☑ Testing A Dual Capacitor

For a dual run capacitor select the common and herm for the compressor circuit or in a separate test the common and fan for the fan motor circuit. By taking the capacitors resistance we can determine whether the capacitor is good or bad.

For a standard two terminal run capacitor just touch the probes to the only two terminals that will be present.

Testing a dual capacitor. Hold a screwdriver with an insulated. Disconnect the capacitors power source. Connect the meter leads to the capacitor terminals.

Then connect the multimeter leads to the capacitor terminals. Now take the amp reading you took on the start wire wire from the capacitor. Hvac training dual capacitor checkout ron walker.

A very good test you can do is to check a capacitor with your multimeter set on the ohmmeter setting. Electric tech 353549 views. Next measure voltage across the capacitor.

Note the reading and compare with the following results. How to test a capacitor duration. The capacitor provides a relatively low resistance to this pulse of ac current which is why the meter reading fluctuates before settling to the infinite resistance reading youtube user dgk284.

Sometimes a capacitors top will dome outward like a can of soda that is about to explode. Next read the capacitance value on the outside of the capacitor and set your multimeter to its capacitance setting. To do this test we take the ohmmeter and place the probes across the leads of the capacitor.

When testing a run capacitor many techs pull the leads off and use the capacitance setting on their meter to test the capacitor. Pull the wires terminal connectors off of the capacitors wire terminals. On a system that is not running there isnt anything wrong with this test but when you are constantly checking capacitors as a matter of regular testing and maintenance.

How to use an ohm meter to check capacitors step 1. Here are the steps. Measure the amperage of just the start wire wiring connecting to the start winding.

Unsubscribe from ron walker. Take an avo meter. To test a capacitor using a digital multimeter with a capacitance setting start by disconnecting the capacitor from the circuit its a part of.

Label the wires connecting to the capacitor with masking tape. Divide the total of the start wire amps times 2652. Test a capacitor with an ohmmeter of a multimeter.

Test a capacitor by analog multimeter make sure the suspected capacitor is fully discharged. Select analog meter on ohm always select the higher range of ohms. This test is really just a continuity test.
