Start capacitors
Start capacitors above 20 microfarads (µF) are always non-polarized Aluminum Electrolyic Capacitors with non solid electrolyte and therefore they are only applicable for the short motor starting time.
Start capacitors briefly increase motor starting torque and allow a motor to be cycled on and off rapidly Start capacitors have ratings above 70 microfarads (µF), with four major voltage classifications: 125 V, 165V, 250 V, and 330 V. A start capacitor stays in the circuit long enough to rapidly bring the motor to 3/4 of full speed and is then taken out of the circuit, such as by a
centrifugal switch
that releases at that speed. The motor after that runs more efficiently with a run capacitor.
Examples of motor capacitors are: a 35 µF/mfd, at 370 V, run capacitor, or an 88–108 µF/mfd at 250 V start capacitor.
Failure modes
A faulty run capacitor often becomes swollen, with the sides or ends bowed or bulged out further than usual: it can be clear to see that the capacitor has failed because it is swollen or even blown apart with capacitor oil leaking. Some capacitors are built with a "Pressure Sensitive Interrupter" design that causes them to fail before internal pressures can cause serious injury. One design causes the top of the capacitor to expand and break internal wiring.
"Weak Capacitor" - Over many years of use the capacity of the capacitor (measured in microfarads) reduces. As a result the motor may fail to start or run at full power.
