How To Check A Start Capacitor With A Multimeter

Place the red probe on the positive terminal and the black probe on the negative.

How to check a start capacitor with a multimeter. 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. Make sure the capacitor is discharged. If the capacitor is used in an ac circuit set the multimeter to measure ac voltage.

In case of non polarized capacitor connect it either way as they do not have polarity. 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. If your capacitor is in working order the reading should start rising and after it reaches a certain point it should start falling because the capacitor has begun to absorb the energy from the multimeter. This video is part of the heating and cooling series of training videos made to accompany my websites.

Once both probes come into contact with the terminals on your capacitor the readout on your multimeter will start to change. Disconnect and discharge the capacitor to check a capacitor with an ohm meter you must do two things. Most multimeters don t have this function though but you can still test a capacitor using the voltmeter or ohm meter setting. Set the meter on ohm range set it at lease 1000ohm 1k.

You will be taking a measurement reading of the electrical resistance. If is used in a dc circuit set the dmm to measure dc voltage. Connect the meter leads to the capacitor terminals. Take your multimeter and set it to capacitance.

Connect the multimeter probes to the terminals of the capacitor. 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. Use your multimeter to confirm the capacitor is fully discharged.

If you suspect the capacitor is dead conducting an ohm meter test is the easiest way to find out.
