Hello, I have this exact motor and today it stopped running on low speed. It runs smooth and quiet on high normal flow at jets etc. but won't run when switched to low...any thoughts? Thanks for your help.

Hi Daniel, This typically happens when you run capacitor has failed, you may want to try replacing your run capacitor. This motor requires this 628318-309 Run Capacitor

I have a Star rite pump with the SQ1102 motor that died 48Y flang but I want to up grade to a dual speed for the energy savings will this motor work?

A  Answered on 5/20/2019 by InyoPools Product Specialist Patrick P.

Hi Eric, Yes this would be the proper replacement dual speed motor for your SQ1102. Please note that if you are using a standard yellow dial timer to turn your pump on and off then you will need to add this T106R Dual Speed Pool Pump Timer when upgrading to dual speed. Your current timer would power your pump on and off and the second timer would be programmed to switch between the high and low speeds. When you take into consideration the cost of the timer then you might consider this 1.65 HP Variable Speed Replacement Motor as you don't need to purchase a timer with this motor as it the controls are mounted directly to the motor. We wrote this Article on Is a Dual Speed Pump or Variable Speed Pump Right for me which you might find helpful.

I have a Century SQS1102R 1HP 2speed motor that is cycling from hi to lo and back. Does that mean the hi lo switch is bad and do you have the replacement switch?

A  Answered on 2/4/2019 by InyoPools Product Specialist Lennox H.

Hi. It is possible. In order to confirm, you can remove or uninstall the switch to see if it still behave that way.

Will this pump replace a Jandy RO479307 which is a 1.5 HP two speed motor that attaches to a Jandy PlusHP pump?

Hi, Bob. This motor can be used as a replacement, however, the B2982 (56Y) or the SQS1102R (48Y) motors will be the correct replacement with the matching Total HP.

?     Asked on 4/20/2015 by Lauren

I have a Jandy Plus HP pump with the overheating cheap replacement motor. I want to replace this motor but I don't have the exact model on the pump or the original motor. I was told I have to take the pump apart and find out which impeller is in it. Will there be an obvious part number on the impeller if I do this? The original pump was installed in 2010 and was 1 1/2HP 2-spd. This cheap motor is 1 HP 2-spd and shuts off on high speed and doesn't provide flow for the salt gen on low speed.

A  Answered on 4/20/2015 by InyoPools Product Specialist Patrick P.

Hi Lauren, Yes when you remove the impeller there will be a part # embossed into the plastic of the impeller, once you get the part # then email us and we will let you know which model you have. I think I know the reason why your second motor burned up so quickly. When you went down from 1-1/2 HP to 1 HP if you did not down size your impeller to 1 HP then the 1 HP motor is going to be working too hard as it still has the 1-1/2 HP impeller. Basically the 1 HP motor is trying to do the work of a 1-1/2 HP motor. When you purchase the new motor make sure that the HP rating of the impeller matches that of the motor. We can help you figure this out once you supply the impeller part # information.

I'm trying to replace the motor on my pool pump but all these numbers and abbreviations on the motor label are really confusing me. What do they mean?

A  Answered on 1/19/2012 by InyoPools Product Specialist Patrick P.

Replacing a pool pump motor is not as difficult as it seems. You can try looking here. If you need help figuring out what the information on your label means. If you are still having difficulty figuring it out you can call us at our toll free number or you can send us a photo of your motor label here.

How can I tell whether or not my motor is a dual or single speed?

A  Answered on 1/18/2012 by InyoPools Product Specialist Patrick P.

Most dual speed motors will have a toggle switch that will allow you to adjust the motor speed to either high or low. Another way to tell if your motor is dual speed is by looking at the RPM's on the motor specifications label. If there are two RPM's listed such as: 1725/3450 then motor is dual speed. If there is only one RPM, then motor is single speed.

?     Asked on 1/18/2012 by Guest

Can you direct me to the proper hi low switch for this motor?

A  Answered on 1/18/2012 by InyoPools Product Specialist Patrick P.

Unfortunately the manufacturer does not offer the switch for the 2 speed 220v motors any longer. If you already have a 220 volt timer (on/off) you would need an Intermatic T106R to switch from high to low speed. If you do not have a timer currently you would need the T10604R which is a 220v on/off timer and a high/low timer.

Why should I purchase a Tune Up Kit?

A  Answered on 1/12/2012 by InyoPools Product Specialist Patrick P.

A Tune Up Kit includes all of the essential replacement seals and gaskets for the pump. The seals and gaskets should be replaced when installing a new motor on your pump. New seals will prevent the pump from leaking water or losing the prime. A Tune Up Kit will protect your motor and ensure that the pump is working efficiently.

?     Asked on 1/12/2012 by Guest

Why do I need to purchase a new shaft seal?

A  Answered on 1/12/2012 by InyoPools Product Specialist Patrick P.

We strongly recommend replacing the shaft seal. The purpose of a shaft seal is to prevent water from running down the shaft of the motor and into the motor housing. Water will damage the bearings and cause the motor to fail. A new shaft seal should be installed whenever a motor is replaced. The motor manufacturer can deny the warranty if the motor fails to due to water damage from a faulty shaft seal. To find your shaft seal you will need to visit our Pool Pump Parts Page or the Spa Pump Parts Page and select your make and model.

What is Service Factor?

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.

?     Asked on 5/16/2007 by Guest

Can you replace single speed pump motor with dual speed pump motor?

A  Answered on 5/16/2007 by InyoPools Product Specialist Patrick P.

Yes but you can't go with a higher HP than the single speed motor. For example if you have a 1 HP single speed you cannot go with a 1.5 HP dual speed motor; you would be able to use a 1 HP dual speed motor. Customer would need to purchase a toggle switch or timer to switch from high speed to low speed.
