To do this check, we connect the ohmmeter''s probes to the capacitor''s terminals. Given that resistance is not polarized, it makes no difference which way up it is. Using an Ohmmeter to Measure Capacitor Resistance. If the resistance across the capacitor is very little, or close to 0, then we know the capacitor is broken.
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 …

AC Fan Not Spinning: 6 Outdoor Condenser Fan Problems (+Fixes)
If the bad capacitor is not the issue causing the AC fan not spinning, here is what you check for next: 2. Broken Fan Motor (Most Expensive Issue That Causes AC Fan From Spinning) If you check the outdoor AC unit and see that the AC fan is not spinning, your only wish should be this: "God, I hope something is not wrong with the fan motor."
Common Generator Parts To Fix "No Or Low Voltage"
To discharge, use a screwdriver with an insulated handle to cross the terminals on the capacitor (this will result in a loud pop and a spark). Once discharged, take a reading from the capacitor. The measured capacitance should be +/-5uf of the specified rating printed on the side of the capacitor. If not, the capacitor should be replaced.
What is a Furnace Capacitor and How to Tell If It''s Bad?
The job of the start capacitor is to store that extra power. When the thermostat and control board sends a request to start the motor turning, the capacitor sends that burst of power to get it spinning. A capacitor is a sealed unit, typically shaped like a small can, and can only be replaced, not repaired. Signs of a Bad Furnace Capacitor

What are the behaviors of capacitors and inductors at time t=0?
For an uncharged capacitor connected to ground the other pin (the side of the switch) is also at ground potential. At the instant you close the switch the current goes to ground, that''s what it sees. And the current is the same as when you would connect to ground without the capacitor: a short-circuit is a short-circuit.
