessive strain, you've probably got a bad motor start condenser (inside the unit) that little round can that is connected through the fan motor wiring. If it's swollen or leaking, it's almost surely defective and even if it's not, excessive load on the motor is a classic sign of a bad start condenser.

You can usually find these at electrical supply stores, well-stocked hardware stores, or most certainly at an HVAC parts house. Be sure to replace the old one with one of the EXACT same value (in voltage and Microfarads (mF) capacity. The shape may be a little different, but as long as the electrical characteristics are the same and is rated at the same or higher voltage than the original, it will work.

Connect the new condenser, mount it to the frame, and restart the unit. This should take care of the problem.

Hope this helps.

Blower motor vibration in a/c unit

You already checked to see if the blower wheel is out of balance by noticing that the a/c unit vibrates. There is nothing else that can vibrate that badly.

Go buy a new blower wheel.
