I need to replace my the capacitor on my 1.5HP pool pump. Do you carry the capacitor I need?

Please note that capacitors store an electric charge and should be handled with the utmost caution and care. We do not encourage handling a capacitor without any type of safety measures in place and highly recommend contacting a professional service company for repair/replacement. For those that feel comfortable changing the capacitor here's >How to replace a pool pump capacitor. In order to match up the capacitor you will need more specifications on the capacitor. You will need to match the voltage, the MFD, whether or not the capacitor is a >run or >start type and the actual dimensions of the capacitor body.

This capacitor meets all my specs except the size as near as I can tell. Mine is 2.875 long with a 1.875 diameter. Can you tell me the dimensions and if they do not match maybe another model #?
Thank you

Hi Mike, Your current capictor should have a MFD rating and a VAC rating on it, can you please email us those specifications as this will help us select the proper replacement capictor for you, thanks!

In response to the posted question and answer below- my MFD rating is 35 and the VAC is 370 - the only thing in question is the size. Mine is 2.875" long and 1.875" in diameter.

Hi Michael, I double checked the dimensions on this capicitor and it is 2" Wide x 4-5/16" Long. Since the MFD and VAC ratings are the same this would work for your application, the only question would be if it could fit inside your motor end cap.

Hi I have a A.O. Smith corp. 3/4 hp sta-rite pool motor, Motor Mod k48k2p101, SER 7F84 with a bad run capacitor, will this fit?? My capacitor has no numbers or MFD rating on it painted gray primer. Will this one fit and if not what is the proper MFD rating for. Thank you

Is the 3"x3"x2" dimensions only for the body of the capacitor, or does it include the envelope of the connection tabs as well?
I need a 35-370 for a Hayward Northstar motor, but there is basically no space for anything even slightly larger.

Hi Wally, The warehouse confirmed the capacitor is 3" x 2" without contacts.

the capacator in my hayward is a 35mr 370 but it is only 3" in length. The 4 " will not fit in thespace in the motor. Will a 30 mf work and not burn out the 2hp motor?

Hi John, The 30MFD capacitor will not work, it has to be 35MFD or higher.

Can motor SP1620-7-Z-1-MNSC which requires a 55 UF capacitor can it run on one that is 35UF
Reply
Hi, The SP1620-7-Z-1-MNSC motor does show that it can use a 35 MFD 370V Run Capacitor based on the info we have from the manufacturer. In some cases, a higher capacitor can be used.

I am looking for replacement capacitors for 35UF+-5%, 370VAC, 60/50HZ and 30UF+-6%, 370VAC, 50/60HZ. WOULD YOU PLEASE TELL ME THE PART NUMBERS, WHICH WILL REPLACE THESE CAPACITORS? They are for pool pumps. thank you for your help.

Just received my replacement run capacitor...Which terminal connects to the red or black wire from the pump?......I notice that there is a blue dot below one of the capacitors terminals......

Here's a link from our 'How To Guides' on how to replace a capacitor. This does a good of explaining what needs to be done.

I have a 2 HP AO Smith (Whispeflo) motor and the capacitor just went out. It is a 35MFD 370 VAC capacitor. I have temporarily placed a 50MFD one in my pump motor so it will run for filtration and cleaning of my pool. Is that ok?
Also you sell several different capacitors. Can I buy the 40 or 45 MFD capacitor and not damage motor and get better life/performance from motor or should I stick with the 35MFD ?
Reply
Hi, Steve. It's okay to use a larger sized capacitor like the 50 MFD and it will not harm the motor. We do have a wide range of different size capacitor available. You'll be fine using the 50 MFD capacitor or if you want to put your mind at ease you can purchase the 35 MFD 370 VAC Capacitor.

Hello, I have a Hayward Northstar 2HP pump, model number SP1615-Z-1-MNSC, manufactured around 2004. I need a new capacitor but am unable to read all of the information on the label. The info I am able to read is as follows:
x5UF +/-5% 370VAC/B 60,xxhZ (x's represent unreadable numbers)
25P356H37N30N4X 17586335
The capacitor is 3" tall and 2" wide. Can you tell which replacement capacitor I would need?
Thank you,
Ray

Hi, Ray. This 35 MFD 370 VAC Run Capacitor is the correct replacement for the SP1615-Z-1-MNSC motor.

I have an old tub with a Flowmaster-AquaFlo pump motor that has a run capacitor. The capacitor has no label and I am unable to read the pump motor model # because it is faded. The service to the hot tub is 220vac. I am trying to determine the run capacitor I need.

Without a specific motor model, part or catalog number, or a capacitor part number we would not be able to cross reference for you. If you cannot locate any of that then you can send in images of the capacitor stating all specs and dimensions of it through our support request page or you may need to take it to a local motor shop.

I have a ao smith SP-1620-Z1-BE 2HP, i can not read any info on the run cap. I need to replace the cap

You will require the 5270-05 Run Capacitor for your SP-1620-Z1-BE motor.

I need a run capacitor for A O Smith / Century pump motor sq1202
What run capacitor do I need?
Reply
Hi, Bobby. The replacement run capacitor for the SQ1202 motor is 628318-308 which is the 35 MFD 370 Volt Run Capacitor, but you can use this 35 MFD 370 Volt Run Capacitor - 628318-309 also.

I am trouble-shooting a 1999 Sundance 850 Spa system. One of the motors just hums when asked to run. It turns freely by hand. I pulled the capacitor from the external hump on the motor and it seems to test bad on my multimeter.
2 Questions, please:
1) Is this a run or a start capacitor or both?
2) It is marked as a Magnetek 9845. 35uf 370 VAC 60hz 035864. Other numbers on it are 005-1479-RMF SU 60P68-2445 60P61-10 SA S1000AFC 175863-35. What capacitor do you have for replacement?

I have a Waterway pump, m/n PF-20-1N22M, the capacitor is a C107558550061, 35uF, 370 VAC, is this the right capacitor? Mine is 2 7/8" tall (excluding terminals) & 1 15/16" diameter.

Hi Tom, this is the correct capacitor for your motor model SP1615-Z-1-BNSC.

I have an A.O. Smith 3/4 HP Pool pump 220/115 that is sometimes humming when I turn it on. I believe it may be the run capacitor? The run capacitor is a CSC Eccol ii 30 uF 370 vac.B 50/60 Hz. Can you direct me to the correct replacement capacitor?

Hi Randy, could you send us a few photos of the motor label? To supply photos simply click the reply link below and upload your photos. Once we get those photos we can make the proper recommendation.

Hayward Northstar SP4000 or Hayward Northstar SP4000x
I know specs are correct, size - not sure, but pretty close. Mine seems to be 2" in diameter and almost 3" height.
I see the length of yours is smaller, which I guess is OK (housing is slightly longer), but the diameter worries me since it'll be loose in the housing (like a cradle around it). I'd prefer to have exact fit but if not, what can I use to secure it in place considering it gets very hot?
Thanks
Hi We do show that this capacitor has been used on the Hayward Northstar Pumps and would be the correct capacitor for you.

I've been going through capacitors too often in my opinion. The pump is approximately 2.5 yrs old. I have been through 4 capacitors to date. Can you recommend one that may have more longevity? I have attached photos of the motor and existing functioning capacitor.
Hi Rich, there are a few different possibilities for this. Your motor may have had the incorrect capacitor installed from the beginning (I do not have a cross-reference, so I cannot confirm what the correct one is) so you may be replacing it with the incorrect one. If the motor runs lightly-loaded, also known as hot, it can cause high capacitor voltage, ultimately leading to failure. Light-loading or running hot can occur due to restrictions, such as a dirty filter or an air leak. Since you are having this problem repeatedly, it’s probably not the capacitor. The windings may be going bad in the motor, for whatever reason, or the bearings are going bad and it’s running hot. If this is the cause of your capacitor failures, then it is best to replace the whole motor. Our article on Why is my pool pump motor capacitor failing? explains it better.

I have a run capacitor CDE 628318-309, what would be the correct replacement? 35uf +/-6% 370VAC 50/60hz SFS37S35H288B

Hi Barb, this RUN CAPACITOR, 35 MFD (RD-35-370) will be a perfect replacement.

Hi, there --
What would be the correct replacement capacitor for the one I have, that I think has failed?
Many thanks!
The U.S. Seal Run Capacitor, 35 MFD - RD-35-370 will replace that one perfectly. If you have a multimeter, here is how to check your pool pump capacitor and here is a guide on how to replace it safely.
