How do you know if a capacitor is damaged?
Use the multimeter and read the voltage on the capacitor leads. The voltage should read near 9 volts. The voltage will discharge rapidly to 0V because the capacitor is discharging through the multimeter. If the capacitor will not retain that voltage, it is defective and should be replaced.
Can I bypass a capacitor?
Start by defining placement. A bypass capacitor should be located as close as possible to the power-supply pin of each chip (Fig. 1). Any extra distance translates into additional series inductance, which lowers the self-resonant frequency (useful bandwidth) of the bypass capacitor.
Why do AC capacitors fail?
Reasons for AC Capacitor Problems Physical damage to the capacitor, such as from debris hitting the unit. Improper voltage or current traveling through the capacitor. Overheating of the unit. Age related wear and tear.

Can a capacitor get weak?
Power surges can cause a capacitor to fail, too. Those weaker surges can be caused by fluctuations in the electrical grid. It can effect even something as simple as large appliances in your home turning on and off.
How do I test a capacitor?
Connect the leads of the capacitor to the multimeter probes and observe the readings on the multimeter. For a good capacitor, the resistance will be low in the beginning and will gradually increase. If the resistance is low at all times, the capacitor is a Shorted Capacitor and we have to replace it.
What happens if a capacitor fails?
A run capacitor is an energy-saving device that is in the motor circuit at all times. If a run capacitor fails, the motor can display a variety of problems including not starting, overheating, and vibrating. A bad run capacitor deprives the motor of the full voltage it needs to operate correctly.

Do old AC capacitors have bad capacitors?
Older air conditioners are more likely to have bad capacitors than newer ACs. The old AC capacitor does not work correctly, so it can also be a symptom of a bad capacitor
Step 1: Tools Needed
Checking the capacitor just requires your eyeballs but replacing them requires a few tools: - Screwdriver, hex wrench, or whatever's needed to open the case - Soldering iron - Replacement capacitors (you will find the values for this in the following steps) Also optional but helpful is soldering wick, which is available for fairly cheap at Radio Shack. In this example I'm repairing a digital TV converter box that will power on, but does not activate from standby..
Step 2: Open the Case
Most important: power off and unplug your unit! Using your screwdriver or other tools, open up the electronics case so that you have easy access to the circuit board.
Step 3: What a Blown Capacitor Looks Like
A busted capacitor can be obviously broken (leaking brownish fluid, corroded, or with the leads severed), but sometimes it's subtle. The top of a blown capacitor will be slightly bent outwards in a convex shape, rather than flat or slightly indented inwards like a working capacitor.
Step 4: Remove the Old Capacitor
Make a note of the polarity of the old capacitor, and mark the exact values you'll need for the replacement: capacitance and voltage/temperature ratings (these may be written on the part itself, or you can look up the part number). Press the tip of a heated soldering iron directly onto the solder joint on the back of the circuit board that is holding the old capacitor down.
Step 5: Insert the New Capacitor
Trim the leads of the new capacitor so that they are both even, and will sit at about the same height as the old capacitor. Position the new capacitor leads at the holes where the old capacitor was, with the correct polarity. Just like before, press the tip of the soldering iron directly onto the joint in the back of the circuit board.
Step 6: Working Now!
Replace the circuit board in its case and test the power and output. The electronics should work now!

What happens if a capacitor isn't powered up?
If the capacitor isn’t powered up for an extended period, the oxide will degrade beyond the point of self-repair. The manufacturer forms the oxide layer by careful application of a forming voltage into the freshly-made capacitor. This not only creates the dielectric layer but also sets the expected current direction.
What is the insulator between the dielectric and the capacitor?
The other plate is conductive fluid. The insulator between (the dielectric) is a very thin layer of oxide that forms on the spiral. Over time, the oxide degrades, but this degradation repairs itself when using the capacitor.
