The start capacitor (161-193 uF, 125V) failed (black goo everywhere, motor would hum but not turnover) and I replaced it and then it failed again (brown goo everywhere) after about 1 week of use. Try taking the motor into a pool store to see if they can test it for you. One model of compressor motor start capacitor. 3. we have a single phase submersible motor, rated 5hp at 230v, and operates on capacitor start controller. A residential pool pump uses a standard electric motor, which is usually between 1/2 hp up to and including 3 hp. ” Attie says: May 31, 2019 at 11:34 PM Hi, I have a question. Also, look at our guide on "How To Use a Multimeter to Test a Pool Pump Motor - Winding Resistance" to check out the motor windings. 1. Uncategorized pool pump motor keeps blowing capacitor. The higher the capacitance of the capacitor the more energy it can store. In searching for a solution I have found this: replaced capacitor and switch plate assbly. Right away it's obvious that this amount of power has the potential to generate a lot of heat. The replacement capacitor is not a motor starting type capacitor of the proper voltage rating. Replaced with same and blew immediately. Reply Pool Pumps Service Sharper Image Pools Tampa Bay. After 3yrs no problems , one of the capacitors blew, motor would not start. Pump is recently new as is control switch/head bleed valve. Pool pumps are supposed to be completely airtight: this is what keeps them primed and sucking water properly. Posted on November 30, 2020 by November 30, 2020 by Here is a guide on "How To Replace AO Smith Motor Parts - Overview" that shows you what electrical parts may be involved. A motor starting capacitor is a non-polarized electrolytic capacitor that is rated for motor starting duty. 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. had motor serviced at electric motor shop. A bad motor capacitor may cause starting problems or could shut off the motor while running. I had a capacitor go bad on that pump before, with a bad capacitor the motor would hum until the motor thermal overload switch opened but it never took-out the breaker. A damaged or burnt out capacitor may hold only a fraction of the energy needed for the motor if its capacitance is low. i replaced the burnt capacitor with same microfarad rating, and it blew up again, replaced it with a higher reting microfarad capacitor, still the same thing happened. I recently had a similar problem with a 7 year old Pentair 1 HP single speed pump drawing excessive current and tripping the supply breaker. I have an Optiflo Pentair 1.5 hp above ground pump and want to switch over to a sand filter. I have a 28 ft round semi in-ground pool. 99. Motor capacitors store electrical energy for the motor to use. When the motor is close to running speed, the Start capaciotor is switched out of the winding circuits. CAPACITOR TYPES - A pool pump can have two types of capacitors: a Start capacitor and A Run Capacitor. To understand why, you first need to understand how an electric motor works along with some basic electrical theory. problem is the capacitor keeps blowing up. I have a Welch Vacuum Pump which contains an Emerson 8917A motor (0.5 HP, single phase, 120V, 4.6 amps). From electrical theory we know that 1 hp is equal to 746 watts of power. 7 thoughts on “ PSC Ep. 86: Why is my pool pump motor capacitor failing? Pool pumps may have two capacitors, one in the back (the start capacitor) and one on top (the run capacitor). The start controller or centrifugal switch is defective and not disconnecting the capacitor when the motor comes up to speed. 2.
