When it is lcooling it has now begun tomake loud vibrations.

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..

Bad compressor, if the compressor is going bad or the bolts that hold the compressor in place are loose. Check to make sure the bolts are tight. If not check the compressor with your hand and see how much it vibrates.

fan loose or bearings going

If it is a frost free check the fan inside. The fans can have bearing failure after a few years thus causing the vibration. Also the compressor underneath is mounted on rubber vibration dampers and if one of these rubber mounts fail then the compressor will start vibrating against the refrigerator frame causing a loud vibration. If none of these apply gently press on the side and front panel of the refrigerator to try and locate the source of the vibration as any where metal is vibrating against metal the side and front panel act as a sounding board amplifying the sound. If you cant locate the vibration then you may have a more serious problem and may need to call a technician.

sounds like head pressure problem it is most likely clogged on condenser try washing out really good then try again

The fan could have an obstuction. I have heard of tech sheets getting into the fan and causing a vibration and vibrating sound.

It is the color wheel. Impossible to do this yourself.

We have a double ge wall oven. The vent fans had become really loud. I checked the price for new fans...$275 each! Plus service of $200. If your oven is not too old, go to GE service purchase a 1 year service contract for $93.00. Wait one one month till it takes effect. Call them and request service and the entire replacement is free.

Have someone check the run capacitor of this unit. If the run capacitor is bad over shorted it can cause the unit to run and short cycle on a current overdraw. This makes for an electrical imbalance in the compressor motor. Next step is the compressor is faulty.

Glad that you were able to find the problem.
