How To Test An Electric Motor Capacitor

The capacitor stores an electrical charge and is comprised of one or more pairs of conductors separated by an insulator.

How to test an electric motor capacitor.

The higher the capacitance of the capacitor the more energy it can store. Use needle nose pliers with an insulated handle to remove wires. Replace the capacitor if it fails the test again. Use a screwdriver to open your machine and locate the capacitor.

Many household appliances have an electric motor start capacitor and when this wears out the motor doesn t have enough energy to cycle on. Run capacitors maintain a fairly consistent voltage supply and increase the torque of hvac motors at startup. You can check to see whether a capacitor is good or bad using an ohm meter but first you have to remove the capacitor from the circuit and discharge it. A bad motor capacitor may cause starting problems or could shut off the motor while running.

How to test an electric motor capacitor. If you need to run a capacitor test on your system there are several safety measures that should be taken. Motor capacitors store electrical energy for the motor to use. Retest the capacitor with the meter.

Capacitors are metal tubes that store an electric charge usually found near a motor in the appliance. This article series gives electric motor start run capacitor and hard.
