How To Check A Start Capacitor With A Multimeter

Connect the meter leads to the capacitor terminals.

How to check a start capacitor with a multimeter.

If you suspect the capacitor is dead conducting an ohm meter test is the easiest way to find out. Place the red probe on the positive terminal and the black probe on the negative. Disconnect and discharge the capacitor to check a capacitor with an ohm meter you must do two things. Take your multimeter and set it to capacitance.

To test a capacitor by dmm digital multimeter follow the steps given below. Use your digital multimeter dmm to ensure all power to the circuit is off. Connect the multimeter probes to the terminals of the capacitor. You will be taking a measurement reading of the electrical resistance.

Plug the positive and negative gator probes in your multimeter and check the reading. Hold the probes by their base without touching the metal pins on the end. If the capacitor is used in an ac circuit set the multimeter to measure ac voltage. Most multimeters don t have this function though but you can still test a capacitor using the voltmeter or ohm meter setting.

If is used in a dc circuit set the dmm to measure dc voltage. The reading on your multimeter will tell you if the capacitor is working properlyor needs to be replaced. This one covers testing of the start capacitor. How to test an appliance capacitor with a multimeter to test a capacitor to see if it is working you will first need an ohmmeter multimeter.

In case of a polarized capacitor connect the red probe with the positive terminal of the capacitor generally the longer lead and the black probe to the negative terminal. This video is part of the heating and cooling series of training videos made to accompany my websites. Set the meter on ohm range set it at lease 1000ohm 1k. Once both probes come into contact with the terminals on your capacitor the readout on your multimeter will start to change.

Use your multimeter to confirm the capacitor is fully discharged.
