SOURCE: outside makes loud noise

I would take a very close look at every solder joint there is between the inside unit and the outside. If you observe oil at any point it indicates a leak at that point. That is an expensive price for what you say was done. Check your invoice for the amount of refrigerant they or he added to the system. Compare it with the amount stated on the outside unit nameplate. Check for frost on the suction (big line) by the outside unit. If there is frost your coil is frozen up. If this is the case turn the fan on and the cooling off. Allow it to run in this manor for about an hour to defrost the A coil. Then return to the cooling mode.

Check for blockage of the air pathway. Check that the fan turns freely, as the bearings or bushings could be shot. The fan blades could also be loose. You might just want to replace the fan, as it is cheaper than replacing bushing/bearings.

SOURCE: air conditioner

If the fan blows cold air the compressor is already on.

SOURCE: Fan motor has loud screech.

Check for oil ports on motor. Usually red or yelloe plug in caps. No more than 20 drops of oil. I usually use sewing machine oil.

SOURCE: central air conditioner doesn't cool

The capacitor is located inside the control panel on the outside unit. It is round or oval and silver in color.It runs the outdoor fan and the compressor both.
The terminals are marked= C, /F or fan/, H or herm. C-F-H.
The microfarad rating is printed on the capacitor. Make a color code wire diagram before removeing wires.
Disconnect power to the unit. Use a insulated screwdriver to short out the terminals on the capacitor before removing it.

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..

Unit lights up and hums but does not blow air


mcdevito75 here, Sounds like the fan motor is haging up or needs to be replaced, try the switch on/off then on/off a few times see if the fan kicks on, if not see your local a/c repair shop, they come to the house.

check capicitor on motor, fan motor bearings may be locking up when they get hot then when cooled the motor comes back on. Then you must replace fan motor.

Loud screeching noise coming from the unit.


A screeching or squealing noise usually comes from the fan motor. There may be an oil port and you can buy a small telescoping oil bottle at a super hardware store or an a/c supply house. Before putting in he oil, remember to TURN OFF THE POWER TO THE UNIT and only use a light squeeze on the bottle - over oiling will cause a mess inside the motor. It may be a sealed motor and no oil ports. In either case, budget for a new motor as if it's to the squealing stage, the bearings are already damaged and it's a just matter of time before before the motor bearings fail. If possible, get oil on the bearings ASAP - and use the proper lightweight oil for made for this application.

Get a screeching sound from unit when heater is on.


Chances are it is the outdoor fan motor. Does it squal when you run the A/C? If not it could be the reversing valve solonoid.

Comp shuts off


Coils could be dirty. Compressor could be getting too hot and cutting off. Will have one fan motor that turns condenser fan and evaporator blower.
