How to test capacitor.
If the motor hums strongly but doesn’t start, the motor itself is likely good and raring to go, but the capacitor isn’t providing the necessary power. The capacitor is either dead or dying. 3. The furnace goes off. Sometimes the furnace may go off within seconds of realizing that the blower motor is not operational.
This test will only show if the capacitor is completely dead, or not. It will not determine if the capacitor is in good or poor condition. To determine if a capacitor is functioning at the right value (capacitance), a capacitor tester will be necessary. Of course, this also holds true to determine the value of an unknown capacitor.This test will only show if the capacitor is completely dead, or not. It will not determine if the capacitor is in good or poor condition. To determine if a capacitor is functioning at the right value (capacitance), a capacitor tester will be necessary. Of course, this also holds true to determine the value of an unknown capacitor.By taking the capacitor's resistance, we can determine whether the capacitor is good or bad.

Find out how to measure capacitance, resistance, voltage, and polarity of capacitors. Set the Multimeter knob to Ohm (unit of Resistance) or the Greek letter omega (*), as shown in Figure 1. Connect the Multimeter leads to the capacitor terminals again, ensuring that the red one is on the positive and the black one is on the negative. The first resistance reading that appears on display should be noted. Steps To Test A Capacitor By Measuring The Time Constant. First, confirm that the capacitor is disconnected from the board and is correctly discharged. Connect a known resistor (typically a ten KΩ Resistor) serial with the capacitor. Complete the circuit by connecting an influence supply of known voltage.

It might be nearly instant if it is small enough of a capacitance. Either way it should test as open or way up there shortly. This being said there are two possibilities for that cap. If it is 115V then it is a single phase motor. This means that it is either a capacitor start or a capacitor run motor.
See the attached. Short across the capacitor leads to discharge it completely. When the short is removed, it should take approximately 3 seconds to get within 4/5 of the supply voltage. If it's a lot less than 3 seconds, the cap is open. If it never comes up near the supply voltage, it may have excessive leakage current.How To Check Run Capacitors Under Load. 1.
