Generally a 0.01~0.1uF capacitor is wired across brushed DC motors to reduce radio frequency EMI caused by arcing between the brushes and commutator. Sometimes two capacitors are wired in series, with the center connection going to the case to ''ground'' it at RF frequencies. For best effect the capacitor(s) should be placed on or inside the motor.
You can almost always replace a capacitor with one of a higher voltage. This is the limiting factor of a capacitor due to dielectric breakdown voltages that the manufacturer chose. Varying capacitance gets a little trickier. If the property of capacitance is used for power supply filtering, then it is generally fine to increase the value.
The starting capacitor is the largest difference in the various 5-2-1 devices. You don''t want too large of a starting capacitor. You need to use the correct one for your application. FYI: Multiply the load amps by 2,650. Divide this number by the supply voltage. The resulting number is the capacity of the capacitor you need in microfarads (µF).
Beyond single-phase capacitors, some ceiling fan motors also use a second type of capacitor known as a run capacitor. This type of capacitor is used to help the fan motor maintain a constant speed and reduce energy …
The fan side of the replacement capacitor the guy got (dual cap) was 10 mfd instead of 5mfd (original). The fan would turn on and run for a short time (30 minutes as I recall) and then turn off (motor was overheating). After the guy got the correct capacitor (5 mfd) the fan worked normally and he reported that it ran for 2 hours without a problem.
Yes, both can technically run without a capacitor, just not very well. They have almost no torque and overheat very quickly being overloaded. Some compressors will actually …

Pro tip on a fan capacitor: There''s an old trick to determine if your fan motor capacitor is bad. When an AC cycle (AC or heat cycle with a heat pump) begins, use a stick to push a blade of the fan to give it the boost of energy a capacitor normally would. If the fan starts spinning – and keeps spinning – then the capacitor failed to give ...
Fixing A Ceiling Fan Remote Control. Ceiling fans with factory remote controls don''t use traditional capacitors to control fan speed. The remote receiver varies the voltage and current to change the fan motor speed. But ceiling fan remote control units can go bad too. Before you even think about tearing the fan apart to diagnose a problem, replace the batteries …
