Capacitors typically last 10-15 years. In some cases, a capacitor just reaches the end of its lifespan. But sometimes, the capacitor is just a symptom of a bigger issue. For example, if your blower motor is under strain, it''ll make the capacitor work harder as well. So what happens when a furnace capacitor fails?
8.4: Energy Stored in a Capacitor
As the capacitor is being charged, the charge gradually builds up on its plates, and after some time, it reaches the value Q. To move an infinitesimal charge dq from the negative plate to the positive plate (from a lower to a higher potential), the amount of work dW that must be done on dq is (dW = W, dq = frac{q}{C} dq).

Bad AC Capacitor Symptoms: What Should I Watch For?
A capacitor is a small, cylindrical component that helps to provide a power boost to the motor in your AC unit. The capacitor stores energy and then releases it as needed to help the motor start and run smoothly. If the capacitor goes bad, it can cause the air conditioner to short-circuit or overheat, leading to a breakdown.
AC Capacitor Keeps Blowing: What to Do?
Overheating is another common cause of capacitor failure. Air conditioning systems generate heat while operating, and if the system is unable to dissipate this heat properly, it can lead to elevated temperatures within the …
Motor Capacitor Marking Guide
In plain English, this capacitor can be used at voltages up to 370 Volts Alternating Current. Use of this capacitor at lower voltages than 370 VAC is acceptable (so you can use it on a motor powered at 120 VAC Volts-Alternating Current or at 240 VAC). Duty Frequency Range: 50/60 Hz. The capacitor can be used at a frequency range of 50-60 HZ.
Top Cause of Single-Phase Motor Malfunctions | Fluke
Most problems with single-phase motors involve the centrifugal switch, thermal switch, or capacitor(s). If the problem is in the centrifugal switch, thermal switch, or capacitor, the motor is usually serviced and repaired. However, if the motor is more than 10 years old and less than 1 HP, the motor is usually replaced. If the motor is less than 1/8 HP, it is almost always replaced.

Electrolytic capacitor leakage current – what is it and how to …
Essentially, this wastes energy and makes a capacitor behave… well, less like an ideal capacitor and more like a resistor (especially if the leakage current is relatively high). In such cases, the cap is said to be "leaky" (which, by the way, has nothing to do with a bad capacitor that is physically leaking electrolyte.)
