Motor capacitors store electrical energy for the motor to use. There are basically two types of capacitors used on small pool pump motors commonly found on residential in ground pool systems. The buzzing noise will not be accompanied by rotation sounds from the impeller of the pump. ... a day or two of not running will not result in anything bad. 24. The smaller, black capacitors, located in the rear of a motor, are usually labeled with a range of numbers, i.e., 161-193 MFD, while the larger, silver capacitors, typically located on the hump of the motor, on top – are sized by a UF number. When you turn on your pump and the motor produces a humming sound, the motor may be ceased so that it won't turn or you may have a bad capacitor. This taxes the capacitor and ages it rather quickly. Many single-phase compressors require a start capacitor to assist in starting the motor. Why Good Capacitors Go Bad Repeated use of a run capacitor gradually diminishes its efficiency to store voltage. In most cases, when a pump truly "goes bad" it means that there are problems with the electrical motor that powers the whole system. 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. Pool pumps may have two capacitors. Re: Pool Pump Capacitor? Hayward SP2615X20 Super Pump 2 HP Pool Pump. I have a pool pump with a 2HP motor. The Difference Between Start And Run Capacitors Both start and run capacitors are made the same way, but run capacitors are much more heavy-duty than start capacitors since a run capacitor is always used when the motor is running. Another reason for the failures, the capacitor is faulty from the start, either it is from a bad batch or mishandled before it installed. Great. Sounds like your run capacitor is blown. Many pool owners do not notice, or simply ignore, small leaks in the equipment room, so it's on you as the service professional to discover these faults and take immediate action. FREE Shipping on orders over $25 shipped by Amazon. A bad capacitor may lead to the motor running at a higher amperage than it should. 99. Hey all, hoping someone here knows a bit about capacitors. $11.99 $ 11. However, most motors automatically shut down if they get too hot. A capacitor is about $23.00, the replacement motor is around $300.00. I checked the impeller, and it is fine. For example, this one is a start capacitor rated at 124-149 MFD and 125 VAC. Electric motor starting & run capacitor troubleshooting FAQs Questions & Answers about Electric Motor Start-Boost or Run Capacitors Capacitors are electric devices that get an electric motor running at start-up or that help keep a motor running once it has started. Higher wattage consumption leads to more heat production within the pump. So I walked out to my pool today and noticed that there was no water movement and the pump had shut off. After some internet searching I found the two most common causes were a stuck impeller or a bad capacitor. Without a capacitor or if it is bad, the motor will just sit there and hum. Hayward Pool Pump Plumbing Problems Pump is Leaking Water. These are commonly found in air-handling applications, residential garage door openers, and increasingly in water pumps. Quick Navigation. The shaft and impeller spin freely. The higher the amps, the higher the wattage. Get it as soon as Tue, Dec 29. With a bad capacitor the motor will try to start, then be saved (usually) by a thermal overload protector that temporarily cuts off power to the motor. Start capacitors have a limited service life of approximately 5000 starts of the pool pump motor. When it cools, it restores power and the motor tries again to start so you hear intermittent humming. Pool pumps are supposed to be completely airtight: this is what keeps them primed and sucking water properly. The Capacitor Start Pool Motor is one of the most common motors found on in-ground pool pumps. Pump Motor Capacitors. My pool pump was making a humming noise, but was not pumping water. $30.24 $ 30.
