Using a multimeter to check capacitorWhen testing polarized capacitors, be sure to connect the multimeter probes properly (connect the capacitor positive lead to the positive probe, and the negative lead to the negative probe). In most cases, the polarity is marked on the casing. It is also important to desolder the capacitor from the PCB (completely or partially), since …This "leakage current" through the dielectric is us­ually converted to the expression "insulation resistance" by using Ohm's Law. "Insulation Resistance", then, is a measure of the ability of the dielectric to withstand the passage of electrons through itself and should not be con­fused with the inherent "series resistance" of the capacitor.

Since capacitors accumulate electrical charge, they must be discharged before checking. This can be done with a screwdriver – you need to touch the leads with a sting to create a spark. You can then call out the component. You can check the capacitor with a multi-tester or with bulbs and wires.

This test method is not suitable for capacitors with a capacitу of less than 0.25 μF. They are checked with a special device – an LC meter. In the absence of a function for determining capacitance, the capacitor is checked as follows: Charge it from a DC source. The source voltage is about half that of the capacitor.Steps To Test A Capacitor By Measuring The Time Constant.

Make sure the capacitor is fully discharged. Set the meter on the Ohmic range (Set it at least on 1000 Ohm = 1kΩ).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.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.Turn a multimeter to the "Ohm" setting. Touch the multimeter's probes on the capacitor's terminals and watch the meter's reading. The meter should reach infinite, fall back slightly, then reach infinite again. If it does not, then replace the capacitor. Replace the wire connectors after testing the control box's capacitor.One of the simplest ways to test a capacitor on a circuit board is to measure its resistance with a multimeter.
