What happens when AC capacitor goes bad?

A bad capacitor prevents the exterior unit from properly functioning, which hinders the cooling process as a whole. Second, improper voltage delivery to exterior unit components forces the system to work harder as it attempts to perform its job. Additional components often sustain damage due to a faulty capacitor.

How long do AC capacitors last?

approximately 20 years
Most are designed to last approximately 20 years, but a number of factors can cause them to wear out more quickly. If your air conditioner cycles much more rapidly than average, your capacitor is undersized (as mentioned above) or it’s built from problematic parts, and the estimated life span may be greatly reduced.

What does a capacitor do in an air conditioner?

What does an ac capacitor do? The device’s role is to supply and store electrical energy. When you power your air conditioner, the capacitor produces a high-voltage jolt between 400-600 volts and supplies it to the blower motor, fan motor, and the compressor.

How does a capacitor work on a motor?

Capacitors can be thought of as short-term batteries. They are small and shaped like cylinders, and they store their energy within an electrostatic field. When they are properly attached to motors, they send an electrical signal that starts the motor or a series of jolts to the motor to keep in running.
