The motor capacitor is too large
Larger capacitors typically have larger voltage ratings and hence cool down faster. It could also be due to age (caps shrink with age) or manufacturing capability. In most circumstances, the physical size of the capacitor is directly proportional to the voltage rating. A motor will not run properly if the capacitor is not of the. No, as long as the capacitance and voltage ratings are the same, the physical size of an electrolytic capacitoris unimportant. A possible exception is if the switching power supply.
