5 Signs That Indicate Your AC Fan Motor Is Bad
Check the Capacitor. The start capacitor is a cylindrical component and plays a vital role in starting up your AC. The capacitor supplies the electric charge, which starts the condenser fan motor. Without that boost of power, the fan motor is unable to start. That''s why when the capacitor stops working, so does the air conditioner.

6.1.2: Capacitance and Capacitors
Capacitors are available in a wide range of capacitance values, from just a few picofarads to well in excess of a farad, a range of over 10(^{12}). Unlike resistors, whose physical size relates to their power rating and not their resistance value, the physical size of a capacitor is related to both its capacitance and its voltage rating (a consequence of Equation ref{8.4}. Modest surface ...
What''s a Good GPU Temperature Range?
It''s normal for idle temperatures to be a few degrees above the ambient temperature of the room.

Everything You Need To Know About Fan Capacitor
When you have a capacitor with a capacity significantly more than that required by your electric fan, it may cause the motor to run at a much higher speed than normal, finally overheating and burning. As a result, it is preferable to have it updated in the capacity that your electric fan requires.
electrical
It is exceedingly normal for motor capacitors to require rating considerably above the supply voltage. More basically, the motor label is "manufacturer instructions" and code says you follow those. One possibility with your symptoms would be that the compressor motor is fine, and the outside unit fan motor (which appears to be separate) is not running sometimes, …

Choosing the Right Polymer Capacitor
Solid Tantalum Capacitors were invented in the 1950''s. They used manganese dioxide (MnO 2) as the cathode because of its self-healing properties: it becomes non-conductive at defects in the dielectric and this is one of the reasons these capacitors are reliable. Conductive polymers began to replace MnO 2 in the Mid-1990''s. They are more conductive than MnO 2 …
