Turn a multimeter to the 'Ohm' setting. It reveals the components of the circuit as streamlined shapes and also the power and signal links in between the tools. Then I noted that the motor starting capacitor on the 1HP motor was the same as for the problem 2HP pool pump motor. Hvordan du Test Capacitor av en Pool Pump Med et multimeter En pool Pumpen drives av en motor som starter under strøm fra en kondensator. To test the capacitor with a multimeter, set the meter to read in the high ohms range, somewhere above 10k and 1m ohms. So, if your motor fails shortly after this, do not immediately go out and replace the motor without first checking the start capacitor. Use a multimeter to verify that the capacitor is bad. AC motors are fairly basic devices that consist of one or more run windings and one or more start windings. If power was applied and it does not run it could be because of a bad starting capacitor. I swapped the two capacitors. Since capacitors store voltage, the multimeter is also capable of reading volts, so if the multimeter being used has a capacitance meter, the actual capacitance value is given. There are other testing methods other than resistance that can be used. A pool pump capacitor is like a battery to start the pump motor similarly to the battery in your car. CAPACITOR: The Capacitor is the battery for your pool motor. Summende støy vil ikke bli ledsaget av rotasjon lyder fra impelleren i pumpen How to test an electric motor capacitor: this article gives a description of electric motor capacitor test procedures to determine if a capcitor is damaged or working normally & test procedures to measure the capactor's capacitance or microfarads, MFD, or uF to determine if it is working within its rated capacitance range. If your pool pump stops, it might not be the pump motor. It provides the energy needed while starting, to reach 3450 rpm quickly. I hope you find this useful. How to Check 115V or 220V with a Voltage Meter ... What Wire To Use For A 220 Well Pump. Here I am testing a start capacitor and a run capacitor for an electric fractional horsepo ... How To Test A Capacitor For An Electric Motor With A Multimeter. Now its just hums, stops, after a while tries to start again, hums - no starting. Pool pumps may have two capacitors. This video will show how to test and install a new capacito… Locate the capacitor and remove it. This morning when I walked outside I heard a loud hum type noise coming from the pump, then after about 10 seconds (before I could get to the pump area) it shut off. If it does not, then replace the capacitor. It … This guide explains how to use a multimeter to measure the AC voltage to your pool pump motor. I rebolted the motor to the pump housing after carefully coating the pump O-ring with a Pool& Spa Lube. Capacitor also doesnt have a pinout legend that i can see. Touch the meter leads to the corresponding leads on the capacitor, red to positive and black to negative.The meter should start at zero and then moving slowly toward infinity. Using the lowest ohms setting, touch the meter leads to the pool pump capacitor's terminals. If you are installing a new pool pump or you have to troubleshoot a failing pump, you will generally want to measure the motors supply voltage, its running amperage and its line continuity. The problem followed the capacitor to the 1HP motor (it now just hummed). Test the capacitor. Before I get a new pump, I thought I would try replacing the capacitor.
