Get PriceOnce you''ve completed these steps, you can confidently move forward with testing your garage door capacitor. There are two ways to test the garage door capacitor: with a digital multimeter or by using an ohmmeter. When testing your capacitor with a digital multimeter, measure both terminals of the unit to ensure they are within …
Get PriceIf you want to test a capacitor, you need to provide a voltage that is lower than the capacitor''s rated voltage for a short period of time. To illustrate, consider providing 9 volts to a 25 volt capacitor and allowing it to charge for a few seconds at this voltage.
Get PriceIf you are using a meter with 10 MΩ input resistance and you are testing a 0.1 μF cap, the time constant is one second. If the capacitor is good the meter should indicate zero after eight seconds. If you are testing an electrolytic capacitor calculate the time constant from 220 kΩ times the capacitance in farads.
