A capacitor showing short across with a multimeter is definite gone. Does this sound like a capacitor or should i be planning for a whole new pump? My pump runs for 5-10 seconds and shuts off. . Motor not humming ! Most pool pump motors utilize a start capacitor and/or a run capacitor. I have ~123 volts while it is on and does not drop or spike voltage. What is the difference between the two? The motor is #AE100GLL-Y. It sounds like a bad phase winding. If it’s not the capacitor, it’s likely a bad phase winding and the motor needs to be replaced. My pump started making a loud sound then it just cut off. On 2017-03-20 by (mod) re: capacitor for a 1.5 Hp submersible pump. Other symptoms of a pool motor overheating would be an oversized impeller, bad windings or high voltage. ‘5. checked pump motor shaft spins fine not frozen First…. Most pool motors require extra torque to get the motor up to speed. Once you kick start the pump, it runs til your heat switch kills it. I’ll take a look at the Cap but I believe the motor is 230v. Circuit breakers are good and there is power to motor ! A capacitor showing short across with a multimeter is definite gone. First, remove a cylinder from inside the pool pump’s housing. Often times, if your motor is less than 5-7 years old and it fails, the real problem may be the start capacitor. CAPACITOR: The Capacitor is the battery for your pool motor. It is common for pool motors to run on the hot side. This guide gives you a few other things to check: My Pool Pump Runs On Low Speed But Not On High Speed. Do I have to take this off to get the information that I need to order the correct capacitor to try or is the information that I gave above enough to know which to order? What do you suggest i do? There are a couple reasons why a two-speed pool pump motor would only run on high or low speed. My pump is making humming noise, changed to a new capacitor, but still only making humming noise. If your pool pump is not starting, but instead gives a ‘hum’ or a ‘nnngh!’ type of sound, you may have a capacitor problem. Thx, The run capacitor is the 628318-307 and the start capacitor is PTMJ189. Remove the leads to the pool pump capacitor. A capacitor is about $23.00, the replacement motor is around $300.00. The capacitor in an induction motor is used to shift the starter winding current by 90 degrees so the motor will spin up from a dead stop. Flower Mound Pool Care and Maintenance LLC, Lewsiville - Main Office The picture you posted is the run capacitor. The Start capacitor is switched into the the motor's winding circuits on start up to help the motor turn over and come up to speed. However, the motor will shut itself down if it is running too hot. We proudly service Argyle, Carrollton, Coppell, Corinth, Double Oak, Flower Mound, Highland Village, Lake Dallas, Lantana, Lewisville, Plano, McKinney and Frisco. Manufacturer is Pentair SuperFlo. Is your pool pump motor humming, but not turning on? Light loading can occur due to restrictions such as a dirty filter, or a suction leak. Other times, they will be weakened enough that eventually, they will trip the motor overload. However, there is also another issue that can cause this humming sound—a bad capacitor. A motor’s main purpose is to power the pump’s impeller, which is the device that moves the pool water into and through the pump. Woke up this morning and pool pump was not running. Thanks for your attention. If meter remains at 0, you know that the capacitor is bad. This taxes the capacitor and ages it rather quickly. Amana a/c unit, condenser fan bad, changed out and changed the recommended capacitor for it, however, it went from a 3 port to a 2 port capacitor. 86: Why is my pool pump motor capacitor failing? Other symptoms of a pool motor overheating would be an oversized impeller, bad windings or high voltage. Genteq 97F9606. Taking the time to find the right pump motor will extend the life of your pool pump, saving you time and money. The capacitor is under the bump on top of the motor. It will need to be shorted out by placing an insulated screwdriver across the leads of the capacitor. There is a run capacitor and a start capacitor. Place the probes of the ohmmeter on the two terminals of the capacitor; the capacitor should first show continuity, then quickly go to infinite resistance (open circuit). Will come back on maybe about 3-5 minutes later and repeat the same thing. Hello Rob – It sounds like a bad start capacitor. 2 yellow wires, together on old and a red wire on another port. A defective run capacitor can cause the motor to run at a higher amperage. Does it matter If capacitors are bad if there is no “humming” from motor ?! It will sometimes run at high speed if I flip from low to high while it is already running but then it shuts down a short time later (overheating?). Bad AC Capacitor Symptoms. Do you sell this? This sound indicates that the pool pump capacitor has become dead. Now once you reset it it trips immediate However, most motors automatically shut down if they get too hot. Check the winding resistance and the voltage of the lines feeding the motor. A bad capacitor may lead to the motor running at a higher amperage than it should. CAUTION: Capacitors have … The motor may be dead if you have power properly applied and you hear no noise. The can turn the impeller freely from the back. If you can spin the motor shaft manually, the capacitor is likely the cause of the humming. That is why many well pump users do not realize the need for routine maintenance until when it is too late. If can also alter the AC phase leading to other bad things. My question is this – I didn’t take the capacitor cover off last night because it was almost dark. This sound indicates that the pool pump capacitor has become dead. A pool pump is driven by a motor that starts under power from a capacitor. What’s the part number for the start capacitor for the SF-N1-3/4A (340037) ? A failed capacitor will cause the motor to hum or buzz when the start cycle is activated. What gives? Then I noted that the motor starting capacitor on the 1HP motor was the same as for the problem 2HP pool pump motor.
