I replaced the capacitor and still humming and won’t fire up. Leaks can also come from loose drain plugs or loose on bolts on the seal plate, connecting the motor to the pump. The overheated, dried, and crystallized electrolyte will also try to force its way out the bottom. Pumps are usually known as centrifugal pumps, which cause pool water to move due to the principle of centrifugal force. A higher rating capacitor delivers a higher start current than the motor windings / brushes may be able to withstand, leading to premature failure of the motor. Hello there, but if I press the button and put it on High speed, it will start… then I can reduce it on slow speed and it works… What’s confusing is that most of the time it will start on slow speed… seem like it will not start everytime and humm… is that a capacitor going bad? If the capacitor is charged, the motor is probably bad. After you release the capacitor’s charge, it’s safe to remove the capacitor from the larger cylinder. Overheating. Taking the time to find the right pump motor will extend the life of your pool pump, saving you time and money. It’s important to avoid removing this cylinder when your pool pump is still getting power though. Swimming pools have many different moving parts, and one of those parts is called a pool pump capacitor. Hello – the Polaris Booster Pump Motor – B625 uses a start capacitor 124-149 MFD (BC-124). The replacement start capacitor for the P6E6D-205L should be part number 5270-11. Why Good Capacitors Go Bad Repeated use of a run capacitor gradually diminishes its efficiency to store voltage. There are a couple reasons why a two-speed pool pump motor would only run on high or low speed. I watched one of your videos about capacitors yesterday which inspired me to think that I might be able to fix it on my own. A picture of the motor label would be most helpful. Many single-phase compressors require a start capacitor to assist in starting the motor. Visually inspect your start capacitor for ... something else is wrong with my well pump motor. The same reason your car needs a battery inside the engine bay to start is the same reason a pool needs a capacitor to start. +6 -6 % That is why many well pump users do not realize the need for routine maintenance until when it is too late. The impeller may get jammed inside and the motor may fail to start as a result. Use a multimeter to verify that the capacitor is bad.

Before testing your capacitor, be sure to short across the terminals with an insulated handle screwdriver. Pool pumps are self-priming, which means when started up, they release all the air from the system, creating a vacuum that starts and maintains a suction. Motor not humming ! More Details. Touch the screwdriver to the ends of the capacitor making sure to touch each prong simultaneously. In most cases, when a pump truly "goes bad" it means that there are problems with the electrical motor that powers the whole system. Not sure how to wire it up. Motor has power but seems to be DEAD ! 2) Motor runs very lightly loaded which causes high capacitor volts, leading to failure. Because of this, pool motors with bad capacitors often overheat. I have a Sta-Rite Dyna-Pro-E Pump (2-Speed) #MPEA6YG-207L that will only run on low speed. You can find the pool pump capacitor underneath a hump on either the top or side of your pool pump.
