I have a Waterway Campion 56 Frame pump with a Century Centurion part # 7-177216-24 1.5 HP motor that has the humming then click off actions. Which capacitor does this pump take?

A  Answered on 4/20/2022 by InyoPools Product Specialist Rich N.

Hi John, your motor takes this RUN CAPACITOR, 30 MFD (5VR0303) (2444).  View our guide on How To Replace a Pool Pump Capacitor for tips on how to safely replace it.

Hi there, I have AO Smith Motor 7-187694 -01, it is a 2.5HP water pump. Speed one does not engage and it hums, however, speed 2 engages every time with no issues. I can get speed 1 to work if the shaft is already turning. What capacitor would I need in this case? I only see one on the motor which is 628318-307. Please advise!
 Reply

A  Answered on 11/18/2021 by InyoPools Product Specialist Joe S.

Hello Luke, that is a sign of a bad start capacitor that needs to be replaced. You will need to order START CAPACITOR, 189-227 MFD (PTMJ189).

I have a A O Smith 1 1/2 HP pump that hums when the pump is turned on> I think it's the capacitor. How do I find out if it's bad and what is the correct capacitor for a ST1152 model?
 Reply

A  Answered on 10/11/2021 by InyoPools Product Specialist Rich N.

Hi Tim, as you know, a failed capacitor will prevent the motor from turning over. Another cause of humming could be a seized motor shaft. If you can spin the motor shaft manually, the capacitor is likely the cause of the humming. If the shaft does not spin manually, the bearings or complete motor should be replaced.  Your motor has this start capacitor, 124-149 MFD as well as this run capacitor, 25MFD 370V.  This video on What’s the Difference Between a Start and Run Capacitor? helps explain it a bit and this article on How to Test a Pool Pump Capacitor will help you test them, but I would bet your start capacitor is the culprit.

I have a centurion 7-164304-24. It's making noise (loud hum) and the motor case is hot to the touch. I dont think its cavitataing, but it had been sucking air for a few days. Any ideas?

 Reply

A  Answered on 4/24/2020 by InyoPools Product Specialist Patrick P.

Hi Jeffrey, These are all classic signs that your motor needs to be replaced. The correct replacement motor the motor included in your photo is this B129 1.5 HP Motor. You will also need a Hayward Super Pump Seal Kit when you replace your motor. We put together this Video on How to Replace a Pool Pump Motor which you may find helpful when you tackle this project.

Hi, Janette. Based on the current info we have, the AO Smith USN1252 motor (part # 7-193689-03) motor, uses the Rune Capacitor 35 MFD, 370 VAC - 628318-309

?     Asked on 7/4/2019by Alan T Vose

Will this part # 628318-307, fit my motor, #628318-308, and is there any difference between a run capacitor and a start capacitor?
 Reply

A  Answered on 7/11/2019 by InyoPools Product Specialist Matt S.

The capacitor you need is that 628318-308 number you provided, and it is the 30 MFD (5VR0303). Yes there is the difference between the two capacitors, hence the different ratings and names.

Thank you for all the great advice! A pool company wants to charge me for a new motor, but it sounds like it's just the capacitor. What is the correct capacitor for an AO Smith SQ1072 Motor Model #C48K2PA105C4? Thank you.
 Reply

A  Answered on 6/3/2019 by InyoPools Product Specialist Lennox H.

Hi, Doug. The SQ1072 motor uses the BC161 - Start Capacitor.

Hi, I have the following motor: https://imgur.com/KPs3Ux3 Can you confirm this is the correct capacitor for it? the model # matches, but the capacitor in the photo appears shorter than the one in my motor. Also, the pump runs fine at high speed, but hums and doesn't run at low speed, could that be the other capacitor? or this one?
 Reply

A  Answered on 10/10/2019 by Industry Professional

If you have another capacitor it is the start capacitor & probably will be the one that is faulty. It does sound like the issue. We are not able to determine the correct one based on model info as the mfg will use different ones on the same model. We I.D. them based on the MFD or UF rating on the capacitor.

Unfortunately, we do not have the listing for the capacitor that belongs to this motor. You may contact Regal Beloit, the manufacturer of both Century and A.O. Smith motors, with the serial number, so they may cross-reference the capacitor part number needed. Their phone number is 1.800.537.4856. You may also find the links provided below, helpful in attempting to identify the capacitor based on the information on the capacitor label. http://www.inyopools.com/pump_motor_parts.aspx?Keywords=CAPACITORS , How To Select the Right Capacitor For Your Pool Pump Motor , How To Replace a Pool Pump Capacitor

is there any way to test a capacitor as good or bad
 Reply

A  Answered on 10/19/2016 by InyoPools Product Specialist Stacey M.

Hello, To test the capacitor with a multimeter, set the meter to read in the high ohms range, somewhere above 10k and 1m ohms. 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. There is also a testing video.

What is Service Factor?
 Reply

A  Answered on 1/11/2012 by InyoPools Product Specialist Patrick P.

Service Factor(SF) is a multiplier that when multiplied by the horsepower of the motor indicates the total permissible horsepower loading that may be carried when the motor is operating at rated voltage and frequency. The most important thing to remember when replacing a motor is that the replacement motor's horsepower times its service factor must be equal to or greater than the original motor's horsepower times its service factor. The Service Factor rating can be found on the motor label. See Step 4 of our How to Read a Pool Motor Label guide.
