Feature
What does "161-193 uF" mean?
"161-193 µF" in a motor run capacitor spec means it has a capacitance range of 145 to 175 microfarads (µF), determining its ability to store electrical energy. This range should match the motor's requirements for optimal operation.
Can I replace a Motor Start Capacitor with a Motor Run Capacitor?
Start capacitors give a large capacitance value necessary for a motor to start for a very short period of time (usually seconds long). A start capacitor can never be used as a run capacitor because it cannot handle current continuously.
I've installed the Capacitor, but my machine is still not functioning properly. What's the issue?
There might be several reasons for this such as: Incorrect installation, faulty motor, capacitor compatibility or other electrical issues. If the issue persists, please don't hesitate to reach out. We're here to help.
Can a motor start capacitor rated 110-125 volts be hooked up to a 220 volt line input? Will it just burn out?
No. The voltage rating of a capacitor indicates the maximum voltage that it can handle safely. If you put a 110-120 capacitor where a 220V is required, it may start the motor a couple of times but will fail very soon.
Can I repair the faulty Capacitor?
Capacitors are typically not designed for repair and are considered disposable components. We recommend you to replace by a new one.
