When your air conditioner suddenly fails, it can be difficult to know where to start identifying the problem.
If the fan doesn't start even when the AC power is turned on, this could be a clear sign of a failed motor. When an air conditioner runs without a fan circulating the air, it eventually causes the evaporator coil to freeze. Once this happens, your air conditioning unit is at greater risk of damage. Turn off AC power and call an HVAC technician.
Also frustrating is that the fan works fine but the blades spin very slowly. A slow-turning fan produces a weak airflow. If your air conditioner offers a different fan setting, check that it is set to low speed. If this is not the case, it may mean that the motor bearings must be oiled, or the capacitors are faulty.

When the fan runs intermittently, it can be one of two problems. First, the motor can overheat, causing it to lose power. Alternatively, loose, connected, or shorted wires in the motor windings could be the culprit.
Any electrical related issues should only be resolved by professionals. For example, never try a fan motor when you suspect an electrical problem. This can be dangerous and is best left to a trained HVAC technician or electrician.
There is more than one reason for the noise of the air conditioner.
If you hear loud rattling noises, it may be a small problem, such as loose rocks or debris stuck in the condensation unit.
Loose or unbalanced fan blades hitting the sides of the fan housing unit can also rattle.
If you don't see any jams in the condensing unit, and the fan blades turn freely and smoothly, the fan motor may be causing it.
If you hear a humming noise, this is another sign that the motor is reaching its end of life.
